This is really bugging me. My controller was working fine, but I have now changed the namespace and appear to be having issues with the paths or something. I tried editing the paths in accordance with rake routes but still no avail
here is the error:

I think it's because you have the syntax wrong. try adding this :method => :delete right now you have <%= link_to 'Eliminar', pelicula, method: :delete, data: { confirm: 'Estás seguro?' } %>. Below is a way to debug if request are being sent or not.
When your running your server locally check the logs in the terminal window.
Pressing enter a few times within the terminal, while the server is running will give you some negative space inbetween the last action a new action your app will preform.
After you've added some negitave space in the terminal, Go back to the app and press delete on the item.
Go back to your terminal and find the gap of space If you see
Started DELETE "/peliculas/{Some Number}"
Processing by PeliculasController#destroy as HTML
That means it's working.
I'm pretty sure it could be because your syntax after the 'Eliminar' is wrong change it to, :method => :delete instead of method: :delete
I am in entry level of Rails. I has made the database (whose name is "shop") with scaffold. Also I made the page which shows the overview of table and jumps to other page which shows the specific information of record.
Now I try to make the page that the specific information of record is shown in the same page of the overview of table when the "show" link on the one row of table is clicked.
However, despite of my expectation, it jumps to other page as I already have done.
I used many hours about this so would like to have someone's help.
Thank you.

If you have jquery rails in your gemfile (gem 'jquery-rails') and have:
//= require jquery
//= require jquery_ujs
in your application.js, what you've got there should work. Minus the show.js.erb, which would require you changing the data-type to be script instead of html. Although based on your description, the show.js.erb wouldn't be needed. The script you have in index.html.erb will suffice.
I am attempting to move one of my controllers (Testo) into the admin space, I have changed to route file as so:

end
Class name for the controller:

It gets called when this link gets pressed:
<%= link_to "Alex Link", alexes_path(#alex) %>
so I am assuming that the get-all part of the controller would get invoked, and I commented out lines in the controller that I thought would get invoked, but I still get this error:
undefined method `each' for nil:NilClass
from line 10:
7: <th></th>
8: </tr>
9:
10: <% #alexes.each do |alex| %>
11: <tr>
12: <td><%= link_to 'Show', alex %></td>
13: <td><%= link_to 'Edit', edit_alex_path(alex) %></td>
Any idea where the problem is happening?
Thanks!
<%= link_to "Alex Link", alexes_path(#alex) %>
