Hi Raul,
I did as you suggested without editing the routes.rb file and I still
managed to come up the ' Unknown action No action
responded to destroy'
<%= link_to 'Destroy', {:action => 'destroy', id =>
@album.id},
:confirm => 'Are you
sure?',
:method => :delete %>
However I did managed to find another comment with the same type of
issue, which was
<%= link_to 'Destroy', movie, :confirm => 'Are you sure?', :method
=> :delete %> which was from
http://fairleads.blogspot.com/2008/01/this-is-second-part-of-my-series.html.
With this information I replace the following
# replace the line
<%= link_to 'Destroy', {:action => 'destroy', id =>
@album.id},
:confirm => 'Are you
sure?',
:method => :delete %>
# with
<%= link_to 'Destroy', @album, :confirm => 'Are you sure?', :method
=> :delete %>
And I added in the following into my routes.rb file
ActionController::Routing::Routes.draw do |map|
map.resources :albums
map.connect '/public/destroy/:id', :controller => 'public', :action
=> 'destroy' ~# New line added
# The priority is based upon order of creation: first created ->
highest priority.
# Sample of regular route:
# map.connect 'products/:id', :controller => 'catalog', :action =>
'view'
# Keep in mind you can assign values other than :controller
and :action
# Sample of named route:
# map.purchase 'products/:id/purchase', :controller =>
'catalog', :action => 'purchase'
# This route can be invoked with purchase_url(:id => product.id)
# Sample resource route (maps HTTP verbs to controller actions
automatically):
# map.resources :products
# Sample resource route with options:
# map.resources :products, :member => { :short => :get, :toggle
=> :post }, :collection => { :sold => :get }
# Sample resource route with sub-resources:
# map.resources :products, :has_many =>
[ :comments, :sales ], :has_one => :seller
# Sample resource route with more complex sub-resources
# map.resources :products do |products|
# products.resources :comments
# products.resources :sales, :collection => { :recent => :get }
# end
# Sample resource route within a namespace:
# map.namespace :admin do |admin|
# # Directs /admin/products/* to Admin::ProductsController (app/
controllers/admin/products_controller.rb)
# admin.resources :products
# end
# You can have the root of your site routed with map.root -- just
remember to delete public/index.html.
map.root :controller => "albums"
# See how all your routes lay out with "rake routes"
# Install the default routes as the lowest priority.
map.connect ':controller/:action/:id'
map.connect ':controller/:action/:id.:format'
end
However it seems to be working but when I do confirm to delete it
redirects me to another action by default being :controller =>
"albums" and this is set in my routes.rb file like so
# You can have the root of your site routed with map.root -- just
remember to delete public/index.html.
map.root :controller => "albums"
How can I amend this so it can redirect it to my action I want it to
go to?
I have copied in my Controller
class PublicController < ApplicationController
def album_list
@albums = Album.find_by_sql('SELECT * FROM albums
WHERE release_date <= \'2006-11-10\'AND artist LIKE \'%Tupac%\'
ORDER BY release_date ASC ;')
end
def alt_album_list
release_date = '2006-11-10'
artist = ''
@albums = Album.find(:all,
:conditions => ["release_date <= ? AND artist LIKE ?",release_date,
'%' + artist +'%'],
:order => 'title ASC',
:limit => 25)
render(:action => 'album_list')
end
def show_album
release_date = '2006-11-10'
artist = 'Tupac'
@album = Album.find(:first,
:conditions => ["release_date <= ? AND artist LIKE ?",release_date,
'%' + artist +'%'],
:order => 'title ASC')
end
def list
@albums = Album.find(:all)
render(:action => 'album_list')
end
def show
@album = Album.find(params['id'])
render(:action => 'show_album')
end
def new
@album = Album.new
end
def create
@album = Album.new(params[:album])
if @album.save
redirect_to(:action =>'list')
else
render(:action => 'new')
end
end
def edit
@album = Album.find(params[:id])
end
def update
@album = Album.find(params[:id])
if @album.update_attributes(params[:album])
redirect_to(:action =>'list')
else
render(:action => 'new')
end
def destroy
@album = Album.find(params['id'])
@album.destroy
redirect_to(:action =>'list')
end
end
end
Do you have any ideas on why this is?
Thanks
Keith
