| Why can't I get /comments/new.html.erb? Posted: 03 Oct 2016 08:04 AM PDT I created models by scaffold command class Post < ActiveRecord::Base has_many :comments, as: :commentable end class Comment < ActiveRecord::Base belongs_to :commentable , polymorphic: true end ...

| call method of a controller from different controller view Posted: 03 Oct 2016 08:16 AM PDT The idea that when the user filling the booking info, he need to verify his phone number in the form where he receive the code and put it with rest of booking info before submitting , so I have the following view <%= form_for(@booking) do |f| %> <%= current_or_not_authenticated_user.email %> <br> <%= f.label :patient_id %> <%= f.collection_select :patient_id, User.order(:created_at), :id, :email %> <button type="button" class="btn btn-primary btn-md" data-toggle="modal" data-target="#patientModal"> New Patient </button> <br> <div class="form-group"> <%= f.label :type %> <%= f.select :booking_type, options_for_select([['Physiologist'], ['Psychiatrist'], ['Pediatrician']]) %> <%= f.hidden_field :customer_id, :value => current_or_not_authenticated_user.id %> </div> <div class="form-group"> <%= f.label :address %> <%= f.collection_select :address_id, Address.where(user_id: current_or_not_authenticated_user.id), :id, :address1 %> <button type="button" class="btn btn-primary btn-md" data-toggle="modal" data-target="#addressModal"> New Address </button> <% if current_user && !current_user[:verified_by_phone_at] %> <div class="form-group"> <%= label_tag(:phone) %> <%= text_field_tag(:phone) %> <button id="smsBtn" type="button" class="btn btn-primary">Send SMS</button> </div> <div class="form-group"> <%= label_tag :code %> <%= text_field_tag :code %> </div> <% end %> <%= f.submit "Confirm Booking" %> </div> <br> <% end %> <script> $(document).ready(function () { $('#smsBtn').on('click', function () { $.ajax({ url: <%=phone_verification_index_path %>, type: 'ajax', data: $('#code').val() }); }); }); </script>
clicking on smsbtn should go to phone_verification controller which in turn call third party method that send sms to the user, then the user fill his code and click on submit. my problem is when the user click on smsbtn, the @booking form get submitted and I don't want to form submit unless the user click on Confirm Booking, the only way that my jquery was working, was when I moved both phone field and smsbtn outside form. the order of the fields is important because I don't want the user to find code field first then phone field under it. |

| Collecting text submitted in input field with ember-rails Posted: 03 Oct 2016 07:27 AM PDT I am following an ember-rails tutorial. It's using coffeescript and I'm writing in javascript. Essentially I have a form that when I submit text on it it should place the text below. My controller looks like this: Emberapp.ApplicationController = Ember.Controller.extend({ entries: [], actions: { addEntry: function(){ this.entries.pushObject name: this.get('newEntryName'); this.set('newEntryName', ""); } } });
My template looks like this <div id = "container"> <h1>Emberails</h1> {{ input value=newEntryName enter='addEntry' }} <ul> {{#each entries}} <li>{{name}}</li> {{/each}} </ul> </div>
When I reload the page I get an error stating that 'name: this.get('newEntryName');' is an Unexpected identifier. I've been checking for the syntax rules online but I'm not sure if it is a coffeescript to javascript error or something else. |

| Creating model and nested model (1:n) at once with ActiveRecord Posted: 03 Oct 2016 06:54 AM PDT My Rails5 application has an organization model and a user model (1:n relationship). The workflow of creating an organization should include the creation of the organization's first user as well. I thought this would be able with ActiveRecord through nested models, however the create action fails with the error message "Users organization must exist". class Organization < ApplicationRecord has_many :users, dependent: :destroy accepts_nested_attributes_for :users end class User < ApplicationRecord belongs_to :organization end class OrganizationsController < ApplicationController def new @organization = Organization.new @organization.users.build end def create @organization = Organization.new(organization_params) if @organization.save redirect_to @organization else render 'new' end end def organization_params params.require(:organization).permit(:name, users_attributes: [:name, :email, :password, :password_confirmation]) end end
In the view I use the <%= f.fields_for :users do |user_form| %> helper. Is this a bug on my side, or isn't this supported by ActiveRecord at all? Couldn't find anything about it in the rails guides. After all, this should be (theoretically) possible: First do the INSERT for the organization, then the INSERT of the user (the order matters, to know the id of the organization for the foreign key of the user). |

