Destroy link in Rails 3.2 shows the data instead of deleting it

I created a new scaffold rails generate scaffold scores score:integer route_id:integer and ran rake db:migrate.

This works well, but when I go to the scores page to delete some data the delete link somehow displays the view details, but doesn't delete it. I also compared the link with some other projects and it looks pretty much the same only that it doesn't work this time.

That's what I have in my index.html.erb page:

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

I found in some posts on this site that the gem file needs to contain gem 'jquery-rails' so I checked and it is there. I also ran bundle install again, but no change. The change from link_to to button_to didn't help either.

Does anybody have an idea what else it could be? If you need more details let me know and I will be happy to add it.

Many thanks.

I had the same problem and I have managed to solve it only after I have added both jquery and jquery_ujs to my page:

<%= javascript_include_tag "jquery" %>
<%= javascript_include_tag "jquery_ujs" %>
<%= javascript_include_tag "application" %>

I most probably have a problem with the asset pipelines as I have requested both of them in the application.js but it didn't work when they were not explicitly requested on the page. In my application.js I have:

//= require_jquery
//= require_jquery_ujs
//= require_tree .

Simple. You need to include jquery_ujs also named as rails.js in your application.html.erb. I have this issue before. Rails needs rails.js to do this.

Sometimes it happens because you haven't included jquery_ujs in your application. Ope the browser console and check if jquery_ujs is included or if it is included multiple times.

I'm guessing that the method: :delete is being overridden or ignored since you're providing the resource. Could you try this?

<td><%= link_to 'Destroy', destroy_score_path(score), data: { confirm: 'Are you sure?' } %></td>

Here is the documentation for link_to for reference: http://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html#method-i-link_to
