| Ruby on Rails query: find all entity that contains fixed strings Posted: 22 Jun 2016 08:07 AM PDT I have the following Ruby on Rails entity: Playlist: class Playlist < ActiveRecord::Base { :id => :integer, :name => :string, :created_at => :datetime, :updated_at => :datetime, :dimension => :string, :title => :string, :text => :string, :price => :float, :playlist_image_file_name => :string, :playlist_image_content_type => :string, :playlist_image_file_size => :integer, :playlist_image_updated_at => :datetime, :main => :boolean, :action => :string, :hairdresser_id => :integer }
And Keyword: class Keyword < ActiveRecord::Base { :id => :integer, :name => :string, :created_at => :datetime, :updated_at => :datetime, :preselected => :boolean }
The relation between them is very simple: basically a Playlist object can have 0 or more keywords associated. Those are the models: class Keyword < ActiveRecord::Base has_and_belongs_to_many :playlists end class Playlist < ActiveRecord::Base has_and_belongs_to_many :keywords has_attached_file :playlist_image, styles: {medium: "500x500", small: "200x200", thumb: "40x40"}, default_url: "/system/playlist_default.jpg" validates_attachment_content_type :playlist_image, content_type: /\Aimage\/.*\Z/ end
That allows me to do something like that: Playlist.first.keywords
and retrieve all the keywords associated with the first playlist. Now I would like to build a function to return all the playlists that have certain words as keywords and have "main" equals to true. For example all the playlist that have the keyword "Summer". I tryed with that: Playlist.where(:main => true).map{|x| x.keywords.include? "Summer"}
But that returns only an array containing true or false depending if the related Playlist contains or not the keyword "Summer", I'm looking for something that return the whole playlist only if the array of keywords of that playlist include the word "summer". How can I achieve that? |
| Using both has_one and has_many association Posted: 22 Jun 2016 08:03 AM PDT I'm trying to the has_one and has_many methods in one model. A taskflow can have many tasks but it also has a single default task. I'm trying to create a column in the taskflow table that contains the id of a task. However when I try and set that default task it does not work. class Taskflow < ActiveRecord::Base has_many :tasks has_one :default_task, :class_name => 'Task' class Task < ActiveRecord::Base belongs_to :taskflow
I seed the database then in the rails console I try to assign a task to be a taskflow default_task: taskflow1 = Taskflow.first task1 = Task.first taskflow1.default_task = task
This doesn't work with the taskflow default_task value remaining 'nil'. What the correct way to achieve the desired behaviour? Any help would be much appreciated. |
| Shorthand block syntax for factory_girl traits Posted: 22 Jun 2016 08:00 AM PDT Is it possible to use the shorthand block syntax for factory_girl traits? Consider this factory: FactoryGirl.define do factory :foo do name "name" # not using the block shorthand {} syntax, instead using do...end block syntax trait :my_name do name "Neil" end end end
And using this factory works: create(:foo, traits: [:my_name])
However I would like to use the shorthand block syntax for my traits like so: FactoryGirl.define do factory :foo do name "name" # using shorthand block syntax but does not work trait :my_name {name "Neil"} end end
And now using this factory errors out. Here is what happens: create(:foo, traits: [:my_name])
syntax error, unexpected '{', expecting keyword_end (SyntaxError) This seems odd because I thought that wherever you use do ... end you can opt for the shorthand {} block syntax. Question: Is there something wrong with my shorthand block syntax for the factory_girl trait method and that is why it is erroring out? Or: are you just not allowed to use the shorthand block syntax with factory_girl traits? Is there a way to make using the shorthand block syntax for factory_girl traits work?

| Access count of message received? Posted: 22 Jun 2016 07:48 AM PDT Is it possible to access in a test how many times an object has received a certain message? My goal is to test that a class has received two class method calls the same number of times. Logically, it seems like this count would be stored somewhere as code is executed. This would look something like allow(SomeClass).to receive(:method_1).at_least(1).times allow(SomeClass).to receive(:method_2).at_least(1).times # setup and code here expect(method_1_received_times).to eq (method_2_received_times)

