Destroy Action

keith · October 19, 2008, 8:40pm

Hi Everyone,

I have just created a destroy action in my controller, it was working
fine about 2 hours ago and now for some reason it has stopped working.
Once I click on destroy I receive ’ Unknown action No action
responded to destroy’. The action that I want it to redirect to is
‘list’ and this action does work as I have another action that
redirects to ‘list’ fine. Could anyone let me in to what I I have done
wrong please…?

def list
@albums = Album.find(:all)
render(:action => ‘album_list’)
end

def destroy
@album = Album.find(params[:id])
@album.destroy
redirect_to(:action =>‘list’)
end

And in my view I have

<% if @album != nil -%>
ID: <%= @album.id %>

Title: <%= @album.title %>

Artist: <%= @album.artist %>

Genre: <%= @album.genre %>

<% else -%>
No record found.

  <% end -%>
  <%= link_to('Back', :action => 'alt_album_list') %> |
  <%= link_to('Edit', :action => 'edit', :id => @album.id ) %> |
  <%= link_to('Destroy', {:action => 'destroy', id =>

@album.id}, :confirm => ’
Are you sure?’) %>

When I go into the logs I get the following error message

Has anyone came across this before? I have done research on the
message and someone has the same problem and fixed it by going into
the following

This is a comment I found from another group

I got this error (ActionController::UnknownAction - No action
responded to …), and I noticed it was because the link_to helper
generated bad URL’s (in the “:controller/:id/:action” format rather
than “:controller/:action/:id”).

The fix was to change the order of statements in the config/routes.rb
file; move my “map.resources” statements higher up in the file
(=higher priority).

Thanks everyone

Moving "map.resources: highest did not work for me i moved
map.resources :users to top but still my destroy method which was using
:method => ‘post’, did not work untill i add the following in my
routes.rb under the map.resources :users

map.connect ‘/users/:id/’, :controller => ‘users’, :action => ‘destroy’,
:id => /\d+/

, so the new routes.rb (without comments #) looked like following:

ActionController::Routing::Routes.draw do |map|
map.resources :users
map.connect ‘/users/:id/’, :controller => ‘users’, :action =>
‘destroy’, :id => /\d+/

map.connect ‘:controller/:action/:id’
map.connect ‘:controller/:action/:id.:format’
end

I hope that helps

sorry just tested while this short version fixes the ‘destroy’ method
but it breaks the ‘new’ method so you will have to use the above
mentioned full version which is:

map.connect ‘/users/:id/’, :controller => ‘users’, :action => ‘destroy’,
:id => /\d+/
