Rails correct way to use link_to with devise

I'm getting started with rails and devise for authentication and I want to make a link to sign out when a user is logged into the admin page.

What is the correct way to write the link_to code

Here's my rake routes:

admin_index        /admin/index(.:format)         {:controller=>"admin/home", :action=>"index"}
        new_user_session GET    /users/sign_in(.:format)       {:action=>"new", :controller=>"devise/sessions"}
            user_session POST   /users/sign_in(.:format)       {:action=>"create", :controller=>"devise/sessions"}
    destroy_user_session DELETE /users/sign_out(.:format)      {:action=>"destroy", :controller=>"devise/sessions"}
           user_password POST   /users/password(.:format)      {:action=>"create", :controller=>"devise/passwords"}
       new_user_password GET    /users/password/new(.:format)  {:action=>"new", :controller=>"devise/passwords"}
      edit_user_password GET    /users/password/edit(.:format) {:action=>"edit", :controller=>"devise/passwords"}
                         PUT    /users/password(.:format)      {:action=>"update", :controller=>"devise/passwords"}
cancel_user_registration GET    /users/cancel(.:format)        {:action=>"cancel", :controller=>"devise/registrations"}
       user_registration POST   /users(.:format)               {:action=>"create", :controller=>"devise/registrations"}
   new_user_registration GET    /users/sign_up(.:format)       {:action=>"new", :controller=>"devise/registrations"}
  edit_user_registration GET    /users/edit(.:format)          {:action=>"edit", :controller=>"devise/registrations"}
                         PUT    /users(.:format)               {:action=>"update", :controller=>"devise/registrations"}
                         DELETE /users(.:format)               {:action=>"destroy", :controller=>"devise/registrations"}
              home_index GET    /home/index(.:format)          {:controller=>"home", :action=>"index"}
                    root        /                              {:controller=>"home", :action=>"index"}

I tried <%= link_to "Sign Out", destroy_user_session_path %> but when i click the link it gives me the error:

No route matches [GET] "/users/sign_out"

From this devise sample application, recommended on the Devise wiki:

<% if user_signed_in? %>
  <li><%= link_to 'Edit account', edit_user_registration_path %></li>
  <li><%= link_to 'Sign out', destroy_user_session_path, :method=>'delete' %></li>
<% end %>

the root error of your problem is that you haven't use RESTful routes in your "link_to".

you should correct your code to: 

<%= link_to "Sign Out", destroy_user_session_path, :method => :delete %>

so that it will match the routes

DELETE /users(.:format)  {:action=>"destroy", :controller=>"devise/registrations" }
