| Many to many with polymorphic association doesn't work in both directions Posted: 15 May 2016 06:53 AM PDT I am implementig the system that enable user to follow the "followable"( in my case these may be an event, place or other user). My idea: Follow model holds the user_id, followable type and followale_id(join table) class Follow < ActiveRecord::Base belongs_to :user belongs_to :followable, polymorphic: true end
Event class Event < ActiveRecord::Base has_many :follows, as: :followable has_many :users, through: :follows end
Place class Place < ActiveRecord::Base has_many :follows, as: :followable has_many :users, through: :follows end
User class User < ActiveRecord::Base has_many :follows has_many :events, through: :follows, source: :followable, source_type: "Event" has_many :locals, through: :follows, source: :followable, source_type: "Local" has_many :users, through: :follows, source: :followable, source_type: "User" end
The problem is that the realtion works only in one direction, i can do: user.follows.create(followable:event1) #follow event1 user.follows.create(followable:place1) #follow place1 user.follows.create(followable:user1) #follow user1 user.follows # displays all following relations user has established
But, i cannot do: event1.follows #return follow objects(some user - event1 pairs) event1.users #return all of the users that follow this event user1.users #return all of the users that user1 follows, the most confusing part..
All of the aboves return nil. How should i establish the relations to make it work in both directions?
Also, i'd like to hear some remarks on how to improve this idea, beacouse it's the first time i'm playin around with more complex realtions. Thank you in advance. |
| Every RSpec test run requires rake db:test:prepare or equivalent using Rails 4.2.5 Posted: 15 May 2016 06:38 AM PDT Using Ruby 2.0.0, Rails 4.2.5, RSpec 3.4.4, Shoulda-matcher 3.1.1, Database_cleaner 1.4.0, PostgreSQL 9.4.5. For every rspec (or rake spec) I have to prepare the test database. If I don't, I receive the "Migrations are pending." message. Everything I read tells me this is not right given Rails 4.1+. I've taken every corrective action that I can find to no avail. Preparing the test database means I either use "rake db:test:prepare", which is deprecated, or a series of "rake db:drop/create/migrate RAILS_ENV=test". Either works. A simple migrate after a test does not work as it tries to recreate all the tables though they exist. None of these problems exist in development or on Heroku production as all migrations are processed and work fine. Rails_helper.rb contains the command "ActiveRecord::Migration.maintain_test_schema!" which should control this problem. In actual fact, that command is the one that identifies that a migration is required and throws the "Migrations are pending." message. I tried including the command "ActiveRecord::Migrator.migrate(File.join(Rails.root, 'db/migrate'))" to check and force a migration if required, but that is the same as running a new migrate and causes the problem I mentioned about recreating existing tables. I did use "rails generate rspec:install" to rebuild .rspec, spec_helper.rb and rails_helper.rb and then update the new files to try to solve the problem. I also migrated all of my configurations over to rails_helper.rb. spec_helper.rb is all comments. The failure is as follows: rake spec Running rails_helper.rb D:/BitNami/rubystack-2.0.0-38/ruby/lib/ruby/gems/2.0.0/gems/activerecord-4.2.5/lib/active_record/migration.rb:392:in `check_pending!': (ActiveRecord::PendingMigrationError) Migrations are pending.

