ElasticSearch NotFound after purging a collection Posted: 28 Apr 2016 06:59 AM PDT I have a "live-test" environment for my rails application which lets us test our application with near-real production settings (email are sent for real, etc.) I have added some buttons to this "live-test" website that lets us quickly purge a collection (ie. remove all documents from a MongoDB collection) def purge if Rails.env.production? should_not_happen(severity: :armageddon) else Company.unscoped do Company.all.each(&:destroy) end Utility.seed flashy(:info, 'company XXX restored') redirect_back end end The problem rises with ElasticSearch. The first time this purge method is called, it works fine, I have some error Elasticsearch::Transport::Transport::Errors::NotFound in MyController#purge If I click refresh several times on my browser, after 2-3 times the request is finally accepted, but then I have the same problem again : # 1st time executing purge action : Works # 2nd time : [404] {"found":false,"_index":"professionals-test","_type":"employee","_id":"57221655f5ae457700b464a2","_version":4} # 3rd time : [404] {"found":false,"_index":"professionals-test","_type":"employee","_id":"57221655f5ae457700b464a5","_version":6} # 4th time : [404] {"found":false,"_index":"professionals-test","_type":"employee","_id":"57221655f5ae457700b464a7","_version":4} # 5th Time : Works # 6th refresh : Again errors.... I am using AWS ElasticSearch service with the classic elasticsearch ruby gems.

Rails Active Record - find record where the sum of two columns matches criteria Posted: 28 Apr 2016 06:59 AM PDT I have a Property model that has rooms and suites columns. If I want to find all Properties that have rooms > 5, I can easily write: Property.where("rooms > 5") But I want to write a query that finds any Properties that have +5 rooms and suites, so it can be 6 rooms and 0 suites, 0 rooms and 6 suites, 3 rooms and 3 suites or any combination. What matters is that rooms + suites > 5. How would I write such a query?

Get the number of contributors for a repository Posted: 28 Apr 2016 06:50 AM PDT Im using the octokit gem and am following this tutorial. Im trying to get the number of contributors for each repository? I have something like this: <% @repositories.each do |repo| %> <li> <p><b><%= repo[:name].capitalize %></b>: <i><%= repo[:description].capitalize %></i> <b>[Watchers: <%= repo[:watchers] %>, Forks: <%= repo[:forks]%>, Stargazers: <%= repo[:stargazers_count] %>]</b></p> <p><%= repo[:contributions] %></p> </li> <% end %> This does not seem to work, any idea?

Is there a way to assert_select an XHR JQuery response in a Rails controller test? Posted: 28 Apr 2016 06:45 AM PDT In my controller tests, I have assertions like this assert_select "input#name" This works fine for normal HTML requests but it doesn't work with JQuery. The best I've come up with is assert response.body.match /<input .*id=\\\"name\\\".*\/>/ Is there a better way?

Rails Grape routes Posted: 28 Apr 2016 06:40 AM PDT I know this is a stupid question, but I need to help I have project with API on grape. In my routes.rb i mount API mount API::Root => '/' in api/api.rb module API class Root < Grape::API prefix 'api' default_format :json add_swagger_documentation( hide_documentation_path: true, markdown: GrapeSwagger::Markdown::KramdownAdapter ) mount Home::Users end end end i have rout like this POST /api/users/:id What do I need to make that route was without a prefix 'api' POST /users/:id

Paperclip video attachment error using paperclip-av-transcoder Posted: 28 Apr 2016 06:30 AM PDT I am making a Ruby on Rails application and am trying to allow video files to be uploaded through the application. I'm using the paperclip gem to handle the attachment of files, paperclip-av-transcoder gem (as suggested) to handle the transcoding. I also have the aws-sdk gem installed, but that's irrelevant at the moment because I can't even get the uploading to work on my local system. I've followed all the instructions to prepare the application to handle video uploading: I've installed necessary gems, created the actual paperclip for the Video model (I named the paperclip "film"), ran the migration, and added the association to my Video model itself. I also whitelisted the :film attribute in my video controller parameters, and I have the correct field for :film in my new video form. When I run my local server I go to my videos#new page and fill out the form, attach the file for :film, and submit the form. It takes about 10 seconds until it loads the following error: Av::UnableToDetect in VideosController#create Unable to detect any supported library Extracted source (around line #10): @video = Video.new(video_params) I have no idea what's going on here. When I look at other people who have had the exact same error message "Unable to detect any supported library", they always simply forgot to run the paperclip migration or something like that. I've followed all of those necessary steps. Here is my :film related code in my Video.rb model has_attached_file :film, styles: { :medium => { :geometry => "640x480", :format => 'mp4' }, :thumb => { :geometry => "160x120", :format => 'jpeg', :time => 10} }, :processors => [:transcoder] validates_attachment_content_type :film, content_type: /\Avideo\/.*\Z/ and here's my strong parameters in my videos_controller def video_params params.require(:video).permit(:title, :description, :film, :preview_image, award_attributes: [:id, :title, :body, :award_image]) end And here is the database schema relevant to my video model. Preview image is a separate paperclip (its an image), which I've had for a few weeks and it works completely fine. create_table "videos", force: :cascade do |t| t.string "title" t.string "description" t.datetime "created_at", null: false t.datetime "updated_at", null: false t.string "preview_image_file_name" t.string "preview_image_content_type" t.integer "preview_image_file_size" t.datetime "preview_image_updated_at" t.string "film_file_name" t.string "film_content_type" t.integer "film_file_size" t.datetime "film_updated_at" end I also have a feeling it may have something to do with my gems, here's my gemfile: gem 'paperclip', :git=> 'https://github.com/thoughtbot/paperclip', :ref => '523bd46c768226893f23889079a7aa9c73b57d68' gem 'aws-sdk' gem 'paperclip-av-transcoder' I've already tried it with just the plain 'paperclip' gem, with no reference to git. It still doesn't work Thanks in advance for any help you all can give me!

