| Rails get the parent from the AR relation of a has_many Posted: 19 Jul 2016 08:14 AM PDT I have a model Client which has_many :analytics and Analytic which belongs_to :client. I have written a method in the analytic model to update itself for a given client and basically want to call Client.find(xx).analytics.update_analytics(arg1, arg2,..) The code in Analytic.rb looks something like this: def self.update_analytics(arg1, arg2, ...) client = self.client end
The self.client errors out undefined method and self.parent just returns Object but I cannot call self.parent.id or other attributes from the parent. How do I get the Client instance that called the analytics.update_analytics method inside of it? |

| Replacing gem's vendor assets in Rails 5 Posted: 19 Jul 2016 08:00 AM PDT I'm trying out Trix (https://github.com/basecamp/trix) on my Rails 5 project using the Trix gem (https://github.com/maclover7/trix). In Rails 5, how do you go about replacing / overriding a gem's assets in the vendor directory. I've tried adding the following: vendor/assets/stylesheets/trix/trix.css vendor/assets/stylesheets/trix.css vendor/assets/stylesheets/trix/trix.scss vendor/assets/stylesheets/trix/trix.csss
My application's application.scss file contains @import "vars"; @import "trix"; # App is picking up the asset from the gem @import "header"; @import "post" @import "footer";
The same goes for vendor javascripts where I've tried creating a file in vendor/assets/javascript/trix/config/toolbar.coffee |
| Rails remote form not submitting with JS when signature-pad present Posted: 19 Jul 2016 07:59 AM PDT I have a rails form with remote: true which I submit after some processing with JavaScript. I do it using jQuery: $form.submit()
Everything works fine until I add https://github.com/thomasjbradley/signature-pad to the form (and some hidden inputs to send canvas data to the server). With signature-pad present form submitting stops working - there are no new requests in Network tab in Chrome developer console when I use the above method to submit the form. Calling .submit() on HTML element object instead of jQuery object $form[0].submit() submits the form in a regular way without AJAX. Method described in this post How to reliably submit an HTML form with JavaScript? also submits the form in a regular way without AJAX. |

| Rails: don't refresh page after modal action/submit Posted: 19 Jul 2016 07:47 AM PDT I have a modal which opens on top of another screen. The base screen has a filter method that uses AJAX to filter the results on that page. After, I filter the results on the screen, I can open the modal and perform an action on the form in the modal. However, I don't want to perform a redirect/refresh. How do I do this while still performing the submission? My modal link is like: <%= link_to this_path(user_id: user.id), class:"modal-link", data: {"modal-url" => this_path(user_id: user.id)} do %><span><i class="fa fa-plus"></i><% end %>
The modal is standard enough: <div class="modal form-modal"> <div class="modal-container"> <div class="modal-dialog modal-dialog-wide"> <button class="close">×</button> <div class="modal-content"> <div class="modal-header"> <h2 class="hdg-b">Edit This</h2> </div> <div class="modal-body"> <div id="error_explanation"></div> <%= render 'form', form_path: action_path, form_method: :put, create: false %> </div> </div> </div> </div> </div>
The AJAX is too: MyProject.onPageLoad(function() { var form = $('.edit_site_scope'), onSubmit = function(event) { //callback handler for form submit event.preventDefault(); var form = $(this), url = form.attr("action"), //get form action: type = form.attr("method"), data = form.serialize(); var location = window.location.href; var posting = $.ajax({ type: type, url: url, data: data, dayaType: "json", success:function(data, textStatus, jqXHR) { $('.modal').remove(); window.location = location; $('#contact-tab-submit').show(); }, error: function(jqXHR, textStatus, errorThrown) { $('#error_explanation').html(''); errors = jqXHR.responseJSON; $.each( errors, function( key, value ) { $('#error_explanation').append('<div class="alert alert-dismissable" id="alert-message"><i class="fa fa-exclamation-triangle"></i>' + value + '<div class="alert-close">Close</div></div>'); }); $('#contact-tab-submit').show(); } }); window.setTimeout(function() { $(".alert").fadeTo(500, 0).slideUp(500, function(){ $(this).remove(); }); }, 5000); return false; // prevent default when submit button clicked }; if (form.size() !== 0) { form.submit(onSubmit); } });
And here is my controller action on the form submit: def action_to_be_performed @this_thing = ThisThing.where(id: params[:id]).first @this_thing.update(this_things_params) flash[:success] = "Successfully performed the action." render json: @this_thing rescue => error Rails.logger.error "Exception caught updating this.\nCause: #{error}\n" + error.backtrace.join("\n") render json: @this_thing.errors.full_messages, status: :bad_request end
I really struggle with modals still and I guess with AJAX. How do I perform my action, close the modal and keep the current page open? |

| Making ActiveRecord sanitization methods available in class Posted: 19 Jul 2016 07:34 AM PDT I am building a filter class that constructs special sql queries. It's a service class, not a model and has no underlying table. I want to sanitize the input when embedding it into the sql, to safeguard against injection.
