Rails more than one skip_before_action Posted: 17 Jul 2016 07:51 AM PDT I want to do more than one skip_bevore_action tried this: skip_before_action :user_logged_in, :user_is_provider, only: [:impressum, :agb, :help, :privacy] but the :user_is_provider function isn't called yet. The function is in application_controller.rb Thanks

Getting associated model attributes using strings Posted: 17 Jul 2016 07:45 AM PDT I am building a custom method and i want to access attributes by using strings. for example @search["attribute_name"] While this works, when i try to get associated attribute values its not working. example: @search["category_id"]["name"] can someone point me in the right direction here?

Proper use of polymorphic association for reports Posted: 17 Jul 2016 07:42 AM PDT I have a Category model that has_many Link and Text posts, and those posts have many Reports. How should I best set up my models/schema to retrieve all reports for the category by using @category.reports? I based this on the example in the docs: class Category < ActiveRecord::Base has_many :link_posts, class_name: "Link" has_many :text_posts, class_name: "Text" end class Link < ActiveRecord::Base belongs_to :category has_many :reports, as: :reportable end class Text < ActiveRecord::Base belongs_to :category has_many :reports, as: :reportable end class Report < ActiveRecord::Base belongs_to :reportable, polymorphic: true end If I do something like that I would have to use a hacky method to retrieve them: class Category < ActiveRecord::Base def reports reports = [] reports << Report.where(reportable: self.link_posts.to_a) reports << Report.where(reportable: self.text_posts.to_a) reports end end What's the proper way?

Passing custom arguments to Sidetiq Posted: 17 Jul 2016 07:32 AM PDT I have a Rails app that requires the user to pass in input that defines how frequently an action is scheduled (e.g one month, three months, six months, etc.) I'm using Sidekiq to run backup jobs, and integrated Sidetiq for the scheduling. As it turns out (something I realized only after integrating it fully), Sidetiq has problems with recurring tasks that initially require custom input. It will run fine the first time, but when it comes up to run three months later, the arguments the method has are (time_last_run, time_of_next_run) and this is a problem for me because I need some user details passed into the recurring action. This is discussed by Sidetiq's author in this issue from a few years ago: https://github.com/tobiassvn/sidetiq/issues/37 This leaves me rather lost. This is my first Rails app, and I'm not sure how else to perform recurring background tasks with user input. As you can see, the Sidetiq issue still hasn't been resolved, and I'm not sure of any valid alternatives. Does anyone know how I can write a workaround for this? Put another way, how else could I implement this functionality (with or without Sidetiq)?

rspec tests in docker showing database transactions Posted: 17 Jul 2016 07:20 AM PDT I'm developing a rails app with docker compose and 4 different services: the app, postgres, redis and sidekiq. my problem is that docker compose run app rake spec puts all database transactions to stdout, not just the test output. as a result they are basically unintelligible. I've tried running this with docker-compose run e RAILS_ENV=test app rake spec and i'm open to the possibility that something else in my spec config that has changed since i started dockerizing- but i just checked out my pre-docker commit and specs ran fine with regular output.

Ruby on Rails, Select Users with age range from Active Record Posted: 17 Jul 2016 07:11 AM PDT User.rb # Attributes # (..) # birthdate (string) # format "mm/yyyy" def age dob = self.birthdate.to_date now = Time.now.utc.to_date now.year - dob.year - ((now.month > dob.month || (now.month == dob.month && now.day >= dob.day)) ? 0 : 1) end In the console: irb(main):002:0> current_user.age => 7 I'd be able to do the following: age_range = "25-65" User.where(:age => between age_range) I'm stuck at the point how to get the value from age (class method) into the where call

Unicorn, can't restart: "rack and Rack::Builder must be available for processing config.ru" Posted: 17 Jul 2016 06:52 AM PDT I have an Ubuntu 14.04 server with nginx and unicorn. I have deployed a Rails application with capistrano to /home/rails/myapp. When trying to restart unicorn with sudo service unicorn restart I get the following: * Restarting Unicorn web server unicorn rack not available, functionality reduced rack and Rack::Builder must be available for processing config.ru I'm getting a 502 from nginx when trying to access the site in my browser. Here's my /etc/default/unicorn file: # Change paramentres below to appropriate values and set CONFIGURED to yes.

can we manage multiple shopify key in one application? Posted: 17 Jul 2016 06:50 AM PDT We want to use multiple Shopify API keys in one shopify rails application and switch these API key run time. We are working on to increase API call by help to multiple API calls. Because of each API key have some limitation calls like 40 call at time.