Rails 4 scope has_many Posted: 28 Apr 2016 06:49 AM PDT I have two models class Portfolio < ActiveRecord::Base has_many :project_types, dependent: :destroy end class ProjectType < ActiveRecord::Base belongs_to :portfolio end ProjectType model has field ptype. It can be 'web' or 'mobile', etc. How can I get all 'web' or 'mobile' portfolios using scopes?

Rake extensions in non-development environment Posted: 28 Apr 2016 06:24 AM PDT I use Ruby 2.2.0, Rails 4.2.6 and method String#pathmap. In 1.9.3 it was a String public instance method, but since 2.0.0 it moved into rake/ext/string.rb extention. Problem is that I can use this method in rails console and when i start my localhost all works fine, but it gives me exception in production environment. I restarted Spring, no success. I know how to solve this problem, my question is why it works in one environment and does not work in other?

Restrict editing a resource based resource attribute Posted: 28 Apr 2016 06:55 AM PDT The logic of the application that I currently work on demands a Payment mustn't be editable if its status is open. I see two ways of implementing this: 1 A routing constraint like: constraint: lambda { |req| Payment.find(req.id).status != 'open' } 2 A simple condition in PaymentsController#edit: if @payment.status == 'open' redirect_to payments_path end What option should I go for? Which is more suitable and clean, Rails-ish? Is there any other option? If I go with the first option and have a resources :payments, how can I add the constraint only for the edit route?

rails api dock syntax Posted: 28 Apr 2016 06:06 AM PDT ROR Api Dock always starts with a syntax of the method. My example will be link_to: link_to(name = nil, options = nil, html_options = nil, &block) public My question is on the "name=nil" or "something = nil" which i see on most every command. A second example: url_for(options = nil) Can someone explain what is the point of this or what it is trying to say..does it mean that the option is optional? Why is it important..

net-ldap credentials error due to simple vs generic method. Posted: 28 Apr 2016 06:05 AM PDT I am trying to use net-ldap to query our ldap server. I can authenticate through adauth so the ldap server is responding. I switched from activeldap to net-ldap because I couldn't get a query working with activeldap. I could not get a connection for querying with net-ldap either. I finally traced it to my ldap server apparently wanting a method of 'generic'. However, when I change the settings for net-ldap from simple to generic, I get an error. I used the ldp.exe tool from microsoft to test my ldap connections separately from the rails app. I have the following gems installed. gem 'adauth' # for active directory/rails integration gem 'activeldap' # required with adauth to provide the active directory connection gem 'net-ldap' The index method in my observations controller has the following (Some info is xxx'd out) require 'rubygems' require 'net/ldap' ldap = Net::LDAP.new :host => '10.0.0.22', :port => 389, :base => "dc=xxxxx,dc=com", :auth => { :method => :simple, :username => 'xxxxxx', :bind_dn => "uid=xxxxx,ou='xxxxx',dc=xxxx,dc=com", :password => 'xxxxx' } filter = Net::LDAP::Filter.eq( "cn", "George*" ) treebase = "dc=xxxxx,dc=com" ldap.search( :base => treebase, :filter => filter ) do |entry| puts "DN: #{entry.dn}" entry.each do |attribute, values| puts " #{attribute}:" values.each do |value| puts " --->#{value}" end end end p ldap.get_operation_result when I go to the index, I have ldap.get_operation_result displayed which shows <OpenStruct extended_response=nil, code=49, error_message="80090308: LdapErr: DSID-0C0903A9, comment: AcceptSecurityContext error, data 52e, v1db1\u0000", matched_dn="", message="Invalid Credentials"> 52e says that the password is bad.

'gem install ffi' failed on Mac OS X Yosemite 10.10.5 Posted: 28 Apr 2016 05:39 AM PDT I'm trying to set up a RoR environment under RVM on Mac OS X Yosemite 10.10.5 on my macbook pro.

Patching complete todos in Ruby on Rails 4 Posted: 28 Apr 2016 06:17 AM PDT I'm trying to add the ability to complete a todo item by patching in :complete method.