These methods do exactly what I want: http://api.rubyonrails.org/classes/ActiveRecord/Sanitization/ClassMethods.html However, using include ActiveRecord::Sanitization does not work. When I call sanitize_sql_array it complains: Undefined local variable or method `connection` Applications::ApplicationFilter:Class
Which is seemingly some kind of dependency issue. When I inherit my filter class from AR, with Applications::ApplicationFilter < ActiveRecord::Base, then it works. But I don't want to do that.. please.. please please please Does anyone know how to make this sanitize_sql_array method available without inheriting from the whole big lumpy activerecord rhinoserous? |

| Can you embed forms and associate elements with specific form Posted: 19 Jul 2016 07:17 AM PDT I have a table whereby there are two columns containing checkboxes, one for approving and declining. My intention is that you can either approve or reject a row by clicking the associated checkbox and then clicking the reject or approve buttons at the bottom. The problem is I am generating the table through iteration and the way my code is structured means that a form is being generated for every row. - @campaigns.each do |campaign| %tr.medium %td= link_to campaign.name %td= campaign.created_at %td= campaign.service %td= campaign.price %td= campaign.freq %td= campaign.start_date %td= campaign.revenue %td= campaign.status %td %form{:name => "approve_path", :id => campaign, :method => "post", :enctype => "text/plain"} = check_box_tag 'campaigns[]', campaign.id, false, {id: "c#{campaign.id}", class: "approvedservices"} %td %form{:name => "reject_path", :id => campaign, :method => "put", :enctype => "text/plain"} = check_box_tag 'campaigns[]', campaign.id, false, {id: "c#{campaign.id}", class: "rejectedservices"} %tr.medium %td.white{:colspan => 8} %td.white %span.input-group-btn %button.btn.btn-success#approvedservicesbutton{:type => "submit", :style => "width: 100%; height:34px;", "data-toggle" => "tooltip", title: "Approve"} %td.white %span.input-group-btn %button.btn.btn-danger#rejectedservicesbutton{:type => "submit", :style => "width: 100%; height:34px;", "data-toggle" => "tooltip", title: "Reject"}
As you can see the way I have it structured means for every row a new form is created and the submit buttons are not associated so I'm slightly perplexed with the required nesting how I could achieve this. |
| What happends when a perform_async is called but sidekiq is not running? Posted: 19 Jul 2016 07:21 AM PDT I was wondering what happends when a perform_async is called on a worker but sidekiq (bundle exec sidekiq) isn't running ? In my app I have some observers that ask sidekiq to do a job when one of my models is trigger (ie create, update or destroy in some cases). I also have a rake task that builds me a database from some data I have.. When this task is running, it creates several records that trigger my observers who then push jobs in sidekiq queue. For testing purpose I ran this task without turning on sidekiq and it's working fine, my data is being pushed in mysql ! I know ask myself what is happening to the job my observer tells my worker to do ? Is it still done ? Is it done but not asynchronously ? Is it not done ? |
| Possible to render and raise exception in Rails controller? Posted: 19 Jul 2016 07:07 AM PDT I have been fighting with this for some hours now. I have a controller action that I want to render a page and then raise an exception automatically. I couldn't find much information on this that makes me think that I am looking for the wrong thing. Is something like the below possible? class UsersController < ActionController::Base def new # .. do stuff begin UserMailer::send_confirmation_link(@user) rescue StandardError => e render 'email_error' raise(e) end # .. other stuff end end
In this case I simply want to inform the end-user of the error and then raise the exception on the application itself. Notice that I can't change the de-facto error page since this is a smaller application in the same codebase with a bigger application. |

| How to sort list using Angular Sortable and Rails Posted: 19 Jul 2016 07:46 AM PDT I'm stuck with this problem. I;ve built an API in Rails and a client in Angular. I've got a model called Todo which has a property called order. When I create a new Todo, I automatically assign the newly created todo a value order like so: @todo = Todo.create(todo_params) @todo.order = Todo.count + 1
And to display all todos: @todos = Todo.where(...).order(:order.desc)
