redirect_to and :controller, :actions getting mixed up in Rails

In a Rails controller I'm calling this:

redirect_to :controller => "user", :action => "login" 

My 开发者_Go百科user_controller.rb defines the following method:

class UserController < ApplicationController
  def login
  ###
  end

When I call my redirect_to method I get this error in my browser: No action responded to show. Checking the server logs I see this line:

Processing UserController#show (for 127.0.0.1 at 2009-12-19 12:11:53) [GET] 
  Parameters: {"action"=>"show", "id"=>"login", "controller"=>"user"} 

Finally, I've got this line in my routes.rb

map.resources :user

Any idea what I'm doing wrong?

The hack-y answer is to change the following line in your routes.rb

map.resources :user

to

map.resources :user, :collection => { :login => :get }

But that's bad for a variety of reasons -- mainly because it breaks the RESTful paradigm. Instead, you should use a SessionController and use sessions/new to login. You can alias it to /login by the following line in routes.rb

map.login 'login', :controller=>"sessions", :action=>"new"

Tried

redirect_to :url => {:action => 'login', :controller => 'user'}

Or you might have to remove the routing or write your own. The routing maps POST to create, PUT to update etc.

You need to add the login action in your routes.rb. Refer to this excellent guide.

What I ended up doing was creating a new login_controller to handle logins.

Here's the relavent bit from my routes.rb file:

map.login '/login', :controller => 'login', :action => 'login'

Thanks for your help...