Money-rails gem - how to overide default currency and show decimal points Posted: 28 Apr 2016 05:48 AM PDT I'm using the rails-money gem for the first time for an events app I'm building. I have an events model which has a 'price' column with type integer. I want the user to be able to type in whatever variation they want (within reason) for the cost of an event - e.g £15.99, 15.99 etc but the show output needs to look tidy and appropriate (£15.99). At the moment my input field allows me to put a decimal point on the form but it doesn't recognise this on the show page (£15.99 just shows as 15). Also, I have a currency select field with the 3 main currencies as choices £/€/$ but whatever choice I make on the show page it comes out as $ so as with the above example £15.99 shows as $15. How do I fix this? This is the code I have at the moment - Event.rb class Event < ActiveRecord::Base belongs_to :category belongs_to :user has_many :bookings has_attached_file :image, styles: { medium: "300x300>" } validates_attachment_content_type :image, :content_type => /\Aimage\/.*\Z/ monetize :price, with_model_currency: :currency end money.rb # encoding : utf-8 MoneyRails.configure do |config| # To set the default currency # #config.default_currency = :gbp # Set default bank object # # Example: # config.default_bank = EuCentralBank.new # Add exchange rates to current money bank object. # (The conversion rate refers to one direction only) # # Example: # config.add_rate "USD", "CAD", 1.24515 # config.add_rate "CAD", "USD", 0.803115 # To handle the inclusion of validations for monetized fields # The default value is true # # config.include_validations = true # Default ActiveRecord migration configuration values for columns: # # config.amount_column = { prefix: '', # column name prefix # postfix: '_cents', # column name postfix # column_name: nil, # full column name (overrides prefix, postfix and accessor name) # type: :integer, # column type # present: true, # column will be created # null: false, # other options will be treated as column options # default: 0 # } # #config.currency_column = { prefix: '', # postfix: '_currency', # column_name: nil, # type: :string, # present: true, # null: false, # default: 'GBP' # } # Register a custom currency # # Example: # config.register_currency = { # :priority => 1, # :iso_code => "EU4", # :name => "Euro with subunit of 4 digits", # :symbol => "€", # :symbol_first => true, # :subunit => "Subcent", # :subunit_to_unit => 10000, # :thousands_separator => ".", # :decimal_mark => "," # } config.register_currency = { "priority": 1, "iso_code": "GBP", "name": "British Pound", "symbol": "£", "alternate_symbols": [], "subunit": "Penny", "subunit_to_unit": 100, "symbol_first": true, "html_entity": "&#x00A3;", "decimal_mark": ".", "thousands_separator": ",", "iso_numeric": "826", "smallest_denomination": 1 } config.register_currency = { "priority": 2, "iso_code": "USD", "name": "United States Dollar", "symbol": "$", "alternate_symbols": ["US$"], "subunit": "Cent", "subunit_to_unit": 100, "symbol_first": true, "html_entity": "$", "decimal_mark": ".", "thousands_separator": ",", "iso_numeric": "840", "smallest_denomination": 1 } config.register_currency = { "priority": 3, "iso_code": "EUR", "name": "Euro", "symbol": "€", "alternate_symbols": [], "subunit": "Cent", "subunit_to_unit": 100, "symbol_first": true, "html_entity": "&#x20AC;", "decimal_mark": ",", "thousands_separator": ".", "iso_numeric": "978", "smallest_denomination": 1 } # Set default money format globally. # Default value is nil meaning "ignore this option". # Example: # # config.default_format = { # :no_cents_if_whole => nil, # :symbol => nil, # :sign_before_symbol => nil # } # Set default raise_error_on_money_parsing option # It will be raise error if assigned different currency # The default value is false # # Example: # config.raise_error_on_money_parsing = false end _form.html.erb <%= f.collection_select :category_id, Category.all, :id, :name, {prompt: "Choose a category"} %> <!-- The above code loop assigns a category_id to each event --> <%= f.input :image, as: :file, label: 'Image' %> <%= f.input :title, label: 'Event Title' %> <label>Location</label><%= f.text_field :location, id: 'geocomplete' %></br> <label>Date</label><%= f.text_field :date, label: 'Date', id: 'datepicker' %> <%= f.input :time, label: 'Time' %> <%= f.input :description, label: 'Description' %> <label>Number of spaces available</label><%= f.text_field :number_of_spaces, label: 'Number of spaces' %> <%= f.input :is_free, label: 'Tick box if Event is free of charge' %> <%= f.input :currency, :collection => [['£GBP - British Pounds',1],['$USD - US Dollars',2],['€EUR - Euros',3]] %> <%= f.input :price, label: 'Cost per person (leave blank if free of charge)' %> <%= f.input :organised_by, label: 'Organised by' %> <%= f.input :url, label: "Link to Organiser site" %> <%= f.button :submit, label: 'Submit' %> <% end %> show.html.erb <%= image_tag @event.image.url %> <h1><%= @event.title %></h1> <p>Location </p> <p><%= @event.location %></p> <p>Date</p> <p><%= @event.date.strftime('%A, %d %b %Y') %></p> <p>Time</p> <p><%= @event.time.strftime('%l:%M %p') %></p> <!-- above expresses date and time as per UK expectations --> <p>More details</p> <p><%= @event.description %></p> <p>Number of Spaces available</p> <p><%= @event.number_of_spaces %></p> <% if @event.is_free?

Capistrano Multiple Deploy Stages Posted: 28 Apr 2016 04:51 AM PDT I have a Rails app and I would like to use Capistrano to deploy two versions: production and staging. On my deploy.rb file I have: set :stages, ['staging', 'production'] Then how can I use two paths without overriding them? set :deploy_to, '/home/deploy/Sites/staging/myname' set :deploy_to, '/home/deploy/Sites/production/myname' I've seen this answer but I'd like to keep the command line clean.

Update associated 'latest' model Posted: 28 Apr 2016 05:55 AM PDT I have the following two models in my application, Product and Price A Product describes the product (name, description, etc.) and thePrice has a value, first_seen_at (datetime) and last_seen_at (datetime). A Product has_many Prices. The idea is that when a the price of a product changes, the latest Price record is updated: If the value of the new price is the same as the existing price, last_seen_at is updated If the value of the new price is different to the existing price, a new Price record is created with the new details I want to be able to access the latest price of a product, so currently use product.prices.last.value where product is any given product from the database Is there a better way of achieving this? To add a price to the database, I'm currently performing the following actions: Find product in database Find latest price for that product Check for difference in price Either update price record or create a new price record I know I could store the latest_price in the Product record, but the data would then be duplicated...

