Routing Error with sign_out in devise in rails 3.0.9

I've gone through many other stack overflow posts (e.g. this one: No route matches "/users/sign_out" devise rails 3), but I've not found anything that works.

Here's my view:

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

But when I click on the sign_out link, the server doesn't seem to process the "delete." It still thinks I want to a GET request.

Started GET "/users/sign_out" for 127.0.0.1 at 2011-10-03 20:45:54 -0400

ActionController::RoutingError (No route matches "/users/sign_out"):

I've also including the javascript tag that the other SO threads have mentioned in my application.html.erb:

<%= javascript_include_tag :defaults %>
<script src="/javascripts/jquery.js"></script>
<sc开发者_如何学编程ript src="/javascripts/jquery.tools.min.js"></script>    
<%= render 'layouts/stylesheets'%>

Totally at a loss.

Try adding in gem 'jquery-rails' to your gem file, and run the generator as rails g jquery:install --ui to ensure that it installs JQueryUI as well as UJS. If it asks to overwrite any files just choose 'yes'.

Also change the above to <%= javascript_include_tag :all %>

Once this is done try it once more - good luck!
