Menu
I am sorry for asking what may be a remedial question, but in learning rails i was trying to follow along note for note in this tutorial:
http://guides.rubyonrails.org/getting_started.html
I posted a similar question from this tutorial last night and got a prompt response which helped me significantly, so I am hoping for the same. Thank you in advance.
Section 5.14: Deleting Posts
I am instructed to add a delete link to the index.html.erb page
<h1>Listing Posts</h1>
<table>
<tr>
<th>Title</th>
<th>Text</th>
<th></th>
<th></th>
<th></th>
</tr>
<% @posts.each do |post| %>
<tr>
<td><%= post.title %></td>
<td><%= post.text %></td>
<td><%= link_to 'Show', post_path %></td>
<td><%= link_to 'Edit', edit_post_path(post) %></td>
<td><%= link_to 'Destroy', post_path(post),
method: :delete, data: { confirm: 'Are you sure?' } %></td>
</tr>
<% end %>
</table>
which generates:
<td><a data-confirm="Are you sure?" data-method="delete" href="/posts/1" rel="nofollow">Destroy</a></td>
It looks OK to me, but when I click on the link I get neither the confirmation nor am I directed to the delete action. It generates this HTTP action
Request URL:http://localhost:3000/posts/1
Request Method:GET
Status Code:200 OK
Rails: 4, Ruby: 2, 64 bit windows 8, chrome: Version 28.0.1500.72 m
Thank you again
Adding the application.html.erb
<!DOCTYPE html>
<html>
<head>
<title>Listing</title>
<%= stylesheet_link_tag "application", media: "all", "data-turbolinks-track" => true %>
<%= javascript_include_tag :application %>
<%= csrf_meta_tags %>
</head>
<body>
<%= yield %>
</body>
</html>
which yielded this error:
ExecJS::RuntimeError in Posts#index Showing C:/Ruby-Projects/listing/app/views/layouts/application.html.erb where line #6 raised:

Make sure you have
//= require jquery
//= require jquery_ujs
into application.js file and application.js file is included into view/layout/application.html.erbfile
166
OK i needed to remove these two lines from application.js
//= require turbolinks
//= require_tree .
which got rid of the ExecJS run time error. Why were these included by default, and should I be figuring out why they were causing an error in the first place?
FWIW - the delete functionality now works.