EmberJS - how to restructure embedded models? Posted: 28 Apr 2016 06:27 AM PDT Note: Using Ember Rails 0.18.2 and ember-source 1.12.1 I have inherited an Ember app that has a strange function. I am new to Ember so maybe this is normal, but I find it odd. There are 3 models: Parents Games Comments When a Parent views a game the url looks like this: /<parent slug>/games/<game_id> (the slug is just a unique id for the parent). At this url there is a template that has this code: {{#unless commentsOpen}} {{#link-to 'comments' class="Button easyButton"}}Chat with parents in your pod{{/link-to}} {{/unless}} {{outlet}} Clicking the above button then changes the url to this: /<parent slug>/games/<game_id>/comments Then all the comments appear for that game. I need to remove that button from the view and have Comments display automatically for each Game. The API is Rails, and I can already change the API endpoint to return all the Comments at the same time a Game is requested (as an embedded array of objects). But what do I replace {{outlet}} with? Because my understanding is that {{outlet}} is delegating to the Comments template due to this route: App.CommentsRoute = Ember.Route.extend model: -> return this.store.find('comment', { game: @modelFor('game').get('id') parent: @modelFor('parent').get('slug') }).then( (models) -> models.toArray() ) I believe I need to remove that route and make the Comments an embedded object inside the Game model. Do I then just replace outlet with something like: {{#each comment in Game}} <div class="commentItem"> <div class="commentItem-author">{{comment.parent_name}}</div> <div class="commentItem-body">{{comment.body}}</div> </div> {{each}}

how to add a folder (which name has a 'dot' inside) to rails javascript or stylesheet manifest? Posted: 28 Apr 2016 04:19 AM PDT Trying to add 'fullpage.js' (bower component & folder name) to Rails manifest 'application.js' but fail with the 'dot'. I know it can be workaround by changing the folder name to 'fullpage' manually but it will cause problem when deploy to heroku. Is there a way to make 'require_tree' accept folder name with 'dot'? // require_tree . // //= require_tree ./"fullpage.js"

How to store data in Ruby most effectively? Posted: 28 Apr 2016 05:08 AM PDT I am pulling data from multiple sources in ruby, like so : <div class="News"> <% @subject.customersAssociation.each do |customer| %> <% customer.websitesAssociation.each do |website| %> <% website.newsAssociation.sorted_by(field('DATE')).each do |news| %> <ul> <li>..Print data from |customer|... </li> <li>..Print data from |website|... </li> <li>..Print data from |news|... </li> </ul> <% end %> <% end %> <% end %> I would like to change how I am structuring this code so instead of printing the data, I store it, for iterating over, and sorting, later. So essentially, I would like to define an object or structure where I can save the data. The problem is that I need to do this on the fly - I only have access to the code in this one particular area. I cannot create a separate class etc. I've tried a number of solutions, such as creating objects on the fly like so : <% testobj = testobj.create(name: "David", occupation: "Code Artist") %> (and instead of "David" accessing variables in the customer/website/news Entities.) Does anyone know of an elegant/simple possible solution here?

Creating policy for complex associations Posted: 28 Apr 2016 04:04 AM PDT I am building a rails app where a User can be the owner of an account by being the "admin" of the account. But an Account also has_many Userswho are the "employees of the account. I expressed this relationship in my models like this : class Account < ActiveRecord::Base has_many :users, through: :hotels, dependent: :destroy belongs_to :admin, class_name: "User", foreign_key: "admin_user_id" end class User < ActiveRecord::Base belongs_to :account has_one :created_account, class_name: "Account", foreign_key: "admin_user_id", inverse_of: :admin, dependent: :destroy end I have a problem with my action show in UserController. I am using Pundit gem for policies and I only want two type of users to be able to access this action : - the admin of the account and the actual user related to the profile requested Problem is I dont know how to express that within my Pundit UserPolicy. At first I tried this def show? (user && (record == user)) || (user && (record.account.admin == user)) end The first part of the statement works : user && (record == user)) but the second part won't work because if the user is the admin of the account he won't have an account_id, it will be the account that will have an admin_user_id referring to him. I dont see how I can express this using Pundit as I only send to the UserPolicy the User instance and not the Account instance : def show authorize @user end Am I doing something wrong in my associations ? Should I not use Pundit for this particular occurence and set up my own policy ?

How can I access to related object by string field name in Ruby on Rails ActiveRecord? Posted: 28 Apr 2016 04:15 AM PDT Usually when we need to use ActiveRecord related object, we write such code: main_object.related_object Where main_object is instance of MainObject class and related_object is instance of RelatedObject that connected to MainObject via related_object_id field: class MainObject < ActiveRecord::Base :has_one => :related_object end class RelatedObject < ActiveRecord::Base :belongs_to => :main_object end Count of relations might be difference and more than one. Also my task supposes custom queries where I don't know which one relation will be used. So, I want to get related object via its name, eg: main_object.relations['related_object'] Is it possible in Ruby on Rails ActiveRecord?

bootstrap not binding with dynamically rendered html via erb Posted: 28 Apr 2016 03:26 AM PDT I am working on a Rails app with Bootstrap. In one of my views I make use of 'tabs': <ul class="nav nav-tabs" id="myTab" role="tablist"> <li class="nav-item"> <a class="nav-link active" data-toggle="tab" href="#home" role="tab" aria-controls="home">Home</a> </li> <li class="nav-item"> <a class="nav-link" data-toggle="tab" href="#profile" role="tab" aria-controls="profile">Profile</a> </li> <li class="nav-item"> <a class="nav-link" data-toggle="tab" href="#messages" role="tab" aria-controls="messages">Messages</a> </li> </ul> <div class="tab-content"> <div class="tab-pane active" id="home" role="tabpanel">...</div> <div class="tab-pane" id="profile" role="tabpanel">...</div> <div class="tab-pane" id="messages" role="tabpanel">...</div> </div> This works fine if its hard coded HTML. When I dynamically add an extra 'li' in "nav-tabs" item: <% if @customer.profiles.present? %> <% @customer.profiles.each_with_index do |profile,index| %> <li class="nav-item"> <a class="nav-link" data-toggle="tab" href="#profile<%=index%>" role="tab"> profile-<%=index%> </a> </li> <% end %> <% end %> and 'div' in "tab-content" with both a unique number: <% if @customer.profiles.present? %> <% @customer.profiles.each do |profile,index| %> <div class="tab-pane" id="profile<%=index%>" role="tabpanel"> <%= render :partial => 'profiles/homes_pane' , :locals => { :profile => profile} %> </div> <% end %> <% end %> added in the 'href' and 'id', the tabs are not working anymore. So it seems that Bootstrap is not binding the javascript to the dynamically generated HTML elements. Am I doing something wrong or do I need a workaround. Any suggestions are welcome. best regards, Martijn

