Destroy path not working in comments but I can create a comment

Question

I cannot figure this out. Everything seems to be set up correctly. The create comments is working fine but when I try to destroy it gives me a missing template error. I've searched and tried about everything I can think of. Part of me thinks its a JS issue but when I look at my logs it appears to work fine. I'm using devise as well FYI. Any help would be amazing. Thanks.

Answer 1

Since you are talking about "JS issue", I assume you want the destroy action to be called by an AJAX request. Since the nested route looks fine and you also assigned the correct HTTP verb, but you missed to assign remote: true to the link to execute an AJAX request, like:

    <%= link_to 'Destroy Comment', [@pit, comment],
           method: :delete,
           remote: true,
           data: { confirm: 'Are you sure?' } %>

Furthermore: The reason why you end up in show action, is the resource URL for both requests is the same (so your nested route works fine). But the HTTP verb seems to be missed.
Please do:
1.) post the generated HTML link
2.) post the request header (especially X-Requested-With and Accept)
3.) disable all custom JS except jQuery in your application.js (restart your webserver in RAILS_ENV=development) and test if the delete request still fails
If disabling custom JS in your application.js works for the link, the search, which custom JS make it fail...
