No match for route [GET] "/ logout"?

Rails.application.routes.draw do
  root to: 'users#index'
  get    '/login',   to: 'sessions#new'
  post   '/login',   to: 'sessions#create'
  delete '/logout',  to: 'sessions#destroy'
  resources :users
end

<% if logged_in? %>
    <li><%= link_to "Sign out", logout_path, method: :delete %>
<% end %>

GemFile

gem 'jquery-rails'
gem 'rails', '4.2.2'
gem 'turbolinks'


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

Is this a javascript issue? It doesn't seem to want to recognize the :: delete method?

Here is my application.html.erb file:

<!DOCTYPE html>
<html>
<head>
  <title>Workspace</title>
  <%= stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track' => true %>
  <%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
  <%= csrf_meta_tags %>
</head>
<body>

<%= yield %>

</body>
</html>

Is there an alternative way to pass the :: delete route method?

While submitting applications with broken javascript is not a good idea, it might make sense to secure some critical aspects of your application, such as logging out, using button_to

instead link_to

.

button_to "foo", bar method: delete

and link_to "foo", bar method: delete

both achieve the same goal - the request is sent as a POST request with a special parameter _method

used Rack::MethodOverride

to set the request method to PATCH, DELETE, etc.



button_to

creates an actual form containing hidden inputs and one button. link_to

uses javascript (Rails UJS) to create a virtual form and submits the form when the user clicks on the link.

One of two things happens:



  • The presented element <a>

    does not contain an attribute data-method

    to block UJS. Maybe there is an outdated version cached or you are looking at a different view? The easiest way to check is to go to your web inspector or view the source and confirm the existence of the attribute by clicking the corresponding link.

  • UJS does not handle clicking on an element. It might be due to a JS error, but it might be another click handler that you registered with priority. Check your JS console for errors to eliminate this as a potential cause, and if not, make sure the UJS script is in the sources panel:

    enter image description here

    If it is present and the behavior is the same, try adding a breakpoint in functions handleMethod

    in UJS and running again. If this happens, go to find out what is happening that is causing the crash. If it doesn't start, you can step back from there and look at other handlers by reference.

    [ breakpoint]

I don't quite understand why you think this is a javascript issue. I think you want something like the following:

<% if logged_in? %>
    <li>
        <%= link_to logout_path, method: :delete do %>
            <i class="fa fa-power-off"></i> Sign Out
        <% end %>
    </li>
<% end %>