List all Mongoid models in Rails console Posted: 27 Apr 2016 06:52 AM PDT I want to list all the models which have a respective collection in my mongodb database? I'm using mongoid gem for for MongoDB. I would try something like this ActiveRecord::Base.send :subclasses which works fine, but I'm not using ActiveRecord.

html.erb - How to fill last row with empty divs Posted: 27 Apr 2016 06:55 AM PDT I have a view in my rails app that is an image gallery. The view looks like this: view.html.erb <div class="photo-row"> <% @item.item_images.each_with_index do |image, index| %> <% if (index % 3 == 0) && (index != 0) %> </div><div class="photo-row"> <% end %> <div class="photo-wrapper"> <a class="fancybox" rel="group" href="<%= image.picture.large.url %>"><img class="pending-photo" src="<%= image.picture.small.url %>" alt="" /></a> </div> <% end %> </div> As you can see the row will fill up with three images and then create a new row. For my alignment I need the last non-full row to be filled with with 3 photo-wrapper divs. For example if an @item has 7 item_images I need there to be three rows. The first two are full and the last should have 1 with the image and 2 empty wrappers. How can I achieve this?

Application.rb override base Ruby class Posted: 27 Apr 2016 06:49 AM PDT I have a RoR application that is doing the following in its application.rb Digest::MD5 = Digest::SHA256 This in turn ensures that everytime anyone invokes Digest::MD5 that it will instead replace the result with a Digest::SHA256. I believe this will have some unintended consequences, such as runtime issues that are hard to debug. Is there any alternative to this approach or is this sound?

How to get gcm registration token using gcm gem in ruby on rails? Posted: 27 Apr 2016 06:32 AM PDT I am trying to implement web push notifications in my rails app using gcm gem but i am not able to get the registration token provided by the user to store it into db for sending notification. Is there any solution to get the registration id?

rails ajax request returning not found but controller function exists Posted: 27 Apr 2016 06:27 AM PDT I've got some problems with an ajax function. I got an 500er error from server. ajax function looks like this: $.ajax({ type: "POST", url: "<%= url_for(:controller => "movies", :action => "test") %>", data: {inputtag: tag } }) in my movies controller I've got this function # Fügt dem Video einen Tag hinzu def test @tag = Tag.new if request.post? @tag.update_attributes(params[:inputtag]) if @tag.save redirect_to :back else redirect_to :back end end end So I don't know Why I got this error http://lvh.me/movies/test 500 (Internal Server Error)

How can chaining one method onto another change the original method Posted: 27 Apr 2016 06:33 AM PDT The easiest way to explain this conundrum is with an example: Say I have two Mongoid models which are related via a has_many relationship: A Blog post class Post include Mongoid::Document field :body, type: String has_many :comments end and it's comments class Comment include Mongoid::Document field :text, type: String belongs_to :post end Now I create a Post which has two comments in IRB, and I attempt to load them via the relationship. I have some DB logging enabled so I can see when the query is made: post.comments #=> 2016-04-27 13:51:52.144 [DEBUG MONGODB | localhost:27017 | test.find | STARTED | {"find"=>"comments", "filter"=>{"post_id"=>BSON::ObjectId('571f315e5a4e491a6be39e02')}}] 2016-04-27 13:51:52.150 [DEBUG MONGODB | localhost:27017 | test.find | SUCCEEDED | 0.000492643s] => [#<Comment _id: 571f315e5a4e491a6be39e03, text: 'great post' >, #<Comment _id: 571f315e5a4e491a6be39e12, text: 'this!' >] So the comments are loaded from the DB and returned as a Mongoid::Relations::Targets::Enumerable class, which looks like an array, and it contains the two comments. Now when I open a fresh IRB console, and take a look at the criteria used to load these comments using the criteria attribute of the Mongoid::Relations::Targets::Enumerable class instance post.comments, I get this output: post.comments.criteria #=> => #<Mongoid::Criteria selector: {"post_id"=>BSON::ObjectId('571f315e5a4e491a6be39e02')} options: {} class: Comment embedded: false> How come no DB requests is made in this example? It's not a caching problem as I opened a new IRB console. How can chaining criteria onto post.comments change what the .comments method does? I took a look through Mongoid's implementation of the Mongoid::Relations::Targets::Enumerable class (source on Github), but couldn't find any clues to how it works.