In my client I'm using Sortable for the UI manipulation and there's a method called onUpdate which gives me the new indexes for the array. The problem I'm having is that the indexes are considerably different than the value I've in the order property. When the aforementioned function is called I get the item and two more values: newIndex and oldIndex, but the problem is that this doesn't give me the index of the other todos, so how can I reorganise this on the database? I'd appreciate any help as I'm a bit at loss here. PS: Please note this is Rails API only, so no views. EDIT Output wanted: Let's imagine this: I have three items in the database: {name: A, order: 1}, {name: B, order: 2}, {name: C, order: 3}. In the front-end, while using ng-repeat, each item will have an $index. Let's say for argument sake that A will have $index value of 0, B 1, C 2. At the moment, when I use the Angular library Sortable, when I manually sort the list, I get the values: oldIndex and newIndex which corresponds to the position of the item I've moved within the array, but it does not shows the position of all items within array, so I don't know how to use the properties these values to update the object in the database. |
| No route matches {:action=>"/microposts", :controller=>"microposts", :params=>{:micropost=>{:content=>"Lorem ipsum"}}} Posted: 19 Jul 2016 06:50 AM PDT I am currently stuck on the rails tutorial from Michael Hartl (railstutorial.org), Chapter 13 and getting the following two errors: 1) Error: MicropostsControllerTest#test_should_redirect_create_when_not_logged_in: ActionController::UrlGenerationError: No route matches {:action=>"/microposts", :controller=>"microposts", :params=>{:micropost=>{:content=>"Lorem ipsum"}}} test/controllers/microposts_controller_test.rb:11:in 'block (2 levels) in <class:MicropostsControllerTest>' test/controllers/microposts_controller_test.rb:10:in 'block in <class:MicropostsControllerTest>' 2) Error: MicropostsControllerTest#test_should_redirect_destroy_when_not_logged_in: ActionController::UrlGenerationError: No route matches {:action=>"/microposts/499495288", :controller=>"microposts"} test/controllers/microposts_controller_test.rb:18:in 'block (2 levels) in <class:MicropostsControllerTest>' test/controllers/microposts_controller_test.rb:17:in 'block in <class:MicropostsControllerTest>'
As far as i know, 'action' should be something like get, post, delete etc. But i don't know, why it says 'micropost' here. Content of microposts_controller_test.rb: require 'test_helper' class MicropostsControllerTest < ActionController::TestCase def setup @micropost = microposts(:orange) end test 'should redirect create when not logged in' do assert_no_difference 'Micropost.count' do post microposts_path, params: {micropost: {content: 'Lorem ipsum'}} end assert_redirected_to login_url end test 'should redirect destroy when not logged in' do assert_no_difference 'Micropost.count' do delete micropost_path(@micropost) end assert_redirected_to login_url end end
Content of micropost_controller.rb: class MicropostsController < ApplicationController before_action :logged_in_user, only: [:create, :destroy] def create @micropost = current_user.microposts.build(micropost_params) if @micropost.save flash[:success] = 'Micropost created!' redirect_to root_url else render 'static_pages/home' end end def destroy end private def micropost_params params.require(:micropost).permit(:content) end end
Content of routes.rb: Rails.application.routes.draw do root 'static_pages#home' get '/help' => 'static_pages#help' get '/about' => 'static_pages#about' get '/contact' => 'static_pages#contact' get '/signup' => 'users#new' get '/login' => 'sessions#new' post '/login' => 'sessions#create' delete '/logout' => 'sessions#destroy' resources :users resources :account_activations, only: [:edit] resources :password_resets, only: [:new, :create, :edit, :update] resources :microposts, only: [:create, :destroy] end
Any help is appreciated. Thanks Edit: In micropost_controller_test.rb, it should've been: class MicropostsControllerTest < ActionDispatch::IntegrationTest
instead of class MicropostControllerTest < ActionCntroller::TestCase

| Assiging values in Ruby using PHP equivalent for loop (I'm using Ruby on Rails) Posted: 19 Jul 2016 05:28 AM PDT I have a unsolved issue on stackoverflow which I suspect to be due to incorrect syntax of for loop on Ruby language. I would like to ask what is the equivalent of the following in Ruby: for ($x = 0; $x <= 10; $x++) { $array[] = $x; }
Thanks in advanced for helping! Please help me solve my initial question in the link above. Many thanks! |
