Rails Guides: Getting Started 5.13 Deleting Articles: Confirmation Dialog Box WON'T Appear

I am currently trying to get Rails to run on my Windows 7 machine and I am having difficulty. I am very new to Rails (inferred by my use of the Getting Started guide) and I am stuck on this:

http://guides.rubyonrails.org/getting_started.html#deleting-articles

Specifically the, you guessed it, confirmation dialog box. It never appears and Rails just utilizes a SHOW route.

Now for the code:

app\assets\javascripts\application.js

// This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts,
// or any plugin's vendor/assets/javascripts directory can be referenced here using a relative path.
//
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// compiled file.
//
// Read Sprockets README (https://github.com/rails/sprockets#sprockets-directives) for details
// about supported directives.
//
//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require jquery.ui.all
//= require_tree .

app\controllers\articles_controller.rb

class ArticlesController < ApplicationController
  def index
    @articles = Article.all
  end

  def show
    @article = Article.find(params[:id])
  end

  def new
    @article = Article.new
  end

  def edit
    @article = Article.find(params[:id])
  end

  def create
    @article = Article.new(article_params)

    if @article.save
      redirect_to @article
    else
      render 'new'
    end
  end

  def update
    @article = Article.find(params[:id])

    if @article.update(article_params)
      redirect_to @article
    else
      render 'edit'
    end
  end

  def destroy
    @article = Article.find(params[:id])
    @article.destroy

    redirect_to articles_path
  end

  private
    def article_params
      params.require(:article).permit(:title, :text)
    end
end

app\views\articles\index.html.erb

<h1>Listing Articles</h1>
<%= link_to 'New article', new_article_path %>

<table>
  <tr>
    <th>Title</th>
    <th>Text</th>
    <th colspan="3"></th>
  </tr>

  <% @articles.each do |article| %>
    <tr>
      <td><%= article.title %></td>
      <td><%= article.text %></td>
      <td><%= link_to 'Show', article %></td>
      <td><%= link_to 'Edit', edit_article_path(article) %></td>
      <td><%= link_to 'Destroy', article_path(article),
              method: :delete,
              data: { confirm: 'Are you sure?' } %></td>
    </tr>
  <% end %>
</table>

and app\views\layouts\application.html.erb

<!DOCTYPE html>
<html>
<head>
  <title>Blog</title>
  <%= stylesheet_link_tag    'default', media: 'all', 'data-turbolinks-track' => true %>
  <%= javascript_include_tag 'default', 'data-turbolinks-track' => true %>
  <%= csrf_meta_tags %>
</head>
<body>

<%= yield %>

</body>
</html>

<!--%= javascript_include_tag 'application', 'data-turbolinks-track' => true %-->

Now in the command line, when I click the, “link_to,” Destroy link, I get:

[2015-09-15 18:48:26] ERROR Errno::ECONNRESET: An existing connection was forcibly closed by the remote host. @ io_fillbuf - fd:10
    C:/RailsInstaller/Ruby2.1.0/lib/ruby/2.1.0/webrick/httpserver.rb:80:in 'eof?'
    C:/RailsInstaller/Ruby2.1.0/lib/ruby/2.1.0/webrick/httpserver.rb:80:in 'run'
    C:/RailsInstaller/Ruby2.1.0/lib/ruby/2.1.0/webrick/server.rb:295:in 'block in start_thread'
  Rendered C:/...

Note that everything seems normal after:

Rendered C:/

To fix this issue on my own, I have:

  • Made sure SQLite is on my machine
  • The SQLite gem is installed
  • Active scripts are turned on for my web browser (Opera; based on
    Chromium)

I have followed every piece of advice I could from Stack Exchange and Stack Overflow, including:

Modifying index.html.erb with:

<%= link_to 'Destroy',  post,  method: :delete, data: { confirm: 'Are you sure?' } %>

or:

link_to 'Cancel?', schedule_path(current_user.schedules[0]), :confirm => "are you sure?", :method => :delete

or:

<td><%= link_to 'Destroy', { action: :destroy, id: post.id }, method: :delete, data: { confirm: 'Are you sure?' } %></td>

or:

<td><%= link_to 'Destroy', [comment.post, comment], method: :delete, data: { confirm: 'Are you sure?' } %></td>
  • Making sure that because I am on Windows 7, that my CoffeeScript is
    version 1.8.0 and that I updated the Gemfile as such
  • Making sure the gem, “jquery-rails,” is included in the Gemfile file
  • Using method: destroy instead of method: delete
  • My rake routes look as they should. One answer mentioned making sure
    bin/rake routes returned something normal and it does

Making sure the application.js file includes:

//= require jquery
//= require jquery_ujs

(which you can see above that it does)

and nothing, NOTHING, has worked.

The only thing I have tried that has given me ANY success is replacing the link_to in index.html.erb with button_to.

But this doesn’t produce a confirmation window. It just performs a DESTROY.

I am very confused and I have spent many hours trying to get this to work.

I have found my answers from these links:

  • Rails CRUD – Destroy path always routes to the User show page
  • Rails-4, ExecJS::ProgramError in Pages#welcome
  • Rails, default.js is empty, and jquery and jquery_ujs not loaded
  • Rails 4 link_to Destroy not working in Getting Started tutorial

I may be missing a few links and answers, so please feel free to link me to a thread you think I may have missed.

Thank you for reading this MASSIVE wall of text and I hope I can find a solution to my problem soon.

    I don’t think the layout is loading your javascript properly.

    Try this. Hope it helps!
