| Rails Rspec Capybara Selenium JS create not showing after pressing submit Posted: 16 Oct 2016 07:33 AM PDT I am building a web shop, the functionality is already there, namely: in ONE screen there is a list of products and a list of ordered items. When in a product pressing order, this product then shows up immediately in this list. As you can guess, when wanting to do this with a test, using selenium I see Firefox starting up, I think I even see the button being pressed, but then obviously nothing happens. No item in my order list. Using Rails 5 with an updated capybara and selenium webdriver. gem 'rspec-rails', '~> 3.5', '>= 3.5.1' gem 'capybara', '~> 2.10', '>= 2.10.1' gem "factory_girl_rails", "~> 4.7" gem 'selenium-webdriver', '~> 3.0' gem 'database_cleaner', '~> 1.5', '>= 1.5.3' gem "email_spec", "~> 1.6.0"

| Rails Multi-step form Posted: 16 Oct 2016 07:07 AM PDT I'm writing a quiz app with rails 5. I have got a multi-step form for question building. Models: class Mcq < ApplicationRecord attr_accessor :option_count has_many :options, dependent: :destroy belongs_to :quiz accepts_nested_attributes_for :options validates :question_text, presence: true end class Option < ApplicationRecord belongs_to :mcq, optional: true validates :option_text, presence: true end
Schema: create_table "mcqs", force: :cascade do |t| t.string "question_text" t.boolean "required" t.boolean "multiselect" t.integer "quiz_id" t.datetime "created_at", null: false t.datetime "updated_at", null: false end create_table "options", force: :cascade do |t| t.string "option_text" t.integer "mcq_id" t.datetime "created_at", null: false t.datetime "updated_at", null: false end
The first page is for question setup and has the following fields: - Option Count
- Required (Yes / No)
- No of options that can be selected (Single / Multiple)
The second page is for options and has the following fields: - Question Text
- Nested Form for Options
Controller: class McqsController < ApplicationController def new session[:current_step] ||= 'setup' session[:mcq_params] ||= {} @current_step = session[:current_step] @quiz = Quiz.find(params[:quiz_id]) @mcq = Mcq.new(session[:mcq_params]) if session[:current_step] == 'options' @option_count = session[:mcq_params]['option_count'] @option_count.times { @mcq.options.build } end end def create if params[:previous_button] session[:current_step] = 'setup' redirect_to new_quiz_mcq_path elsif session[:current_step] == 'setup' save_session(params[:mcq]) redirect_to new_quiz_mcq_path elsif session[:current_step] == 'options' @mcq = Mcq.new(whitelisted_mcq_params) @mcq.quiz_id = params[:quiz_id] @quiz = Quiz.find(params[:quiz_id]) if @mcq.save session[:current_step] = session[:mcq_params] = nil redirect_to quiz_new_question_path(@mcq.quiz_id) else @current_step = session[:current_step] render :new end end end private def whitelisted_mcq_params params.require(:mcq) .permit(:question_text, :multiselect, :required, options_attributes: [:option_text]) end def save_session(mcq_params) session[:mcq_params][:option_count] = mcq_params[:option_count].to_i session[:mcq_params][:required] = mcq_params[:required] session[:mcq_params][:multiselect] = mcq_params[:multiselect] session[:current_step] = 'options' end end
The above solution works, but the code is messy and difficult to understand. I came across this railscasts episode which does something similar in a cleaner way. I've updated my code as follows: class Mcq < ApplicationRecord has_many :options, dependent: :destroy belongs_to :quiz attr_writer :current_step attr_accessor :option_count accepts_nested_attributes_for :options validates :question_text, presence: true def current_step @current_step || steps.first end def steps %w[setup options] end def next_step self.current_step = steps[steps.index(current_step)+1] end def previous_step self.current_step = steps[steps.index(current_step)-1] end def last_step? current_step == steps.last end end class McqsController < ApplicationController def new session[:mcq_params] ||= {} @quiz = Quiz.find(params[:quiz_id]) @mcq = Mcq.new(session[:mcq_params]) @mcq.current_step = session[:mcq_step] end def create @quiz = Quiz.find(params[:quiz_id]) session[:mcq_params].deep_merge!(params[:mcq]) if params[:mcq] @mcq = Mcq.new(session[:mcq_params]) @option_count = session[:mcq_params]['option_count'] @option_count.times { @mcq.options.build } @mcq.quiz_id = params[:quiz_id] @mcq.current_step = session[:mcq_step] if params[:previous_button] @mcq.previous_step elsif @mcq.last_step? @mcq.save if @mcq.valid? else @mcq.next_step end session[:mcq_step] = @mcq.current_step if @mcq.new_record? render "new" else session[:mcq_step] = session[:mcq_params] = nil redirect_to edit_quiz_path(@mcq.quiz_id) end end end
But each time the second page is shown, the no of fields for options doubles or in case of invalid entry only the field for question_text is shown. How do I show the options correctly? Should I just go with my first solution? I'm new to rails and don't know much about the best practices. |