| pass number_field value to rails controller with ajax Posted: 15 May 2016 06:42 AM PDT I want to pass value from number_field_tag to my rails controller on click of this event :onclick => "getVal()" my javascript and ajax is like this function getVal(){ var quant = document.getElementById("quantity").value; console.log(quant); $.ajax({ type: 'POST', url: '/carts/add_to_cart', dataType: 'json', data: { quant } }); return false; }
and my route is this on which I want to send data
post '/cart/:product_id' => 'carts#add_to_cart', as: 'add_to_cart'
my route is fine I have checked.. but stuck in ajax.. I think my ajax code has some problem. My browser console is showing this error,
http://localhost:3000/carts/add_to_cart 404 (Not Found)
Please check if there is any problem. |
| Not receiving money in Stripe test transactions (Rails) Posted: 15 May 2016 06:25 AM PDT So I created subscriptions in my Rails app with test API keys from Stripe. The charges I'm creating with dummy cards are going through successfully on my side, but when I'm in Stripe dashboard, the test balance remains the same, as well customer details are not added. I'm not sure what I did wrong.. Do you know why I can't and how can I add those test customer data to Stripe? In the logs, I'm getting 200 OK response, but I'm worried that something isn't going to function in live mode since test balance isn't being updated. class SubscribersController < ApplicationController before_filter :authenticate_user! def new end def update token = params[:stripeToken] customer = Stripe::Customer.create( card: token, plan: 1020, email: current_user.email ) current_user.subscribed = true current_user.stripeid = customer.id current_user.save redirect_to profiles_user_path end end

| Rails asset pipeline - custom js files Posted: 15 May 2016 05:48 AM PDT I have couple of js files in application.js file. Such as; //= require jquery //= require jquery_ujs //= require dropzone //= require jquery.cookie //= require toastr //VENDOR JS BEGINS //= require pace/pace.min //= require modernizr.custom //= require jquery-ui/jquery-ui.min //= require boostrapv3/js/bootstrap.min //= require jquery/jquery-easy //= require jquery-unveil/jquery.unveil.min //= require jquery-bez/jquery.bez.min //= require jquery-ios-list/jquery.ioslist.min //= require jquery-actual/jquery.actual.min //= require jquery-scrollbar/jquery.scrollbar.min //= require bootstrap-select2/select2.min //= require switchery/js/switchery.min //= require imagesloaded/imagesloaded.pkgd.min //= require jquery-isotope/isotope.pkgd.min //= require classie/classie //= require codrops-stepsform/js/stepsForm //= require bootstrap-datepicker/js/bootstrap-datepicker //= require bootstrap-datepicker/js/locales/bootstrap-datepicker.tr.js //= require bootstrap-datepicker/js/locales/bootstrap-datepicker.en.js //= require summernote/js/summernote.min //= require moment/moment-with-locales.min //= require bootstrap-daterangepicker/daterangepicker //= require bootstrap-timepicker/bootstrap-timepicker.min //= require codrops-dialogFx/dialogFx //= require ion-slider/ion.rangeSlider.min //= require owl-carousel/owl.carousel.min
I have also couple of js codes in the html.erb pages. But I want to take all page specific js codes into 1 file. This file should be called after page loads. Because some of them uses ruby code such as init lat lng of google maps. Also, couple of js files such as; //= require codrops-dialogFx/dialogFx //= require ion-slider/ion.rangeSlider.min
works after page loads. So, they do not work as I put them to head tag as; <%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
So If I, design application.js as; //= require jquery //= require jquery_ujs //= require dropzone //= require jquery.cookie //= require toastr
Then call <%= javascript_include_tag 'application', 'data-turbolinks-track' => true %> in head tag then call all the other js files in the body tag like <%= javascript_include_tag 'pace/pace.min', 'data-turbolinks-track' => true %> <%= javascript_include_tag 'modernizr.custom', 'data-turbolinks-track' => true %> <%= javascript_include_tag 'jquery-ui/jquery-ui.min', 'data-turbolinks-track' => true %> <%= javascript_include_tag 'boostrapv3/js/bootstrap.min', 'data-turbolinks-track' => true %> ....
Does rails precompiles these files also?. I have these js files in vendor file. |

| Map one controller action on another action rails Posted: 15 May 2016 05:00 AM PDT I have a controller named carts_controller and in my routes I am using restful routes i.e., resources :carts. I know resources create default actions like create, index etc., but if I don't want to user create and create a method add_to_cart and in routes I have defined its route as post '/add_cart/:product_id/' => 'carts#add_to_cart', as: 'add_to_cart'
Does this route considered RESTFUL? I don't want to user all the default RESTFUL routes created by resources. I want some custom actions in place of these. My code is working but I am confused as my concepts are not clear. Another thing is if I know that I need product_id in my routes, should I make them nested inside products resources or it will work if I define custom ad I defined above? Any help would be appreciated! |

| Paperclip error after test completed Posted: 15 May 2016 03:46 AM PDT I have a problem with testing paperclip with dropzone. Basically the test works 100% ok, but after the test being executed it calls routing error, because the app didn't find the image, that was currently processed in test. I tested the correctness of image link created, it's there.