| rails - list of tenants to migrate appears to be empty when loading a schema Posted: 03 Oct 2016 06:28 AM PDT what does it mean if in rails I run db:schema:load, and the schema loads until it says that "the list of tenants to migrate appears to be empty"? And what ways are available to solve this? As in here (sorry I am unable to format it better): ... --create_table("users", {:force=>:cascade})
-> 0.4490s -- create_table("web_migrations", {:id=>false, :force=>:cascade})
-> 0.6138s -- initialize_schema_migrations_table()
-> 0.0332s [WARNING] - The list of tenants to migrate appears to be empty. This could mean a few things: 1. You may not have created any, in which case you can ignore this message 2. You've run `apartment:migrate` directly without loading the Rails environment * `apartment:migrate` is now deprecated. Tenants will automatically be migrated with `db:migrate` Note that your tenants currently haven't been migrated. You'll need to run `db:migrate` to rectify this.

| Sorting based on multiple submodel conditions/states Posted: 03 Oct 2016 07:26 AM PDT I have a Room model that has_many Intervals. Intervals has a start_date and end_date attributes. I want to order the Rooms based on the following conditions 1- Room with no intervals 2- Room with any interval(s) with start_date > Date.today 3- Room without any intervals with start_date > Date.tody I want to sort the Rooms in such a way that Rooms satisfying 1 come first then Rooms satisfying 2 then 3 using a postgresql query not a method on the model. While I have no problem finding out which Rooms have no intervals using the query/scope below joins("LEFT OUTER JOIN intervals ON rooms.id = intervals.room_id").where("intervals.id is NULL")
I am having issues ordering by the 3 conditions in a single query, I tried the following Room.joins("LEFT OUTER JOIN intervals ON rooms.id = intervals.room_id").order("CASE WHEN intervals.id IS NULL THEN 1 END ASC")
The issue with this query is that if you call distinct on it you get the error PG::InvalidColumnReference: ERROR: for SELECT DISTINCT, ORDER BY expressions must appear in select list, the other issue even when you call distinct here and it works properly you would have sorted by only one condition which is the first 1. My idea is to generate a function with case conditional to give a value of generated column based on the 3 conditions and give the first the value 1, the second value 2, and the third value 3 and sort by this computed value, whenever I try it though I get hit by the error mentioned above. Any help would be appreciated. This is my trial to combine all 3 conditions: Room.joins("LEFT OUTER JOIN intervals ON rooms.id = intervals.room_id").group("room.id").order("CASE WHEN room.id IS NULL THEN 1 WHEN COUNT(CASE WHEN intervals.start_date > '#{Date.today.to_s(:db)}' THEN 1 END) > 0 THEN 2 WHEN COUNT(CASE WHEN intervals.start_date > '#{Date.today.to_s(:db)}' THEN 1 END) = 0 THEN 3 END")
This however gives the error: PG::GroupingError: ERROR: column "intervals.id" must appear in the GROUP BY clause or be used in an aggregate function Any help would be appreciated. |

| Link two attributes to one form element Posted: 03 Oct 2016 04:13 AM PDT I want to be able to have one select which specifies the value of two model attributes. Therefore if you were to select "yes" on a drop-down it would set the value of attribute a and attribute b to "yes" when the form is submitted. Although the below doesnt work it might help explain what I mean: = f.select :trial, :free , [['Yes', 'true'], ['No', 'false']], {}, class: 'selectpicker mandatory'

| Rails new object with store_accessor and Postgresql jsonb fails Posted: 03 Oct 2016 04:04 AM PDT I have a model Car which has a jsonb field for extra data. class Car < ApplicationRecord store_accessor :data, :extra_options end class AddDataToCars < ActiveRecord::Migration[5.0] def change add_column :cars, :data, :jsonb, null: false, default: '{}' add_index :cars, :data, using: :gin end end
I can seed my table with: car = Car.create!({ make: 'Lada', model: 'Niva', data: { extra_options: 'Some options' } })
and then get and set the extra_options field with: car.extra_options # => "Some options" car.extra_options = "Other options" # => "Other options"
However I cannot create a new object and then straight away set the extra_options field car = Car.new # => #<Car id: nil, make: nil, model: nil, created_at: nil, updated_at: nil, data: "{}"> car.extra_options = "Some option" # IndexError: string not matched # ...
I can do car.data = { extra_options: 'options' } # => {:extra_options=>"options"} car.extra_options # => "options"
But I would like the extra_options field to behave like a normal field so I can easily use it in my views like <%= form_for(rating) do |f| %> <%= f.label :extra_options %> <%= f.text_field :extra_options %> <% end %>
Is that at all possible? If not, how do I create a text field in the view that writes to the extra_options field? |
| force capistrano to use bundle exec on sidekiq start Posted: 03 Oct 2016 03:54 AM PDT I use capistrano-sidekiq. bundle exec cap production sidekiq:start