Searchkick - how to update mappings and settings (rails) Posted: 17 Jul 2016 06:45 AM PDT I have a rails application and around 90k products in my database. I updated the model settings and mappings and need to update these in elasticsearch. When I call Product.reindex, I get a timeout error (Faraday::TimeoutError: Net::ReadTimeout) after 10seconds (I am using also batch_size: 100). When I start reindexing each product using find_in_batches method, it will reindex all products, but will not update settings and mappings. Is there any other way (maybe simpler) how can I only update settings and mappings of my index without reindexing the records itself (or anything else that would work and would not throw timeout error)? Here is the model configuration: searchkick batch_size: 100, settings: { number_of_shards: 1, analysis: { filter: { hunspell_CZ: { type: 'hunspell', locale: 'cs_CZ', dedup: true, recursion_level: 0 }, czechStemmer: { type: 'stemmer', name: 'czech' }, # customWordDelimiter: { # type: 'word_delimiter', # generate_word_parts: true, # generate_number_parts: true, # catenate_words: true, # catenate_numbers: true, # catenate_all: true, # split_on_case_change: true, # preserve_original: true, # split_on_numerics: true, # stem_english_possessive: false # }, customUnique: { type: 'unique', only_on_same_position: false }, czechDucetSort: { type: 'icu_collation', language: 'cs' } }, analyzer: { myFulltextAnalyzer: { type: 'custom', tokenizer: 'standard', filter: ['lowercase', 'hunspell_CZ', 'czechStemmer', 'customUnique', 'icu_folding'],#'customWordDelimiter', char_filter: ['html_strip'] }, ducet_sort: { tokenizer: 'keyword', filter: ['czechDucetSort'] } } } }, text_middle: [ :cs_product, :ma_product, :en_product, :cs_description, :en_description, :ma_description ], index_name: "products_v2", merge_mappings: true, mappings: { product: { properties: { cs_product: { type: "string", analyzer: "myFulltextAnalyzer", index: "analyzed", fields: { raw: { type: "string", analyzer: "ducet_sort", index: "not_analyzed" } } }, en_product: { type: "string", analyzer: "myFulltextAnalyzer", index: "analyzed", fields: { raw: { type: "string", analyzer: "ducet_sort", index: "not_analyzed" } } }, ma_product: { type: "string", analyzer: "myFulltextAnalyzer", index: "analyzed", fields: { raw: { type: "string", analyzer: "ducet_sort", index: "not_analyzed" } } }, cs_description: {type: "string", analyzer: "myFulltextAnalyzer", index: "analyzed"}, en_description: {type: "string", analyzer: "myFulltextAnalyzer", index: "analyzed"}, ma_description: {type: "string", analyzer: "myFulltextAnalyzer", index: "analyzed"} } } }

Why is my RSpec not loading Devise::Test::ControllerHelpers? Posted: 17 Jul 2016 07:49 AM PDT I'm using Rails 5, and Devise 3.5.1. Going through a nice (older) book about creating/testing an API, which uses Devise authentication. It was written before Rails 5, so I chose not to use the new api-only version. Here's my test... #/spec/controllers/api/v1/users_controller_spec.rb require 'rails_helper' describe Api::V1::UsersController, :type => :controller do before(:each) { request.headers['Accept'] = "application/vnd.marketplace.v1" } describe "GET #show" do before(:each) do @user = FactoryGirl.create :user get :show, params: {id: @user.id}, format: :json end it "returns the information about a reporter on a hash" do user_response = JSON.parse(response.body, symbolize_names: true) expect(user_response[:email]).to eql @user.email end it { should respond_with 200 } end end And here's a completely unexpected RSpec error Devise::MissingWarden: Devise could not find the `Warden::Proxy` instance on your request environment. Make sure that your application is loading Devise and Warden as expected and that the `Warden::Manager` middleware is present in your middleware stack. If you are seeing this on one of your tests, ensure that your tests are either executing the Rails middleware stack or that your tests are using the `Devise::Test::ControllerHelpers` module to inject the `request.env['warden']` object for you. So I go here - http://www.rubydoc.info/gems/devise/Devise/Test/ControllerHelpers and tried this -> include Devise::Test::ControllerHelpers which didn't help because the file controller_helpers.rb is nowhere in my project What did I miss here? Thanks