Basically I have this test: let!(:announcement3) do create(:announcement, announcement_images: [create(:announcement_image), create(:announcement_image)]) end it 'can set second image as primary' do login_as user, scope: :user visit edit_area_announcement_path(announcement3.slug) click_link I18n.t('simple_form.buttons.announcements.next') all('[data-primary="not_set"]')[1].click click_link I18n.t('simple_form.buttons.announcements.finish') expect(Announcement.last.main_image_index).to eq(Announcement.last.announcement_images.last.id) end
And after this test completes, I receive this error: Failure/Error: Unable to find matching line from backtrace ActionController::RoutingError: No route matches [GET] "/home/vyivrain/Documents/Job/pets/public/system/announcement_images/images/000/000/001/original/synchronised-5th-generation-alliance-magni.jpg" # /home/vyivrain/.rvm/gems/ruby-2.3.0/gems/actionpack-4.2.6/lib/action_dispatch/middleware/debug_exceptions.rb:21:in `call' # /home/vyivrain/.rvm/gems/ruby-2.3.0/gems/actionpack-4.2.6/lib/action_dispatch/middleware/show_exceptions.rb:30:in `call' # /home/vyivrain/.rvm/gems/ruby-2.3.0/gems/railties-4.2.6/lib/rails/rack/logger.rb:38:in `call_app' # /home/vyivrain/.rvm/gems/ruby-2.3.0/gems/railties-4.2.6/lib/rails/rack/logger.rb:20:in `block in call' # /home/vyivrain/.rvm/gems/ruby-2.3.0/gems/activesupport-4.2.6/lib/active_support/tagged_logging.rb:68:in `block in tagged' # /home/vyivrain/.rvm/gems/ruby-2.3.0/gems/activesupport-4.2.6/lib/active_support/tagged_logging.rb:26:in `tagged' # /home/vyivrain/.rvm/gems/ruby-2.3.0/gems/activesupport-4.2.6/lib/active_support/tagged_logging.rb:68:in `tagged' # /home/vyivrain/.rvm/gems/ruby-2.3.0/gems/railties-4.2.6/lib/rails/rack/logger.rb:20:in `call' # /home/vyivrain/.rvm/gems/ruby-2.3.0/gems/actionpack-4.2.6/lib/action_dispatch/middleware/request_id.rb:21:in `call' # /home/vyivrain/.rvm/gems/ruby-2.3.0/gems/rack-1.6.4/lib/rack/methodoverride.rb:22:in `call' # /home/vyivrain/.rvm/gems/ruby-2.3.0/gems/rack-1.6.4/lib/rack/runtime.rb:18:in `call' # /home/vyivrain/.rvm/gems/ruby-2.3.0/gems/activesupport-4.2.6/lib/active_support/cache/strategy/local_cache_middleware.rb:28:in `call' # /home/vyivrain/.rvm/gems/ruby-2.3.0/gems/rack-1.6.4/lib/rack/lock.rb:17:in `call' # /home/vyivrain/.rvm/gems/ruby-2.3.0/gems/actionpack-4.2.6/lib/action_dispatch/middleware/static.rb:120:in `call' # /home/vyivrain/.rvm/gems/ruby-2.3.0/gems/rack-1.6.4/lib/rack/sendfile.rb:113:in `call' # ./app/middleware/rack/robots_middleware.rb:12:in `call' # /home/vyivrain/.rvm/gems/ruby-2.3.0/gems/railties-4.2.6/lib/rails/engine.rb:518:in `call' # /home/vyivrain/.rvm/gems/ruby-2.3.0/gems/railties-4.2.6/lib/rails/application.rb:165:in `call' # /home/vyivrain/.rvm/gems/ruby-2.3.0/gems/rack-1.6.4/lib/rack/urlmap.rb:66:in `block in call' # /home/vyivrain/.rvm/gems/ruby-2.3.0/gems/rack-1.6.4/lib/rack/urlmap.rb:50:in `each' # /home/vyivrain/.rvm/gems/ruby-2.3.0/gems/rack-1.6.4/lib/rack/urlmap.rb:50:in `call' # /home/vyivrain/.rvm/gems/ruby-2.3.0/gems/capybara-2.6.2/lib/capybara/server.rb:19:in `call' # /home/vyivrain/.rvm/gems/ruby-2.3.0/gems/rack-1.6.4/lib/rack/handler/webrick.rb:88:in `service'
I just have no idea why it triggers this url and tries to find this image. From stack error, there's only robots_middleware.rb, but that's only refering to robots.txt, it's not possible, that the error is there. Thanks for answering |