I have gone through it step by step but it's still not showing anything? Any advice would be ace. I'm new to rails so bere with me :) Basically I just want to view it on the server :( so any help would be superb. |

My carrer_wave.rb looks like this: if Rails.env.production? CarrierWave.configure do |config| config.fog_credentials = { :provider => 'AWS', :aws_access_key_id => ENV['S3_ACCESS_KEY'], :aws_secret_access_key => ENV['S3_SECRET_KEY'], :region => ENV['S3_REGION'] } config.fog_directory = ENV['S3_BUCKET'] end end
And I'm sure I've configured the AWS access key, secret key, region and bucket properly, which I've confirmed by looking under config vars in the Heroku app. |
| How to debug errors in Rails, Capistrano, Puma deployment Posted: 16 Oct 2016 06:26 AM PDT Ok, I have an app that I deploy with Capistrano.

| Using Heroku w/o depending on add-ons Posted: 16 Oct 2016 05:25 AM PDT I've got a startup that's bootstrapped & they're currently deciding between AWS, DO, & Heroku. There's no dev-ops, so Heroku is a clear winner there, but the pricing of memcached + redis + elasticsearch begins to get heavy. I'd like to use Heroku as an app server and AWS EC2 to house elasticsearch, redis, and memcached...is this a bad idea? Would it make more sense to keep everything under AWS? If we can stick with Heroku for our app server, what's the most inexpensive way to connect our services? (Redis, memcached, elasticsearch) What dangers do we run if we don't have a dev-ops and just do digital ocean (capistrano + rails)? |

| Chaining associated objects won't allow me to call their attributes Rails Posted: 16 Oct 2016 04:21 AM PDT I'm in need of some help. I have been making a blog site in Rails to work on some gems and other techniques and I ran into a problem. I am calling a comment partial into my blog show page as shown here: show.html.slim: - if notice != nil p#notice.alert.alert-success role='alert' = notice h1 Blog Post h4 Title: #{@blog_post.title} h4 Author: #{@blog_post.user.name} h4 Entry: p = @blog_post.blog_entry = render partial: 'comments/form', locals: { comment: @comment } .panel.panel-default .panel-heading h4 Comments #js-comments.panel-body = render partial: 'comments/comment', collection: @blog_post.comments = link_to 'Feed', blog_posts_path, class: 'btn btn-primary'
The issue is in the comments/comment partial: .panel-body p strong = comment.user.username | said at span.posted-at = comment.created_at.strftime('%m/%d/%Y %H:%M:%S') | : p = comment.comment_entry - if policy(comment).update? = link_to 'Edit Comment', edit_blog_post_comment_path(comment.blog_post, comment), class: 'btn btn-primary' - if policy(comment).destroy? = link_to 'Destroy Comment', [comment.blog_post, comment], method: :delete, data: { confirm: 'Are you sure?' }, class: 'btn btn-primary'
Now when I call comment.user.username or comment.created_at.strftime, I got NoMethodError messages saying that username and strftime are undefined methods. However, if I call comment.user and comment.created_at, it works just fine. For some reason it just won't let me add that additional attribute to the chain. I can verify that all the correct associations are in place between the user, blog_post, and comments. Just in case, here is my blog controller for the show page: def show @comment = @blog_post.comments.new end
Any help would be greatly appreciated. Thanks! |