Rails: Searchform for Tags Posted: 27 Apr 2016 06:47 AM PDT I build a simple tagging system into my webapp (I've followed these steps: http://www.sitepoint.com/tagging-scratch-rails/) So, now it's working fine that people can click on a Tag e.g. Dogs and they are going to "app.com/search/dogs". But, now the people should also search for tags by using a form input field. At the moment I've tried this: <%= form_tag('search', method: 'get', controller: 'static', action: 'home') do %> <%= text_field_tag :tag, params[:tag], placeholder: "Search Posts" %> <%= submit_tag("Search") %> <% end %> That brings the user to: "app.com/search/?utf8=✓&tag=Dogs&commit=Search" and that's not working. Is there a way to achieve the other logic? Here some (maybe) interesting code samples: routes.rb # search by tags get 'search/:tag', to: 'static#home', as: "search" post.rb def self.tagged_with(name) Tag.find_by_name!(name).posts end static_controller.rb def home if params[:tag] @posts = Post.tagged_with(params[:tag]) else @posts = Post.all end end posts_helper.rb def tag_links(tags) tags.split(",").map{|tag| link_to tag.strip, search_path(tag.strip) }.join(" ") end Sorry, I'm a real beginner :) Thank you in advance!

How to lint factories immediately with guard and factory girl? Posted: 27 Apr 2016 06:07 AM PDT What do I need tu put in my Guardfile (in a Rails application with RSpec and FactoryGirl) to lint all my factories every time I change a factory? I know that it is possible to run all models spec, accordingly to this question: Using guard-rspec with factory-girl-rails, but I want to only lint them all. I tried to do this in Guardfile, but it was not enough: watch(%r{^spec/factories/(.+)\.rb$}) { FactoryGirl.lint } Thanks in advance.

Aptana 3 - Rails debugger not doing anything Posted: 27 Apr 2016 06:10 AM PDT When invoking "Debug Server" nothing happens at all, no error messages, nothing. Also, nothing happens when opening a page in the browser that has breakpoints set in it. In case i invoke "Debug as Ruby Application" i get the following exception: Fast Debugger (ruby-debug-ide 0.6.1.beta2, debase 0.2.1, file filtering is supported) listens on 127.0.0.1:57291 Uncaught exception: uninitialized constant ApplicationController /home/jobmob/dev/jm10/app/controllers/sessions_controller.rb:1:in `<top (required)>' /home/jobmob/.rbenv/versions/2.3.0/bin/rdebug-ide:23:in `load' /home/jobmob/.rbenv/versions/2.3.0/bin/rdebug-ide:23:in `<main>' But i think this is not the right way to debug a Rails appliation anyways, is it?

Phoenix/Elixir vs Rails - full stack benchmark? [on hold] Posted: 27 Apr 2016 06:32 AM PDT I'm new to Elixir/Phoenix and looking for full stack benchmarks comparisons with Rails. I found this post (but it doesn't hit the database) http://www.littlelines.com/blog/2014/07/08/elixir-vs-ruby-showdown-phoenix-vs-rails/ A Blog index page would be fine (with variable posts list) - as long as it hits the database. Thanks for any input!

Stop rails url_helper from requesting a lot of unnecessary objects from database Posted: 27 Apr 2016 05:52 AM PDT I'm creating a large xml output using rails and there are a lot of urls generated by rails. There are so called items and enclosures. Every item may have one enclosure. So I'm using has_one and belongs_to relation in my model. I'm using enclosure_url(item.enclosure, format: :json) for generating the url. What I expect: Rails should generate the url based on the id which is stored in the items table. What now happens is, that rails is fetching each single enclosure from the database which is slowing down my system. Enclosure Load (2.6ms) SELECT "enclosures".* FROM "enclosures" WHERE "enclosures"."id" = ? LIMIT 1 [["id", 11107]] Enclosure Load (3.1ms) SELECT "enclosures".* FROM "enclosures" WHERE "enclosures"."id" = ? LIMIT 1 [["id", 11108]] Enclosure Load (0.7ms) SELECT "enclosures".* FROM "enclosures" WHERE "enclosures"."id" = ? LIMIT 1 [["id", 11109]] Enclosure Load (1.5ms) SELECT "enclosures".* FROM "enclosures" WHERE "enclosures"."id" = ?

You cannot use a Stripe token more than once Posted: 27 Apr 2016 06:24 AM PDT I cannot seem to charge a card then create a customer on the fly in Rails 4. def charge token = params[:stripeToken] # can only be used once. begin charge = Stripe::Charge.create( :amount => 5000, :currency => "gbp", :source => token, :description => "Example charge" ) rescue Stripe::CardError => e # The card has been declined end if current_user.stripeid == nil customer = Stripe::Customer.create(card: token, ...) current_user.stripeid = customer.id current_user.save end end I have looked at this but there is no such thing as token.id as token is just a String.

Has many through doesn't persist Posted: 27 Apr 2016 05:27 AM PDT I have a question about the Has Many Through relationship. I have 3 models : Artist, Skill, and Mastery skill.rb class Skill < ActiveRecord::Base has_many :masteries has_many :artists, through: :masteries end mastery.rb class Mastery < ActiveRecord::Base belongs_to :artist belongs_to :skill end artist.rb class Artist < ActiveRecord::Base has_many :masteries has_many :skills, through: :masteries end Everytime I try to attach a skill to an Artist, using artist.skills << skill, a mastery is created, but the artist_id is nil. Same thing the other way around. skill.artists << artist gives me a Mastery with a nil skill_id. Does this mean that I have to execute both every time ? Or did I miss something ?