Rails Devise token and cookie session at same time Posted: 17 Jul 2016 06:37 AM PDT I have a rails web which has been using cookie session authentication (devise) from its beginning. Now, we are developing an ionic mobile application which uses the API available from the rails application. I have considered to use JWT or token authentication for this new application but I can't find a way to combine both authentication methods, cookie and JWT. Also, both applications have different requirements. For example, in the web a user can have concurrent sessions only if he/she has a certain role. On the opposite, in the mobile application it is possible to have concurrent session without any restriction. I have reading a lot trying to figure how to combine both methods but I can't find the way. Maybe I should consider to use only one of the methods (JWT) or use another approach (doorkeeper).

Rails simple_form with multi belongs_to association Posted: 17 Jul 2016 05:36 AM PDT In my app I have lots of model: (products belongs_to creator, creators belongs_to compagnie, compagnies belongs_to SEO, SEOs belongs_to user) in my first Seoscontroller I have that: def create @seo = current_user.seos.build(seo_params) if @seo.save redirect_to search_path else render :new end end (Controller work find!)

Execute JS every time on the event of turbolinks load in Rails 5 app Posted: 17 Jul 2016 05:15 AM PDT I would like to execute a few lines of js every time turbolinks is loaded(i.e, the page is loaded), not the js from cache, but would like to force run it before the event of turbolinks load, every time. Is that possible? I'm trying to get rid of FOUC here, by hiding the html body and doing this in app.js.coffee $(document).on 'turbolinks:load', -> document.body.style.visibility = 'visible' But the FOUC starts kicking in after the 3rd or 4th time of reloading the page. To see this live in action, here is a link to the website.

Ruby on Rails: Optimising multiple http requests to another server Posted: 17 Jul 2016 06:36 AM PDT My app makes http requests to another server on behalf of users. This question concerns doing this in the optimal way. The app may need to return the result of many http requests (to foreign server) to a user as quickly as possible. I have used threading to optimise this as best I can. However, I don't know enough to understand what happens when multiple users use the site at once. Bizarrely, when I simulated a few users making requests to the (local) development server at the same time, the response time didn't appear to suffer at all. I was thinking of making a class that queues http requests and processes them when it can, however, I wouldn't know whether to instantiate it at App level or User level. The local Web server is webrick and the production server is puma. Questions: What happens when multiple users make requests to my site (where, for each request, my site must in turn make multiple requests to another site)? How do I optimise response times? Is having the users of my site send requests to the foreign site directly (ajax) a possibility?

Rails app, dashboard routes Posted: 17 Jul 2016 02:13 AM PDT I am trying to create a dashboard for my app. It is not a normal admin panel as I am trying to localize each dashboard to separate models. In other words, I have a model Shop. Each shop has_many Products. Each shop has its own Dashboard which allows a user who has a position at this shop to create and edit this shops products. I am struggling when it comes to designing the routes so that when an employee goes to site.com/shops/5/dashboard he enters his/hers shop dashboard and sees all action he/she is allowed to manage(add product, edit product, add employee, edit employee, etc.). Currently, the routes look like this: resources :shops do resources :products resources :positions resource :dashboard, only: [:show] end How to separate the :new, :edit, :destroy actions in a namespace so that later I can access all dashboard actions? Would the following be unreasonable for my situation? resources :shops do resources :products, only: [:show, :index] resource :dashboard, only: [:show] namespace :dashboard do resources :products, only: [:new, :edit, :update, :destroy] resources :positions end end

Ruby Rails - Where to start my understanding Posted: 17 Jul 2016 02:56 AM PDT I'm trying to learn code and currently running through the exercises within codecademy for Rails. Though I find this a good learning resource, i'm struggling to understand the relevance of the commands etc to "real life", so I can relate to it. Can anyone recommend "real life" projects to work through on line re. rails, so I can piece all the fundamental pieces together, whilst seeing what my actions do to the outcome project. Thank you in advance. Brendan