| how to update records in RSpec model spec? Posted: 16 Oct 2016 04:12 AM PDT
I'm trying to find out some good solution for updating records while Rails model testing using RSpec, but I didn't found any exact solution on the internet. So, I'm posting this question with dummy problem and the solution(in answers). I hope that it'll help many other programmers.
So, let's move towards the dummy problem : Let say I've three rails model which are item, inventory & purchase. - item : allow me to create a new Item with the presence of item_name.
- inventory : allow me to view and update available quantity of an item, with the presence of item_id & item_quantity.
The inventory will be automatically created just after the creation of the item with current item's id and with zero quantity. - purchase : allow me to update the item's inventory, with the presence of item_id & item_quantity.
When we create a new purchase it'll automatically update the item_quantity in inventory table.
Here is the code inside the model's file
Item.rb has_one :inventory validates_presence_of :name after_create :create_inventory private def create_inventory Inventory.create(item_id:self.id, quantity: 0) end
Inventory.rb
belongs_to :item validates_presence_of :quantity, :item_id
Purchase.rb
validates_presence_of :item_id, :quantity after_create :update_inventory private def update_inventory @item = Item.find(self.item_id) @inventory = @item.inventory @inventory.update_column('quantity', @inventory.quantity+self.quantity) end
So, here is the Question :
I've an item with quantity of 100 and I want to update it's quantity in the inventory before purchasing more quantity for the same.
So, if I have to write the model spec for the purchase model then, how can I update item's inventory value to 100 after creating the item in the model spec ? Because there is no FactoryGirl method to update the records.
Experienced programmers are welcome to improve this question.

| Rails postgres sql view missing data when creating via migration Posted: 16 Oct 2016 03:42 AM PDT I've been speeding up some statistics reports in my rails(4.2.7, postgres 9.5 database) project via creating sql views. I wrote all code in PGAdmin, checked all data in views. Than I generated migration in my rails project and copied all written sql code to migration. When I run migration, all views are being created with randomly missing data. Example: create or replace view revenue_by_date as select sum(reward) as reward_coins, count(ot.id) as amount, (sum(reward)::float / substring(value from '---\s''(\d+)''')::bigint) as reward_dollars, ot.created_at::date as date from offerwall_transactions ot inner join settings on var = 'exchange_rate' where ot.reward > 1 group by ot.created_at::date, settings.value;
I get reward_dollars data missing.  However, when creating via PGA data is ok  I have same problems with other views. Some views are created with no data at all. Where is a mistake? |

Posted: 16 Oct 2016 05:02 AM PDT What are the steps and means of capturing microphone audio stream through HTML5 / Javascript (no flash) and then sending it to an already set up icecast server? The solution must be solely browser/web-based, no additional software. The server is on Rails 5.0.0.1. Where should I start? I'm struggling to find any relevant info online as everything talks about uploading/recording audio files as complete files, not streams. |

