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

I know this is an old question based on Rails 3 but I just ran into and solved it on Rails 4.0.4. So thought I'd pitch in how I fixed it for anyone encountering this problem with this version. Your mileage may vary but here's what worked for me.

First make sure you have the gems installed and run bundle install.

gem 'jquery-rails'

gem 'turbolinks'

gem 'jquery-turbolinks'

In application.js check that everything is required like below.

Beware if this gotcha: it's //= require jquery.turbolinks and not //= require jquery-turbolinks

//= require jquery
//= require jquery_ujs
//= require jquery.turbolinks
//= require turbolinks
//= require_tree .

Next, add the appropriate links in the header of application.html.erb.

<%= javascript_include_tag  "application", "data-turbolinks-track" => true %>
<%= javascript_include_tag :defaults %>

There seems to be many variations on how to implement the delete method which I assume depends on the version of Rails you are using. This is the delete syntax I used.

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

Hope that helps dig someone out of this very frustrating hole!

I think the route for signing out is a DELETE method. This means that your sign out link needs to look like this:

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

Yours doesn't include the :method => :delete part. Also, please note that for this to work you must also include <%= javascript_include_tag :defaults %> in your layout file (application.html.erb).

Answer 3

See if your routes.rb has a "resource :users" before a "devise_for :users" then try swapping them:

1. Works

   • devise_for :users
   • resources :users

2. Fails

   • resources :users
   • devise_for :users

Answer 4

Other option is to configure the logout to be a GET instead a DELETE, you can do that adding the following line on /config/initializers/devise.rb

config.sign_out_via = :get

But as Steve Klabnik wrote on his blog (http://blog.steveklabnik.com/2011/12/11/devise-actioncontroller-routingerror-no-route-matches-get-slash-users-slash-sign-out.html) try to use DELETE because of the semantic of this method.

Answer 5

This means you haven't generated the jquery files after you have installed the jquery-rails gem. So first you need to generate it.

rails generate devise:install

First Option:

This means either you have to change the following line on /config/initializers/devise.rb

config.sign_out_via = :delete to config.sign_out_via = :get

Second Option:

You only change this line <%= link_to "Sign out", destroy_user_session_path %> to <%= link_to "Sign out", destroy_user_session_path, :method => :delete %> on the view file.

Usually :method => :delete is not written by default.

Answer 6

use :get and :delete method for your path:

devise_scope :user do
  match '/users/sign_out' => 'devise/sessions#destroy', :as => :destroy_user_session, via: [:get, :delete]
end