Correctly filled fields should stay filled after error (Angular) Posted: 17 Jul 2016 01:26 AM PDT I have a problem with register fields in my app. This is my views new.html.slim - if organization .grid__cell.unit-12-24.unit-10-24--xs = f.text_field :email_organization, name: "email_organization", value: resource.email_organization, placeholder: current_organization.placeholder_selected ? current_organization.placeholder : 'Email...', 'ng-model' => 'emailOrganization', class: "ui-input #{resource.email_organization? ? 'ui-input--error' : ''}" When I fill others field wrong - correct field email_organization are empty, and when I delete line 'ng-model' => 'emailOrganization' - everything is ok - correct email field stays after error (incorrect fields are empty) - but I don't want to delete this line because I want to use validation for this field. My validation directive validate_email_organization.coffee angular.module("validators").directive 'validateOrganization', -> restrict: 'A' require: 'ngModel' link: (scope, element, attrs, ctrl) -> name = attrs['name'] || 'emailOrganization' scope.$watch attrs.ngModel, (value) -> unless value ctrl.$setValidity(name, true) return REGEXP = /^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))$/ ctrl.$setValidity(name, REGEXP.test(value)) What I did wrong?

How to develop new features for rails app without affecting existing website Posted: 17 Jul 2016 01:25 AM PDT I have recently launched version 1 of my web application and it is currently online and im getting a small amount of traffic on a daily basis. I now need to start developing new features for my application and also have the ability to test these features online on heroku without affecting the existing website until the feature is fully developed and ready to go live. How can I do this? Is it as simple as creating a new branch with git? Or is there a way to have a seperate url that only I can access in which I can push these new features and test them out before pushing it to my main site?

Rails database migration fails with “duplicate column name: email” Posted: 17 Jul 2016 05:30 AM PDT I am fairly new to Rails and I'm currently installing the devise gem. When I created a User model and attempted to migrate the database: $ rails generate devise User $ rake db:migrate I get the following error response: == 20160717064710 AddDeviseToUsers: migrating ================================= -- change_table(:users) rails aborted! StandardError: An error has occurred, all later migrations canceled: Mysql2::Error: Duplicate column name 'email': ALTER TABLE `users` ADD `email` varchar(255) DEFAULT '' NOT NULL Tasks: TOP => db:migrate (See full trace by running task with --trace) I'm not exactly sure what a schema is for, but here is a copy of my schema. It's empty, and I thought it was suppose to be until the database is migrated: ActiveRecord::Schema.define(version: 0) do end And here is a copy of my migration file in db/migrate: class DeviseCreateUsers < ActiveRecord::Migration[5.0] def change create_table :users do |t| ## Database authenticatable t.string :email, null: false, default: "" t.string :encrypted_password, null: false, default: "" ## Recoverable t.string :reset_password_token t.datetime :reset_password_sent_at ## Rememberable t.datetime :remember_created_at ## Trackable t.integer :sign_in_count, default: 0, null: false t.datetime :current_sign_in_at t.datetime :last_sign_in_at t.string :current_sign_in_ip t.string :last_sign_in_ip ## Confirmable # t.string :confirmation_token # t.datetime :confirmed_at # t.datetime :confirmation_sent_at # t.string :unconfirmed_email # Only if using reconfirmable ## Lockable # t.integer :failed_attempts, default: 0, null: false # Only if lock strategy is :failed_attempts # t.string :unlock_token # Only if unlock strategy is :email or :both # t.datetime :locked_at t.timestamps null: false end add_index :users, :email, unique: true add_index :users, :reset_password_token, unique: true # add_index :users, :confirmation_token, unique: true # add_index :users, :unlock_token, unique: true end end I'm fairly new to Rails, so I'm actually quite lost on what this error means. I'm assuming I apparently already have a column named: "email". Also, I commented out the t.string :email and typed the following: rails db:rollback rails db:migrate And I get a differnet error: Mysql2::Error: Key column 'email' doesn't exist in table: CREATE UNIQUE INDEX `index_users_on_email` ON `users` (`email`)

Using Appscript with Rails Posted: 17 Jul 2016 06:22 AM PDT I've installed the rb-scpt gem in my Rails project and ran bundle. The gem is a fork from rb-appscript. The following program works when run from Terminal: #!/usr/bin/env ruby # List names of playlists in iTunes. require "rb-scpt" itu = Appscript.app("iTunes") p itu.sources[1].user_playlists.name.get I created a controller to do the same thing: class ItunesController < ApplicationController def play itu = Appscript.app('iTunes') play_list = itu.sources[1].user_playlists.name.get render text(play_list) end end When I run it, I get an error on line 3: <NameError: uninitialized constant ItunesController::Appscript> What am I missing? I'm sure it's something simple.

