Question

routes.rb =>

Error =>

Routing Error

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

What should i do ?

Answer 1

You are calling the route using GET while the route requires DELETE, according to its definition.

destroy_user_session DELETE /users/sign_out(.:format)      {:action=>"destroy", :controller=>"devise/sessions"}

The link correctly uses DELETE

<%= link_to('Logout', destroy_user_session_path, :method => 'delete') %>

Did you try to visit the URL directly in your browser? In this case, it won't work. You need to click on a link with the DELETE method.

Answer 2

You Can try something like this This code below should works

my best regards

devise_for :users, :skip => [:sessions]
as :user do
    get 'signin' => 'devise/sessions#new', :as => :new_user_session
    post 'signin' => 'devise/sessions#create', :as => :user_session
    get 'signout' => 'devise/sessions#destroy', :as => :destroy_user_session
end
