Custom REST action does not work?

tasks_controller.rb
 
class TasksController < ApplicationController
  
  def completed
    @tasks = Task.find(:all, :conditions => 'completed IS NOT NULL')
  end
  
  All other controller here ...
end
 
 
routes.rb
ActionController::Routing::Routes.draw do |map|
  map.resources :tasks, :collection => { :completed => :get }
 
   map.root :controller => "tasks"
 
  map.connect ':controller/:action/:id'
  map.connect ':controller/:action/:id.:format'
end
 
tasks/completed.rhtml.erb
<h1>Listing tasks</h1>
<% for task in @tasks %>

    <li><%=h task.name %> <%= link_to 'Show', task %> | <%= link_to 'Edit', edit_task_path(task) %> | <%= link_to 'Destroy', task, :confirm => 'Are you sure?', :method => :delete %></li>
  </ul>
<% end %>