Command to start rails server when using Puma + Nginx Posted: 16 Jul 2016 10:07 PM PDT I just pushed my Rails app to my remote server using Capistrano. The app is deployed under the deploy user's home directory - /home/deploy/my_app/current/ I'm using puma as a web server and have nginx configured to look for a socket to which it should forward all incoming web traffic. Snippet from my nginx site config file - upstream app { server unix:/home/deploy/my_app/shared/sockets/puma.sock fail_timeout=0; } Correspondingly, my puma.rb file uses bind to create the same socket mentioned above. # config/puma # Change to match your CPU core count workers Integer(ENV["PUMA_WORKERS"] || 2) # Min and Max threads per worker threads 1, Integer(ENV["PUMA_MAX_THREADS"] || 5) DEPLOY_ROOT = "/home/deploy/my_app" app_dir = File.expand_path("../..", __FILE__) shared_dir = "#{DEPLOY_ROOT}/shared" # Default to production port ENV["PORT"] || 3000 rails_env = ENV['RAILS_ENV'] || "production" environment rails_env # Set up socket location bind "unix://#{shared_dir}/sockets/puma.sock" # Logging stdout_redirect "#{shared_dir}/log/puma.stdout.log", "#{shared_dir}/log/puma.stderr.log", true # Set master PID and state locations pidfile "#{shared_dir}/pids/puma.pid" state_path "#{shared_dir}/pids/puma.state" activate_control_app on_worker_boot do require "active_record" ActiveRecord::Base.connection.disconnect! rescue ActiveRecord::ConnectionNotEstablished ActiveRecord::Base.establish_connection(YAML.load_file("#{app_dir}/config/database.yml")[rails_env]) end The last piece is to start my Rails app. What is the command that I should use to start it? I tried SECRET_KEY_BASE=blahblahblah rails s -e production --daemon however this did not create a socket at the path mentioned above. I also confirmed it by trying to hit my URL and nginx threw up a 502 bad gateway. Should I be using puma -C config/puma.rb instead? What's the difference, I assume rails server starts puma anyway. And how do I get that socket to be created? Thanks! EDIT: When I search for the puma process that's running, it tells me it's listening on a TCP port. I'm not sure how that differs from sockets, but could that be the problem? [01:08:09] deploy:~ > ps aux | grep puma deploy 12132 0.0 7.6 523736 78160 ? Sl 00:59 0:00 puma 3.4.0 (tcp://localhost:3000) [/] deploy 12314 0.0 0.0 14512 936 pts/0 S+ 01:08 0:00 grep puma

How to call Rails ActiveModel.some_class_method from external thread without of connections broking? Posted: 16 Jul 2016 10:28 PM PDT I have a Rails (4.2.6) app and my extending class 'lib/messaging.rb': # lib/messaging.rb class Messaging include Singleton # this method could be called from continous thread from antoher class from 'lib' def event_starts_today Thread.new{ Friend.invite } end def invitation_accepted(friends) Thread.new do # using this to obtain and close connection within the new thread friends.each do |friend| ActiveRecord::Base.connection_pool.with_connection do Friend.find(friend.id).thanks} end end end end which communicates with the class Friend: # app/models/friend.rb class Friend < ActiveRecord::Base def self.invite free_friends = [] # trying to protect this for calls from external threads ActiveRecord::Base.connection_pool.with_connection do free_friend = Friend.where(is_busy: false).to_a end Messaging.instance.invitation_accepted free_friends end def say_thanks ... end end I suggest that I am doing not in the best way, but Your help would help to understand the way)) The problem outstands in exceptions's messages: No connection pool ActiveRecord::ConnectionNotEstablished I followed pt.3 from recommendations here http://api.rubyonrails.org/classes/ActiveRecord/ConnectionAdapters/ConnectionPool.html#method-i-checkout and other publications that leaded me to understanding that if I use a query on an ActiveModel within a separate Thread then I have to close the connection within this thread. These lead me to using ActiveRecord::Base.connection_pool.with_connection(&block) method. And there is still something wrong( I suggest that I need to join Messaging and Friends somehow in Rails way, but I am confused if the only way is to make http requests(and then all the process will be under Rails controlled threads). I can't catch how to move this Messaging under Rails control. I have also #conf/initializers/messaging.rb Messaging.instance.init # this was cut from post but exists and # config/application.rb module App class Application < Rails::Application ... config.autoload_paths += %W(#{config.root}/lib) end end The code is abstracted but represents a real issue. In the real could occur thread-in-thread and sequential queries, but I use the #with_connection(&block) and completing queries with #to_a or #find within each of the &block. But something is wrong((.. Thanks more for any help!! I am really in stuck with this(

