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

Check it out with source code in github:

https://github.com/plataformatec/devise/commit/adb127bb3e3b334cba903db2c21710e8c41c2b40#lib/generators/templates/devise.rb (date : June 27, 2011 )

• # The default HTTP method used to sign out a resource. Default is :get. 188
• # config.sign_out_via = :get 187
• # The default HTTP method used to sign out a resource. Default is :delete. 188
• config.sign_out_via = :delete

  devise_for :users
  devise_scope :user do
    get '/users/sign_out' => 'devise/sessions#destroy'
  end

Answer 3

The ability to make the Logout link a DELETE RESTful call requires an html attribute data-method = "delete" by using the rails code = link_to('Logout', destroy_user_session_path, :method => :delete).

However, if you do not have the gem jquery-ujs installed or are not calling the resulting javascript in your application.html via = javascript_include_tag "application", the response will be sent as a GET request, and the route will fail.

You have a few options if you do not want to use jquery-ujs or cannot find a way to make it work:

1. Change config.sign_out_via to equal :get within devise.rb (not recommended, since DELETE is the appropriate RESTful query)
2. OR Change the link_to to = button_to('Logout', destroy_user_session_path, :method => :delete). With button_to Rails will do the heavy lifting on making the proper DELETE call. You can then style the button to look like a link if you wish.

Answer 4

Add:

  <%= csrf_meta_tag %>  and 
  <%= javascript_include_tag :defaults %>  to layouts

Use these link_to tags

 link_to 'Sign out', destroy_user_session_path, :method => :delete

  or

 link_to 'Sign out', '/users/sign_out', :method => :delete

In routes add:

  devise_for :users do
    get '/users/sign_out' => 'devise/sessions#destroy'
  end

Answer 5

I want to add to this even though it's a bit old.

the "sign_out" link didn't work, despite having :method => :delete.

The comment indicating that <%= javascript_include_tag :defaults %> must be included reminded me I had recently added JQuery java script and used simple <script src=""/> tags to include them.

When I moved them from after the :defaults to before, the sign_out started working again.

Hopefully this helps someone.

Answer 6

Lots of solutions are there. but mostly use this,

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

or config devise.rb with proper sign_out method

In devise.rb

config.sign_out_via = :delete ( or  :get which u like to use.)