| rails use form input value before save Posted: 15 May 2016 12:08 AM PDT I have a form in rails with input values, and 1 of the values is a LOV (List of Values) and a second input field is also a LOV but depends on the input of the other field. The input value of the first field is not saved in between. So I need to use that field value before it is saved. So, the example: I choose a company from the list of values of all companies for the field supplier, the second field supplier_address will be a LOV with all the addresses of that company, so the LOV of the second field is dependent on the value chosen in the first field, company. What I tried: def new @purchase_requisition = PurchaseRequisition.new @purchase_requisition.number = find_next_user_value("Purchase_Requisition") #@purchase_requisition.supplier_address_id = PurchaseRequisition.new.purchase_requisition_params[:supplier_id] @purchase_requisition = PurchaseRequisition.new(purchase_requisition_params) respond_to do |format| @purchase_requisition.supplier_address_id = PurchaseRequisition.new.purchase_requisition_params[:supplier_id] end end
but I still get the error: param is missing or the value is empty: purchase_requisition Can someone please help me? Thank you!!! |

| activerecord-reputation system with has_many through assocations? Posted: 14 May 2016 10:47 PM PDT I would like to setup activerecord-reputation-system gem on my rails app and have the following issue. I have a projects model and a tasks model...however tasks are not necessarily associated with only a single project - they can have many projects. Because of this i created a TaskRelationship model to link tasks to projects. User Model: # for tracking tasks or projects a user created has_many :own_projects, :class_name=>'Project' has_many :own_tasks, :class_name=>'Task'
Task Model: belongs_to :owner, :foreign_key=>'user_id', :class_name=>'User' has_many :taskrelationships, foreign_key: "projecttask_id", class_name: "TaskRelationship", dependent: :destroy has_many :taskprojects, through: :taskrelationships, source: :taskproject

TaskRelationship Model (associates a task with a project): belongs_to :taskproject, class_name: "Project" belongs_to :projecttask, class_name: "Task" validates :taskproject_id, presence: true validates :projecttask_id, presence: true #i would like to add the votes on this task relationship, i.e, #has_reputation :votes, source: :user, aggregated_by: :sum #but I fear the gem may not work this way
I would like the votes to be on the TaskRelationship so that it represents the most voted up tasks with regard to a single project only...From the front-end/UI, the users will be voting from a project profile page that lists out tasks that have been added to that specific project. I was hoping someone could provide some guidance on how to approach this or on whether it can even be accomplished this way...so i won't start off on the wrong foot. thx a lot. |
| Whenever Gem Daily email using actionmailer not sending Posted: 14 May 2016 11:04 PM PDT I can't seem to make the whenever gem work with my actionmailer. I am trying to run the application in development wherein an email would be sent to a specific individual at a specific time. In my schedule.rb file I have the following: every :day, :at => '12:48pm' do runner "FoodPlan.food_email" end
In my controller called food_plans_controller.rb I have: def self.food_email @food_plans = FoodPlan.where(food_plan_date: Date.today).order('meal ASC') UserMailer.food_email(@food_plans).deliver_now end
In user_mailer.rb I have (take note I removed the email for privacy reasons) : def food_email (food) @food_plans = food mail(to: '---------@yahoo.com', subject: 'Food Orders for #{Date.today}') end
