[ruby-on-rails] No route matches "/users/sign_out" devise rails 3

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?

The problem begin with rails 3.1... in /app/assets/javascript/ just look for application.js.

If the file doesn't exist create a file with that name I don't know why my file disappear or never was created on "rails new app"....

That file is the instance for jquery....

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 If you do, you're probably out-of-date.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.

If you're using HTTPS with devise, it'll break if your sign-out link is to the non-secure version. On the back end, it redirects to the secure version. That redirect is a GET, which causes the issue.

Make sure your link uses HTTPS. You can force it with protocol: "https" in your url helper (make sure you use the url helper and not the path helper).

<%= link_to "Sign out", destroy_user_session_url(protocol: "https"), method: :delete %>

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

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

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.) 

I had the same problem with rails 3.1.0, and I solved adding in file the followings lines:

app/assets/javascripts/application.js
//= require_tree
//= require jquery
//= require jquery_ujs

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!

Don't forget to include the following line in your application.js (Rails 3)

//= require_self
//= require jquery
//= require jquery_ujs

Include jquery_ujs into my rails application and it works now.

Many answers to the question already. For me the problem was two fold:

1. when I expand my routes:

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

2. I was getting warning that this is depreciated so I have replaced it with:

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

3. I thought I will remove my jQuery. Bad choice. Devise is using jQuery to "fake" DELETE request and send it as GET. Therefore you need to:

   //= require jquery
   //= require jquery_ujs
   

4. and of course same link as many mentioned before:

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

In general when you get "No route matches" but you think you have that route defined then double check the http verb / request method (whether its get, put, post, delete etc.) for that route.

If you run rake routes then you will see the expected method and you can compare this with the request log.

This is what I did (with Rails 3.0 and Devise 1.4.2):

1. Make sure your page loads rails.js
2. Use this param: 'data-method' => 'delete'
3. Good idea to add this param: :rel => 'nofollow'

Try adding a new route to devise/sessions#destroy and linking to that. Eg:

routes.rb
devise_for :users do
  get 'logout' => 'devise/sessions#destroy'
end

view:

<%= link_to "Logout", logout_path %>

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

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.

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

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

Most answers are partial. I have hit this issue many times. Two things need to be addressed:

<%= link_to(t('logout'), destroy_user_session_path, :method => :delete) %>

the delete method needs to be specified

Then devise uses jquery, so you need to load those

   <%= javascript_include_tag "myDirectiveJSfile" %> 

and ensure that BOTH jquery and jquery-ujs are specified in your myDirectiveJSfile.js

//= require jquery
//= require jquery_ujs

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' %>

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

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

If you are using Rails 3.1 make sure your application.html.erb sign out looks like:

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

And that your javascript include line looks like the following

<%= javascript_include_tag 'application' %>

My guess is that some gems overwrite the new structure of the default.js location.

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 %>

Use it in your routes.rb file:

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

I changed this line in devise.rb:

config.sign_out_via = :delete

to

config.sign_out_via = :get

and it started working for me.

the ':method => :delete' in page is 'data-method="delete"' so your page must have jquery_ujs.js, it will submit link with method delete not method get

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.

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.

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.