| Rails bootstrap delete confirmation with modal Posted: 19 Jul 2016 06:05 AM PDT I want to do a bevore action while clicking on a link. It should display a bootstrap modal with cancel and delete button. code lookslike this: Delete Button <button class="btn btn-default" data-href="<%= url_for(:action => :delete, :id => @vid.id) %>" data-toggle="modal" data-target="#modalBox"> <i class="fa fa-trash"></i> <%= t "movies.add.delete" %> </button>
Modal Code is in application.html.erb -> modal is empty. I set the buttons on page load with jquery. that works fine. $(".modal-footer").html("<button type='button' class='btn btn-default' data-dismiss='modal'>Cancel</button> <a class='btn btn-danger btn-ok'>Delete</a>");
and the code for the modal to wait is this: $("#modalBox").on('show.bs.modal', function(e) { $(this).find('.btn-ok').attr('href', $(e.relatedTarget).data('href')); });
whats my problem in this case? I've got the code example from here: http://plnkr.co/edit/NePR0BQf3VmKtuMmhVR7?p=preview thanks Problem is: Modal is shown for less than 100ms ^^ .. and the deletion is performed |
| Rspec test got: nil Posted: 19 Jul 2016 05:25 AM PDT I'm trying to do a basic rspec test, which looks like this; require 'rails_helper' describe ReviewsController do describe "GET #index" do it "assigns a new review to @reviews" do review = Review.create( rating: 4 ) get :index expect(assigns(:review)).to eq([review]) assert_response :success end end end
But I'm getting the failure: expected: Review id: 8, rating: 4, created_at: "2016-07-19 11:58:28", updated_at: "2016-07-19 11:58:28", user_id: nil, game_id: nil got: nil My ReviewsController looks like this: class ReviewsController < ApplicationController def index @reviews = Review.all end def show @review = Review.find(params[:rating]) end def create review = Review.new(review_params) respond_to do |format| if @review.save format.html { redirect_to root_url, notice: 'Review was successfully updated.' } format.json { render :show, status: :ok, location: @review } else format.html { render :new } format.json { render json: @review.errors, status: :unprocessable_entity } end end end private def post_params params.require(:post).permit(:message) end end
In case you need it, here's the review model: class Review < ActiveRecord::Base belongs_to :user belongs_to :game validates_presence_of :rating validates_uniqueness_of :user_id end
I don't understand why it's asking for a user_id or game_id, because it's only about the reviews.. |
| Devise authentication for polymorphic solution Posted: 19 Jul 2016 05:19 AM PDT Consider an application, which needs to have two different types of user: User as in standard clientOrganization as an entity offering some services through the application Requirements: - different standard controllers (sessions, registrations etc)
- access to different parts of the application of course
This seems like a walk in the park by simply creating two separate models with devise, but I really wouldn't like to duplicate so much functionality for authentication. I went with a polymorphic association, where Organization and User are different models, both with a 1-1 relation with Entity representing authentication. Entity only has devise attributes (like password etc), while others have type-specific ones. Unfortunately this solution comes with a lot of drawbacks, like having to define custom helpers, warden strategies and devise failure apps. I'm wondering, is there a concise solution for this type of issue? Ideally, something like having two devise models delegating everything regarding authentication to a separate entity. |
| Rails has_and_belongs_to_many query for all records Posted: 19 Jul 2016 05:26 AM PDT Given the following 2 models class PropertyApplication has_and_belongs_to_many :applicant_profiles end class ApplicantProfile has_and_belongs_to_many :property_applications end
I have a query that lists all property_applications and gets the collection of applicant_profiles for each property_application. The query is as follows and it is very inefficient. applications = PropertyApplication.includes(:applicant_profile).all.select |property_application| do property_application.applicant_profile_ids.include?(@current_users_applicant_profile_id) do
assume @current_users_applicant_profile_id is already defined. How can I perform one (or few) queries to achieve this? I want to achieve something like this PropertyApplication.includes(:applicant_profile).where('property_application.applicant_profiles IN (@current_users_applicant_profile))