I have a folder in the views called user_mailer, inside it is a file called food_email.html.erb with the ff: <!DOCTYPE html> <html> </head> <body> <h1>title</h1> <p> Good morning, -----! <br><br> Meal Plans for <%=Date.today%>: <br><br> <table class="table table-bordered table-striped"> <thead> <tr> <th>#</th> <th>Meal Plan</th> <th>Ordered by</th> <th>Room Number</th> <th>Received by</th> <th>Signature</th> </tr> </thead> <tbody> <%countint=1%> <% @food_plans.each do |food_plan| %> <tr> <td><%=countint%></td> <td><%= food_plan.meal %></td> <td><%=food_plan.applicant.first_name%> <%=food_plan.applicant.last_name%></td> <td><%=food_plan.applicant.room_number%></td> <%countint+=1%> <td></td> <td></td> </tr> <% end %> </tbody> </table> <br> <br> ---. <br> <br> If you have any concerns, don't hesitate to call us at ------. <br> <br> Thanks, <br>---- </p> </body> </html>
In my development config I have (I removed the email and password): config.action_mailer.smtp_settings = { address: 'smtp.gmail.com', port: 587, domain: 'example.com', user_name: '-------', password: '-------', authentication: 'plain', enable_starttls_auto: true }
I have tried reading this guide but I cannot still get the gem to work with actionmailer. I have also read up on the documentation of the whenever gem but I still can't figure out what I'm doing wrong. :( I'm not getting any errors, it's just that the email is not sending. |

which results in something like this { "2016-05-13": [ { "id": 4, "provider": "facebook", "likes": -2, "comments": 0, "shares": 0, "views": 0, "reach": 0, "reactions": { "sad_count": "0", "wow_count": "-1", "haha_count": "0", "like_count": "-1", "love_count": "0", "angry_count": "0" } }, { "id": 5, "provider": "facebook", "likes": 2, "comments": 2, "shares": 2, "views": 2, "reach": 0, "reactions": { "sad_count": "0", "wow_count": "0", "haha_count": "0", "like_count": "0", "love_count": "0", "angry_count": "0" } } ], "2016-05-12": [ { "id": 3, "provider": "facebook", "likes": 1, "comments": 3, "shares": 0, "views": 0, "reach": 0, "reactions": { "sad_count": "1", "wow_count": "0", "haha_count": "0", "like_count": "0", "love_count": "0", "angry_count": "0" }, "engagement_id": 1, "participation_id": 1, "campaign_id": 1, "influencer_authorization_id": 1, "influencer_id": 1, "social_account_id": 1, "metrics_date": "2016-05-12", "status": "processed", "deleted_at": null, "created_at": "2016-05-14T11:36:55.995Z", "updated_at": "2016-05-14T11:36:55.995Z" } ], "2016-05-11": [ { "id": 2, "provider": "facebook", "likes": 0, "comments": 16, "shares": 0, "views": 0, "reach": 0, "reactions": { "sad_count": "0", "wow_count": "0", "haha_count": "0", "like_count": "0", "love_count": "0", "angry_count": "0" } } ], "2016-05-10": [ { "id": 1, "provider": "facebook", "likes": 3, "comments": 4, "shares": 0, "views": 0, "reach": 0, "reactions": { "sad_count": "0", "wow_count": "1", "haha_count": "0", "like_count": "1", "love_count": "1", "angry_count": "0" } } ] }
Which is the best way to iterate through to get data like below [ { "date": "24/03/16", "metrics": { "likes_count": "29", "comments_count": "456", "shares_count": "234", "views_count": "65", "clicks_count": "123" } }, { "date": "25/03/16", "metrics": { "likes_count": "345", "comments_count": "234", "shares_count": "876", "views_count": "345", "clicks_count": "45" } }, { "date": "26/03/16", "metrics": { "likes_count": "345", "comments_count": "265", "shares_count": "243", "views_count": "165", "clicks_count": "87" } }, { "date": "27/03/16", "metrics": { "likes_count": "376", "comments_count": "87", "shares_count": "54", "views_count": "754", "clicks_count": "34" } }, { "date": "28/03/16", "metrics": { "likes_count": "103", "comments_count": "324", "shares_count": "405", "views_count": "87", "clicks_count": "354" } }, { "date": "29/03/16", "metrics": { "likes_count": "23", "comments_count": "65", "shares_count": "234", "views_count": "87", "clicks_count": "34" } }, { "date": "30/03/16", "metrics": { "likes_count": "98", "comments_count": "576", "shares_count": "34", "views_count": "365", "clicks_count": "212" } } ]