| Html radio button labels don't select the proper radio button (Ruby on Rails) Posted: 22 Jun 2016 06:03 AM PDT (Ruby on Rails application) I'm having a problem with selecting radio buttons by clicking their designated labels (I have multiple forms on the same page). In my application, I have a Conversations resource, where in its show page Users can send Messages into the conversation. In 'conversations/show' users can React to each others' messages. I use a ReactionExample model to create a few reaction_examples at a time, which users can select and create their own new instance of Reaction from. here is the show action in conversations controller def show @conversation = Conversation.find(params[:id]) @messages = @conversation.messages.all @reaction_examples = ReactionExample.all #These are "like", "hate", etc... end
here is my 'conversations/show' view <% @messages.each do |message| %> <p><%= message.user.first_name %> says <%= message.content %></p> <%= form_for message.replies.build, url: reaction_conversation_path(@conversation) do |f| %> <%= f.hidden_field :message_id, value: message.id %> <%= f.hidden_field :user_id, value: current_user.id %> <% @reaction_examples.each do |example| %> <%= f.radio_button :reaction_example_id, example.id %> <%= f.label :reaction_example_id, example.phrase, value: example.id %> <% end %> <%= f.submit "Send reaction" %> <% end %> <% end %>
Here is my problem: in this view ('conversations/show') there will be multiple forms to send a reaction. Each of these forms will have more than one radio button and label with the same value, just a different :message_id on each form. I would like to be able to select a reaction radio button by clicking its label, but there are multiple forms on this page with radio buttons WHICH HAVE THE SAME LABEL VALUE. So when I click a radio button label on the third or fourth message down on the page, it selects the radio button on the first message up on the page. It's because they technically have the same value since the same ReactionExample id's are being used in each radio button in the forms. Any help is appreciated. Thank you in advance! |
| Rails associations for organisation with multiple locations Posted: 22 Jun 2016 08:04 AM PDT I have the following models: Organisation, Valuation and Capability. The Organisation model used to have a country field, but it came to my attention it can have multiple locations. To solve this I could create a Location model and add a has_many relation between Organisation and Location, equally however a location can belong to more than one organisation. For example, Organisation X might have a location in UK, DE and US and organisation Y might have a location in UK and DE. The bigger problem lies with Valuation which describes valuations of a organisation at a specific location for a specific capability. So where the valuation at organisation X in location Y might be 10, it could be 8 for organisation X at location Z. Right now Valuation has belongs_to assocations to both Organisation and Capability: class Valuation < ApplicationRecord belongs_to :organisation belongs_to :capability end
To account for the location, I would need to add another association, but I am looking for some hints as to which one. The question then is, how to set up my assocations so I can ask questions like: "what is the average valuation of organisation x with capability y over all locations" or "what is the valuation of organsiation x for capability y at location z" EDIT Ended up going with the many-to-many approach, ended up with the models: class Organisation < ApplicationRecord has_many :memberships has_many :locations, through: :memberships end class Location < ApplicationRecord has_many :memberships has_many :organisations, through: :memberships end class Membership < ApplicationRecord belongs_to :organisation belongs_to :location end
Question now is to link this to Valuation |

2 - It redirects a user to a method result where is another method scan_links to find all links on the given website and save it to an array @links: def result link = Link.find(session[:link_id]) @data = scan_links(link.url) end def scan_links(url) @links = [] Spidr.site(url) do |spider| spider.every_url do |url| @links << url.to_s end end end
3 - I wrote another method to access the object @links and count it in a real time + respond in json object every second with ajax request. def real_time_count_links respond_to do |format| format.html format.json {render json: @links.count} end end
4 - And finally I wrote the ajax request for that method to access it every second: function openScan() { document.getElementById("Scan").style.height = "100%"; function doAjax() { $.ajax({ type: 'get', url: "/links/real_time_count_links", dataType: 'json', success: function(response) { alert("ok.") }, complete: function (data) { // Schedule the next setTimeout(doAjax, 1000); } }); }; setTimeout(doAjax, 1000); }
There is something wrong with it, not sure what and I don't think so this is the best way to handle it. How I can access data in ajax in real time till the page / method "result" is fully loaded and shows all the links? |

| How to login into active admin with two user models Posted: 22 Jun 2016 04:04 AM PDT I have 2 different types of users in my rails application. For those 2 types of users, i created two different models. I want to give login access for both models (Webadmin, Owner). My routes.rb file : devise_for :webadmins, ActiveAdmin::Devise.config.merge({path: '/webadmin'}) devise_for :owners, ActiveAdmin::Devise.config ActiveAdmin.routes(self)
My activeadmin.rb file : config.load_paths = [File.join(Rails.root,'app','webadmin'), File.join(Rails.root,'app','owner')] config.default_namespace = :webadmin config.namespace :webadmin do |webadmin| webadmin.authentication_method = :authenticate_webadmin! webadmin.current_user_method = :current_webadmin webadmin.logout_link_path = :destroy_webadmin_session_path end config.namespace :owner do |owner| owner.authentication_method = :authenticate_owner! owner.current_user_method = :current_owner owner.logout_link_path = :destroy_owner_session_path end
when i am running my application using rails s, i am getting the following error. /home/brilliance/.rvm/gems/ruby-2.2.1/gems/devise-3.5.6/lib/devise/rails/routes.rb:499:in `raise_no_devise_method_error!': Webadmin does not respond to 'devise' method. This usually means you haven't loaded your ORM file or it's being loaded too late. To fix it, be sure to require 'devise/orm/YOUR_ORM' inside 'config/initializers/devise.rb' or before your application definition in 'config/application.rb' (RuntimeError)
I tried a lot of answers from google and stackoverflow. But No luck. Please help me out. |

| Openstack Ovh connection configuration Posted: 22 Jun 2016 03:46 AM PDT I am currently working on a rails app and I want to use Openstack with object storage from OVH. My error is : connect_nonblock': SSL_connect returned=1 errno=0 state=unknown state: certificate verify failed (OpenSSL::SSL::SSLError) Unable to verify certificate. This may be an issue with the remote host or with Excon.Excon has certificates bundled, but these can be customized.Excon.defaults[:ssl_ca_path] = path_to_certs,ENV['SSL_CERT_DIR'] = path_to_certs,Excon.defaults[:ssl_ca_file] = path_to_file,ENV['SSL_CERT_FILE'] = path_to_file,Excon.defaults[:ssl_verify_callback] = callback(see OpenSSL::SSL::SSLContext#verify_callback), orExcon.defaults[:ssl_verify_peer] = false` (less secure). (Excon::Errors::CertificateError) Does anyone have a tips to do it ? I have followed this tutorial in french: https://gist.github.com/BaptisteDixneuf/85dc4419a0398446d2d3 and there is my carrierwave config file : CarrierWave.configure do |config| config.fog_provider = 'fog/openstack' config.fog_credentials = { :provider => 'OpenStack', :openstack_username => ENV['OS_USERNAME'], :openstack_api_key => ENV['OS_USER_MDP'], :openstack_auth_url => ENV['OS_AUTH_URL'], :openstack_region => 'GRA1' } end