Writing to .zip file from binary data Posted: 27 Apr 2016 06:48 AM PDT I am trying to write a rails test (Using Capybara & Poltergeist) to test .zip file download functionality. I have the binary data of a .zip file being returned from an XHR request and I am hoping to write this data into a .zip file locally and carry out further tests from there. The following method emulates a click on a button which, when in-app, returns a zip file of all the files that have been selected: # Perform XHR def download_file(link) page.execute_script("window.downloadFile = function(){ var url = window.location.protocol + '//' + window.location.host + '#{link}'; return getFile(url); }") page.execute_script("window.getFile = function(url){ var xhr = new XMLHttpRequest(); xhr.open('GET', url, false); xhr.responseType = 'blob'; xhr.send(); return xhr.response; }") begin file = page.evaluate_script('downloadFile()') rescue raise "Error during XHR. Is url valid?" end file end I am trying to write the response to file here: file = download_file(url) file_path = "#{Rails.root}/tmp/files/download.zip" File.open(file_path, 'wb'){ |f| f.write file } When trying to unzip the resulting file using unzip tmp/files/download.zip I'm given the following response: Archive: tmp/files/download.zip caution: zipfile comment truncated error [tmp/files/download.zip]: missing 3182550208 bytes in zipfile (attempting to process anyway) error [tmp/files/download.zip]: start of central directory not found; zipfile corrupt.

Ruby on rails. Add facebook.com/ to URL if not present Posted: 27 Apr 2016 05:29 AM PDT my users have the option to add their website, facebook and twitter URL's to their profile. I want to let them enter either the full URL (http://www.facebook.com/USERNAME) or part of the URL Eg. www.facebook.com/USERNAME or just USERNAME, and then have the https://facebook.com/ added automatically if needed. I want the http:// as then the entered URL will link directly to their website/facebook etc. For the website URL I have: before_validation :add_url_protocol def add_url_protocol if self.website && !url_protocol_present? self.website = "http://#{self.website}" end end def url_protocol_present? self.website[/\Ahttp:\/\//] || self.website[/\Ahttps:\/\//] end There is then further regex validation. This works fine. The thing is I don't have much of an idea about regex and I am unsure on how to add the facebook.com/ part to this before_validation code. Any help would be greatly appreciated, thanks. UPDATE: def add_url_protocol if self.website && !url_protocol_present? self.website = "http://#{self.website}" end if self.facebook && !url_facebook_present? self.facebook = "http://facebook.com/#{self.facebook}" end end This almost works. If a user inputs USERNAME then the output is good. If the user inputs www.facebook.com/USERNAME then the ouput becomes http://facebook.com/www.facebook.com/USERNAME

Let users join multiple leagues (groups) and switch between them Posted: 27 Apr 2016 05:13 AM PDT I'm creating an application to store played FIFA Games and build a private leaderboard with friends. I managed to add a user to a league (private group) but now I want to let users join multiple leagues and easily switch between them. I've added a league_id to games and to users. When loading the leaderboard I'm only showing the users that match current_user.league_id and for the wins and losses I'm only counting the games with that match current_user.league_id. This works perfectly, however a user should be able to join annother league and switch easily between them. I was thinking creating another field to users that stores a collection of all joined leagues and add an action to change the active_league_id. Can someone point me in the right direction here? class User < ActiveRecord::Base devise :registerable, :confirmable devise :omniauthable, :omniauth_providers => [:facebook] #RELATIONS SINGLE GAMES has_many :home_games, class_name: 'Game', foreign_key: 'home_team_user_id' has_many :away_games, class_name: 'Game', foreign_key: 'away_team_user_id' #RELATIONS MULTI GAMES has_many :first_home_games, class_name: "Multiplayergame", foreign_key: "home_team_first_user_id" has_many :second_home_games, class_name: "Multiplayergamer", foreign_key: "home_team_second_user_id" has_many :first_away_games, class_name: "Multiplayergame", foreign_key: "away_team_first_user_id" has_many :second_away_games, class_name: "Multiplayergame", foreign_key: "away_team_second_user_id" #RELATIES SCORE CLASSEREN SINGLE GAMES has_many :wins, class_name: 'Game', foreign_key: 'winner_id' has_many :losses, class_name: 'Game', foreign_key: 'loser_id' has_many :bonusses, class_name: 'Game', foreign_key: 'bonus_id' has_many :loserbonusses, class_name: 'Game', foreign_key: 'bonus_loser_id' has_many :firstdraws, class_name: 'Game', foreign_key: 'first_draw_id' has_many :seconddraws, class_name: 'Game', foreign_key: 'second_draw_id' #RELATIES SCORE CLASSEREN MULTI GAMES has_many :firstwins, class_name: 'Multiplayergame', foreign_key: 'winner_first_id' has_many :secondwins, class_name: 'Multiplayergame', foreign_key: 'winner_second_id' has_many :firstlosses, class_name: 'Multiplayergame', foreign_key: 'loser_first_id' has_many :secondlosses, class_name: 'Multiplayergame', foreign_key: 'loser_second_id' has_many :firstbonusses, class_name: 'Multiplayergame', foreign_key: 'bonus_first_id' has_many :secondbonusses, class_name: 'Multiplayergame', foreign_key: 'bonus_second_id' has_many :firstloserbonusses, class_name: 'Multiplayergame', foreign_key: 'bonus_first_loser_id' has_many :secondloserbonusses, class_name: 'Multiplayergame', foreign_key: 'bonus_second_loser_id' has_many :firstmultidraws, class_name: 'Multiplayergame', foreign_key: 'first_multidraw_id' has_many :secondmultidraws, class_name: 'Multiplayergame', foreign_key: 'second_multidraw_id' has_many :thirdmultidraws, class_name: 'Multiplayergame', foreign_key: 'third_multidraw_id' has_many :fourthmultidraws, class_name: 'Multiplayergame', foreign_key: 'fourth_multidraw_id' belongs_to :league has_one :league_admin, class_name: 'League', foreign_key: 'league_admin_id' ############################################################################################## ### TOTAL WINS CURRENT LEAGUE SINGLE PLAYER def current_league_wins wins.where(:league_id => self.league_id).count end #### TOTAL LOSSES CURRENT LEAGUE SINGLE PLAYER def current_league_losses losses.where(:league_id => self.league_id).count end #### TOTAL DRAWS CURRENT LEAGUE SINGLE PLAYER def draws firstdraws.where(:league_id => self.league_id).count + seconddraws.where(:league_id => self.league_id).count end ##################################################################################################### #### TOTAL WINS CURRENT LEAGUE MULTIPLAYER def current_league_multi_wins firstwins.where(:league_id => self.league_id).count + secondwins.where(:league_id => self.league_id).count end #### TOTAL LOSSES CURRENT LEAGUE MULTIPLAYER def current_league_multi_losses firstlosses.where(:league_id => self.league_id).count + secondlosses.where(:league_id => self.league_id).count end #### TOTAL DRAWS CURRENT LEAGUE MULTIPLAYER def multidraws firstmultidraws.where(:league_id => self.league_id).count + secondmultidraws.where(:league_id => self.league_id).count + thirdmultidraws.where(:league_id => self.league_id).count + fourthmultidraws.where(:league_id => self.league_id).count end Controller scoreboard: class ScoreboardController < ApplicationController before_action :authenticate_user! #LAAD ALLE USERS GERANSCHIKT VOLGENS SCORE def index @users = User.where(:league_id => current_user.league_id).sort_by(&:score).reverse end end What I need to achieve is that users can easily switch between the joined leagues and that if a user changes leagues he still appears in all the leaderboards. If a user changes league now he's not in that leaderboard any more until he rejoines, wich is normal since his league_id changes.

