Can't find the the 'destroy' action, but it's there... weird error

My app can't seem to find the 'destroy' action in my Sessions controller. Weird, because it's 开发者_JS百科there.

I have a link like so:

<%= link_to "Logout", logout_path %>

Which I route to my destroy action in routes.rb:

match '/logout' => "sessions#destroy", :as => "logout"

And here is the 'destroy' action in my sessions controller:

def destroy
  reset_session
  redirect_to videos_path
end

When I click the link, I get this error in my logs:

Started GET "/logout" for 127.0.0.1 at Thu Mar 24 02:58:36 -0700 2011

AbstractController::ActionNotFound (The action 'destroy' could not be found for SessionsController):

What's going on here?

UPDATE:

Here's my routes.rb file:

root :to => "videos#new"
resources :videos
resources :video_votes
resources :users
resource :session
match '/login' => "sessions#new", :as => "login"
match '/logout' => "sessions#destroy", :as => "logout"

Here's my entire Sessions controller:

class SessionsController < ApplicationController

  def create
    if user = User.authenticate(params[:email], params[:password])
      session[:user_id] = user.id
      redirect_to videos_path
    else
      flash.now[:alert] = "Invalid login/password combination"
      render :action => 'new'
    end

    def destroy
      reset_session
      redirect_to videos_path
    end
  end
end

---

It looks like I messed up the placement of end in my Sessions controller that was causing my destroy method to not work...

I had to change my Sessions controller to:

class SessionsController < ApplicationController

def create
  if user = User.authenticate(params[:email], params[:password])
    session[:user_id] = user.id
    redirect_to videos_path
  else
    flash.now[:alert] = "Invalid login/password combination"
    render :action => 'new'
  end
end

  def destroy
    reset_session
    redirect_to videos_path
  end
end

Try to change this line :

match '/logout' => "sessions#destroy", :as => "logout"

and make it look like this one :

get '/logout' => "sessions#destroy", :as => "logout"

it's the same route but it will respond only to get request for this specific action.

---

Ok I think I got it

Change routes.rb to

resources :sessions