Value not being persisted on form error Posted: 16 Jul 2016 09:27 PM PDT I have a form, that won't persist (or at least fill) the date input when the submission fails. For example, let's say I have a form that has two inputs, :date and :post. Both inputs are required. If I fill in :post, the form errors saying :date is require, but it persist and fills the :post value when it errors. Which is normal behavior. If I fill :date and leave :post blank, it errors again. However, this time it won't persist (or at least fill) the :date field when it re-renders the form. Clearly the :date is being passed through, so not a strong param issue. And I can manually fill in the :date field on error. Setting value for the :date input to params[:form][:date] works, but I shouldn't have to do that. The value is clearly in the params hash, it just isn't being fill when the form errors. Every other value on the form is being set, just not that :date value. It's not a huge issue, but it is driving me nuts. And as of right now, I'm out of ideas. Any help would be appreciated.

Coffee script event not firing - why not? Posted: 16 Jul 2016 09:53 PM PDT I cannot seem to get a coffee script even firing. My code is below - and i hope it will help someone in future. Question: Why isn't the coffee script firing? what am i trying to do I'm trying to create a dynamic selection menu, like in Ryan Bates' railcasts: http://railscasts.com/episodes/88-dynamic-select-menus-revised?view=comments I'm trying to create three selection menus. First the user selects the client, then the project, then the building. A client has many projects which has many buildings. Obviously we want to limit user choices otherwise they'd have to choose from over 100 buildings if these results weren't filtered by first selecting the client and then project. Here is my coffeescript: ## This bit works fine jQuery -> projects = $('#project_id').html() #Gets the project drop down elements $('#client_id').change -> #If we change our client selection then: client = $('#client_id :selected').text() # OBtain the client options = $(projects).filter("optgroup[label='#{client}']").html() #Filter all projects by client if options $('#project_id').html(options) # redraw the drop down menu to show only projects by a specific client. else $('#project_id').empty() #This is not firing for some reason ----------------> $('#project_id').change -> alert('hello') buildings = $('#building_id').html() project = $('#project_id :selected').text() options1 = $(buildings).filter("optgroup[label='#{project}']").html() if options1 $('#building_id').html(options1) else $('#building_id').empty() And here is my form: <%= form_for(@rate) do |f| %> <%= render "shared/errors", object: @rate %> <fieldset> <ol> <li class="required"> <%= 'client_id included' %> <%= collection_select(:client, :client_id, Client.all, :id, :name, {include_blank: true}, html_options = {:id => 'client_id'} ) %> </li> <li class="required"> <%= "Now for the project" %> <%= grouped_collection_select :building, :project_id, Client.all, :projects, :name, :id, :name, {include_blank: true}, html_options = {:id => 'project_id'} %> </li> <li class="required"> <%= "Now for the building" %> <%= grouped_collection_select :rate, :building_id, Project.order(:name), :buildings, :name, :id, :name, {include_blank: true}, html_options = {:id => 'building_id'} %> </li> <!-- The bits in the middle are more or less superfluous '--> </ol> <p> <%= f.submit %> <%= link_to "Cancel", rates_path, class: 'button' %> </p> </fieldset> <% end %> Any idea where the problem is? Any assistance much appreicated.
