No route matches “/users/sign_out” devise rails 3

Question

I've installed devise on my app and applied the following in my application.html.erb file:

<div id="user_nav">
    <% if user_signed_in? %>
        Signed in as <%= current_user.email %>. This cannot be cheese?
        <%= link_to 'Sign out', destroy_user_session_path %>
    <% else %>
        <%= link_to 'Register', new_user_registration_path %> or <%= link_to 'Sign in', new_user_session_path %>
    <% end %>
</div>

I ran rake routes and confirmed that all the routes are valid.

Also, in my routes.rb file I have devise_for :users and root :to => "home#index".

I get the following routing error when clicking the "Sign out" link:

No route matches "/users/sign_out"

Any ideas what's causing the error?

Answer 1

You probably didn't include jquery_ujs javascript file. Make sure you are using the latest version of jquery-ujs : https://github.com/rails/jquery-ujs and the last files available :

rails generate jquery:install

You should not have any more rails.js file. If you do, you're probably out-of-date. Make sure also this file is loaded with defaults, in config/application.rb

config.action_view.javascript_expansions[:defaults] = %w(jquery.min jquery_ujs)

(Again, you should not have rails.js file here). Finally, add the link as documented on Devise wiki (haml-style):

= link_to('Logout', destroy_user_session_path, :method => 'delete')

And everything will be fine.

Answer 2

In your routes.rb :

 devise_for :users do
    get '/sign_out' => 'devise/sessions#destroy'
    get '/log_in' => 'devise/sessions#new'
    get '/log_out' => 'devise/sessions#destroy'
    get '/sign_up' => 'devise/registrations#new'
    get '/edit_profile' => 'devise/registrations#edit'
 end

and in your application.html.erb:

<%if user_signed_in?%>
          <li><%= link_to "Sign_out", sign_out_path %></li>
<% end %>

Answer 3

With one exception, Jessie's answer worked for me:

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

change:

:delete

... to:

'delete'

So the code that worked for me is:

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

Answer 4

I changed this line in devise.rb:

config.sign_out_via = :delete

to

config.sign_out_via = :get

and it started working for me.

Answer 5

Well, guys for me it was only remove the :method => :delete

<%= link_to('Sign out', destroy_user_session_path) %>