| Request spec with devise_token_auth + omniauth Posted: 16 Oct 2016 01:59 AM PDT I'm currently writing an API with Rails 5 using devise_token_auth and omniauth as authentication strategy. To check if the omniauth authentication works, I wrote a request spec: OmniAuth.config.test_mode = true OmniAuth.config.mock_auth[:facebook] = OmniAuth::AuthHash.new( { provider: 'facebook', uid: '123456' }) Rails.application.env_config["devise.mapping"] = Devise.mappings[:user] Rails.application.env_config["omniauth.auth"] = OmniAuth.config.mock_auth[:facebook] get '/omniauth/facebook/callback' expect(response).to have_http_status(:ok)
When I run the test I have to following error: NoMethodError: undefined method `[]' for nil:NilClass /Users/gaetan/.rvm/gems/ruby-2.3.1/gems/devise_token_auth-0.1.39/app/controllers/devise_token_auth/omniauth_callbacks_controller.rb:14:in `redirect_callbacks'
Here is the line 14: devise_mapping = [request.env['omniauth.params']['namespace_name'],
So I guess that's because omniauth.params is nil. Does it mean that I also have to mock the params? How? |
| Rails model to pull data from REST api and save to database Posted: 16 Oct 2016 01:33 AM PDT I'm making an app that needs to make an API request every 15 mins, put that data into a database, and put then load the data into highcharts objects. How do I generate a model that will have these values that will have corresponding table columns: id, calls_offered, calls_handled, timestamp Additionally how do I access that data to dynamically update the charts I have created? Bonus question: will that automatically pass over to Heroku when I deploy to it? |
| Rails - expecting <"categories/index"> but rendering with <[]> Posted: 16 Oct 2016 01:36 AM PDT I am trying to run a test but see the below error "CreateCategoriesTest#test_get_new_category_form_and_create_category [/Users/imcglobal/Desktop/RailsDevelopement/blog/test/integration/create_categories_test.rb:10]: expecting <"categories/index"> but rendering with <[]>" below are the test details test "get new category form and create category" do get new_category_path assert_template 'categories/new' assert_difference 'Category.count', 1 do post categories_path, category: {name: "sports"} end assert_template 'categories/index' **#line 10** assert_match "sports", response.body end #categories controller def index @categories = Category.all end
My index file loops through categories object. Can anyone please let me know what i am missing. Thanks. |
| Preventing adding duplicates to Cart Posted: 16 Oct 2016 01:21 AM PDT So here's the action that i'm testing out in my controller def add_to_cart @cart = current_cart if @cart.tutors.where(params[:tutor_id]).empty? @cart.add_tutor(params[:tutor_id]) flash[:success] = 'You have successfully added the tutor to your shortlist!' redirect_to show_path else flash[:danger] = 'You have already shortlisted the tutor!' redirect_to show_path end end
I'm not sure if this is the correct way to go about testing if tutor_id is present in the cart. I actually tried testing various methods of checking for the children's properties in rails console. I arrived at Parent.Child.where(:id => X) as a way to check if any of the children has id = X. This is what shows up in my server (or development log) when the method is called. Started POST "/add_to_cart/11" for 116.87.14.150 at 2016-10-16 07:32:09 +0000 Cannot render console from 116.87.14.150! Allowed networks: 127.0.0.1, ::1, 127.0.0.0/127.255.255.255 Processing by CartsController#add_to_cart as HTML Parameters: {"authenticity_token"=>"XzHaIJMzIz9I84W5tmLuj+28SBvVP9pc1JdZOyQaYEr286JNIw4J8tKtSON7eIWsdf0Lc6ogCdT2LrdtVVxGoA==", "tutor_id"=>"11"} cart_id = 17 Cart Load (0.2ms) SELECT "carts".* FROM "carts" WHERE "carts"."id" = ? LIMIT 1 [["id", 17]] (0.2ms) SELECT COUNT(*) FROM "tutors" INNER JOIN "cart_tutors" ON "tutors"."id" = "cart_tutors"."tutor_id" WHERE "cart_tutors"."cart_id" = ? AND (11) [["cart_id", 17]]
Anyway it constantly processes the else portion which means its not working like i meant it to be, which probably means that its not checking for the ID like i intend for it to do. Am i using the correct method? If not, how should i be doing it insteaD? |
| Rails ActiveRecord find a table attribute's value given conditions in 2 tables Posted: 16 Oct 2016 04:54 AM PDT I have 2 tables: - A conversations table that contains a list of conversations with their IDs (and two users ids associated to each ('recipient_id' and 'sender_id').
- A messages table that contains messages associated to one of the existing conversations. Every instance of Message includes a boolean attribute 'read' (defaults false) intended to show if there are any unread messages in a conversation.
So Conversation has_many :messages and Message belongs_to :conversation My objective is to check if the current_user has any unread messages (in any of his existing conversations) to display a general alert. So far I've managed to display an alert for each conversation but I'm struggling to find an efficient way to implement a general one. My original approach was to: - Find the last message in each of the current user's conversations.
- Evaluate if each of those last messages were sent by the current user AND if read == false.
- Return true if any of those last messages met these condition.
This translated into the following code: @conversations = current_user.conversations @unread = [] if @conversations.exists? @conversations.each do |conversation| if conversation.messages.exists? if conversation.messages.last.user_id != current_user.id && conversation.messages.last.read == false @unread << true end end end end @unread.include?(true) end
I'm quite new coding but it seems a pretty inefficient method having to loop through all current_users conversations and creating an array to check if there's any 'true' value on it. I'd loop through the messages themselves but an instance only has the user_id of the sender so if I don't link it with the Conversation model there's no way to know if a message was sent to him. Could you help with an efficient way to achieve this with a more appropriate Active Record query or a better approach. By the way, not sure if matters but I'm using postgresql in my dev environment.

| How to combine and sort arrays with jbuilder Posted: 16 Oct 2016 12:38 AM PDT I want to create two arrays that render different partials, then combine and sort them on an attribute, and add that array to a key in the response. a = json.array!([1,2,3]) do |company| json.value(company.to_s) # This is a different partial to below end b = json.array!([1,2,4]) do |person| json.value(person.to_s) # Different partial from above end ## Do something here
Result should be { stuff: [{:value=>"1"}, {:value=>"1"}, {:value=>"2"}, {:value=>"2"}, {:value=>"3"}, {:value=>"4"}] }
I tried this, but it does sort it json.stuff do (json.array!([1,2,3]) do |company| json.value(company.to_s) end + json.array!([1,2,4]) do |person| json.value(person.to_s) end).sort_by{|y| y[:value]} # (people_json + people_json) end
