Unable to sign out in a Rails app, using Devise gem, no route matches /users/sign_out

I know there are dozens of questions on different sites about this issue. I have tried a lot of things, and I still can't get the link with DELETE method to work.

I've created an empty rails application

Versions:

  • devise 2.0.4
  • rails: 3.2.2
  • Ruby: 1.9.2
  • RVM: 1.10.3

After I installed devise gem, I ran these commands:

rails generate devise:install
rails generate devise User

Fixes I have tried are below:

Initial link:

<%= link_to "Sign out", destroy_user_session_path %>

I added the delete method, in ticks and without them:

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

Added this to application.html.erb:

<%= javascript_include_tag :defaults %>

I uncommented these lines in assets/javascripts/application.js:

= require jquery
= require jquery_ujs

I also tried getting the GET link to work, changed this line from config/initializers/devise.rb

config.sign_out_via = : delete

to this:

config.sign_out_via = :get if Rails.env.test?

No matter what I try, DELETE links result in this:

No route matches [GET] "/users/sign_out"

GET links don't work as well:

No route matches [GET] "/"

I have tried restarting the server, of course.

Rake routes contains this:

 destroy_user_session DELETE /users/sign_out(.:format)      devise/sessions#destroy

Thanks in advance.

in devise.rb

find config.sign_out_via = :delete

change to config.sign_out_via = :get

if you use :get make sure you are using :method = :get and if you are using :delete using :method => :delete in your link

in production you may have to swap it round, so you should use an if statement to check RAILS_ENV

In your example you are probably running in development mode and not test, which is why it's probably not working.

And restart your server as it's an initialiser.

This helper always works for me:

link_to "Logout", destroy_user_session_path, :method => :delete

Maybe you are not logged in properly? You could check with if current_user

Can we see your routes file?

Specifically the devise_for call

You could also try setting the path explicitly

devise_for :users, path_names: { sign_out: 'sign_out' }
