| 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? |

| 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? |

| 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! |

| 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? |

| 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. If I change the method to generic, I get Net::LDAP::AuthMethodUnsupportedError in ObservationsController#index Unsupported auth method (generic) Rails.root: C:/Users/cmendla/RubymineProjects/employee_observations Application Trace | Framework Trace | Full Trace app/controllers/observations_controller.rb:61:in `index'
If I test using ldp.exe with the same credentials I'm using above using generic, I get res = ldap_bind_s(ld, NULL, &NtAuthIdentity, 1158); // v.3 {NtAuthIdentity: User='railsauthentication'; Pwd= <unavailable>; domain = 'ccttapes1.com'.} Authenticated as dn:'railsauthentication'.
If I switch to simple, I get a failure to bind of res = ldap_simple_bind_s(ld, 'railsauthentication', <unavailable>); // v.3 Error <49>: ldap_simple_bind_s() failed: Invalid Credentials Server error: 80090308: LdapErr: DSID-0C0903A9, comment: AcceptSecurityContext error, data 52e, v1db1
Apparently my ldap server is looking for the method being generic but net-ldap will not allow me to set the method to generic |

| 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

| 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.

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}}

I know it can be workaround by changing the folder name to 'fullpage' manually but it will cause problem when deploy to heroku.

| 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 |