| Form submit button not showing Posted: 03 Oct 2016 03:57 AM PDT I'm working on a project where I'm trying to implement a voting system, but I'm having some trouble, I've tried creating a form with a hidden field: <% form_for :vote, url: votes_path do |f| %> <%= f.hidden_field :rating, value: '1' %></td> <%= form_submit_button("vote 1") %> <% end %>
But when I run that the submit button does not appear, I'm not really sure what I'm doing wrong. |
| Rails associated models with radio buttons Posted: 03 Oct 2016 03:46 AM PDT I have a boat model and I would like to show to user water sports equipment. User can select either available or optional radio button in boat#new action. But the problem is I could not find how to associate them. Here how it will look like; 
Then for boat#show action I would like to show whether they are available or optional. I do not want to put; has_one :canoe has_one :fishing equipment has_one : wakeboard ...
to boat model for every each of the water sport. How can I do that in an efficient way? |
| ActionCable delete message Posted: 03 Oct 2016 03:45 AM PDT I followed this tutorial to create a chat with ActionCable and Devise: https://www.sitepoint.com/create-a-chat-app-with-rails-5-actioncable-and-devise/ But it's essential, that a message can be deleted too. How can this be done, so that the message is disapearing from all the userscreens simultaniously. Here are my files: rooms.coffee jQuery(document).on 'turbolinks:load', -> messages = $('#messages') if $('#messages').length > 0 messages_to_bottom = -> messages.scrollTop(messages.prop("scrollHeight")) messages_to_bottom() App.global_chat = App.cable.subscriptions.create { channel: "ChatRoomsChannel" chat_room_id: messages.data('chat-room-id') }, connected: -> # Called when the subscription is ready for use on the server disconnected: -> # Called when the subscription has been terminated by the server received: (data) -> messages.append data['message'] messages_to_bottom() send_message: (message, chat_room_id) -> @perform 'send_message', message: message, chat_room_id: chat_room_id $('#new_message').submit (e) -> $this = $(this) textarea = $this.find('#message_body') if $.trim(textarea.val()).length > 1 App.global_chat.send_message textarea.val(), messages.data('chat-room-id') textarea.val('') e.preventDefault() return false
message_broadcast_job.rb class MessageBroadcastJob < ApplicationJob queue_as :default def perform(message) ActionCable.server.broadcast "chat_rooms_#{message.guild.id}_channel", message: render_message(message) end private def render_message(message) MessagesController.render partial: 'messages/message', locals: {message: message} end end
chat_rooms_channel.rb class ChatRoomsChannel < ApplicationCable::Channel def subscribed stream_from "chat_rooms_#{params['chat_room_id']}_channel" end def unsubscribed # Any cleanup needed when channel is unsubscribed end def send_message(data) current_user.messages.create!(body: data['message'], guild_id: data['chat_room_id']) end end
message.rb class Message < ApplicationRecord belongs_to :user belongs_to :guild validates :body, presence: true, length: {minimum: 2, maximum: 1000} def timestamp created_at.strftime('%H:%M:%S %d %B %Y') end after_create_commit { MessageBroadcastJob.perform_later(self) } end
I want to have a destroy_link on every message. |
| Rails 5 - implement reusable comment model - views? Posted: 03 Oct 2016 03:01 AM PDT In my app that I am building to learn RoR, I have a similar situation like this question. Now my question is how to change my views for this? I have an Annotation model, a Document model and a Comment model. If I switch to a polymorphic association such that my Annotations and my Documents can have Comments, how to do the view (in the partial)? This is the current partial: <%= simple_form_for([@annotation, @annotation.comments.build], html: { class: 'form-vertical', multipart: true }) do |f| %> <%= f.error_notification %> <%= f.input :commenter, :as => :hidden, :input_html => { :value => current_user.username }, label: false %> <%= f.input :body, placeholder: 'comment', focus: true, label: false %> <%= f.button :submit, 'Save' %> <% end -%>

| Create a model record when a button is pressed Posted: 03 Oct 2016 03:18 AM PDT I'm working on a project, and I'm trying to implement a feedback system. There are three buttons, positive, neutral and negative and at the moment when the user clicks a button they are asked if they want to submit more feedback and are taken to the new feedback form. However instead what I want is that when a button is pressed a record is saved with the rating field of the model set by which button they pressed. Then when a user gives more feedback they are taken to the edit page for that feedback. I'm not really sure how to go about doing this, would I need some javascript on the buttons? or does rails have a method that will do this? Thank you |
