Q:

Rails- devise not working http://localhost:3000/users/sign_out

I've looked through all of the post on this problem, but none of the solutions seem to work for me. I hope I'm not missing something obvious, but I'm new to rails and nothing is working. 
I get this error when trying to sign out with devise
No route matches [GET] "/users/sign_out"

Here's my header
<%= stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track' => true %>
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
<%= csrf_meta_tags %>

This is the line that's giving me problems, but all my other lines work fine
<li><%= link_to 'Sign out', destroy_user_session_path, :method => :delete %></li>

And my application.js looks good
//= require jquery
//= require jquery_ujs
//= require turbolinks

Devise is setup to logout via
config.sign_out_via = :delete

rake routes gives me

            new_link GET    /links/new(.:format)           links#new
           edit_link GET    /links/:id/edit(.:format)      links#edit
                link GET    /links/:id(.:format)           links#show
                     PATCH  /links/:id(.:format)           links#update
                     PUT    /links/:id(.:format)           links#update
                     DELETE /links/:id(.:format)           links#destroy
                root GET    /                              links#index

I'm not sure where the problem lies and don't know what else to try.

A:

Try adjusting devise.rb to the following:
config.sign_out_via = :get

You will need to restart your rails server for the configuration to apply properly.