Rails Omniauth - multiple social logins for same user Posted: 27 Apr 2016 04:11 AM PDT I've set up my Rails app to incorporate both Facebook and Twitter sign-in options and both work fine. However, when logging in for first time they create a new user rather than log in as the same user. How do I set up my app so one user can have multiple log in options - facebook, twitter or AN Other?

Rails: callback in controller to change attribute from true to false in database Posted: 27 Apr 2016 06:22 AM PDT so I'm testing how to make a multiplayer Tic Tac Toe game, and for this I made a User model and a Game model, and by a has_many_through association they have various game_users. Each game has an attribute: "seeking_players", that by default is true. When I create a new game_user, I check if they're exists a game with the seeking_players attribute set to true. If such a game exists, I make a new game_user for this game and I want to set this attribute to false. But whatever I try, I can't seem to change this attribute. So, my question: what's wrong with this code: EDIT: this is the new code after suggestions from @Малъ Скрылевъ class GamesController < ApplicationController before_action :logged_in_user before_action :assign_game, only: [:new] after_action :update_seeking_players, only: [:assign_game] def new @game = assign_game @game.game_users.create(user: current_user) redirect_to game_url(id: @game.id) end def game end private def assign_game @game = Game.find_by_seeking_players(true) || Game.create end def update_seeking_players if @game.game_users.size == 2 @game.update(seeking_players: false) end end end PS: I also tried changing this "seeking players" attribute in the Game model (with a callback "after_add"), which is maybe a more appropriate place? But I really can't figure out how to do this... UPDATE: these are the Game & GameUser model class Game < ActiveRecord::Base has_many :game_users has_many :users, :through => :game_users end class GameUser < ActiveRecord::Base belongs_to :game belongs_to :user validates :game_id, presence: true validates :user_id, presence: true end UPDATE 2 the migration for seeking_players class AddSeekingPlayersWithIndexToGames < ActiveRecord::Migration def change add_column :games, :seeking_players, :boolean, :default => true add_index :games, :seeking_players end end

Getting OAuthException 191 Posted: 27 Apr 2016 04:31 AM PDT I am getting this error when logging through Facebook on a Ruby on Rails app. What I want is when login is OK, redirect to https://hacker-news-alexvilarrubla.c9users.io/submissions but I don't exactly know how to do this.

Can I use oracle_enhanced adapter in vanity gem for AB Testing? Posted: 27 Apr 2016 03:34 AM PDT For my production database, I am using oracle_enhanced adapter. Is this supported by vanity gem? From https://github.com/assaf/vanity, it says: "Vanity supports multiple SQL stores (like MySQL, MariaDB, Postgres, Sqlite, etc.) using ActiveRecord, which is built into Rails". I am not sure if this etc includes Oracle. I tried using the below in my config/vanity.yml: production: adapter: oracle_enhanced host: mydb.XXX.com username: XXX password: XXX port: XXXX database: mydb But what I get is the error message below: Could not find oracle_enhanced in your load path (RuntimeError) My config/database.yml is actually using adapter: oracle_enhanced. Any advice what I'm missing?

Is there a way do export a database in a rails app to excel Posted: 27 Apr 2016 04:56 AM PDT I'm being faced with a task of having a button on my rails application which basically exports the entire sqlite database to an excel file. So that the client can make pretty little graphs and do excel like things with the information. I have done a cheeky google search trying to find a gem but I have literally 0 clue how they work and if they actually do what I want them to do. I have tried using the Axlsx gem, but it didn't work. I know I'm probably going to get a lot of hate on here because its not your orthodox question, but I'm at wits end with this database. Any ideas? Cheers

Can I allow certain views only to be rendered in iframes? Posted: 27 Apr 2016 04:49 AM PDT I got an application that serves widgets inside iframes of other websites. So far so good but how can I allow these widgets views only to be loaded inside an iframe and not directly? This should work <iframe src="http://www.example.com/widgets/example"> But typing in http://www.example.com/widgets/example directly into a browser shouldn't be allowed. What is or is there a best way to achieve this in rails?
