Rails app cannot find 'destroy_user_session_path' in javascript

I have a rails app that has been migrated over the years starting at 2.2 to 3.2. I am using Devise, and Omniauth to get logins working, unfortunately I think during migration I have messed something up.

When I try to setup the session delete in application.html.erb I get the following error:

undefined local variable or method `destroy_user_session_path' for #<#<Class:0xb468e278>:0xb423e1dc>

application.html.erb:

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
  <meta http-equiv="content-type" content="text/html;charset=UTF-8" />
  <title>Coffee Tracker</title>
  <%= stylesheet_link_tag 'application'%>
  <!--%= stylesheet_link_tag 'scaffold' %-->
</head>
<!--%= javascript_include_tag :defaults %-->
<%= javascript_include_tag 'application' %>
<%= csrf_meta_tag %>
...snip...
<% if user_signed_in? %>
  <span id="currentuser"><%= current_user.email %></span>
  <%= link_to('Logout', destroy_user_session_path, :method => 'delete') %>
<% else %>

I also get the same error when I try the line:

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

application.js

// Place your application-specific JavaScript functions and classes here

                           /:controller(/:action(/:id(.:format))) :controller#:action
Solution

  • I was missing the the database authenticatable devise module which adds the route.

    app/models/user.rb:

     devise :omniauthable, :database_authenticatable

    rake routes:

          new_user_session GET    /users/sign_in(.:format)               devise/sessions#new
          user_session POST   /users/sign_in(.:format)               devise/sessions#create
  destroy_user_session DELETE /users/sign_out(.:format)              devise/sessions#destroy
user_omniauth_callback        /users/auth/:action/callback(.:format) users/omniauth_callbacks#(?-mix:facebook)
           coffee_list GET    /coffee/list(.:format)                 coffee#list
                  root        /                                      menu#index
                              /:controller(/:action(/:id(.:format))) :controller#:action

    I found documentation to confirm that shows the modules that use authenticatable create these routes in the devise_for documentation: http://rubydoc.info/github/plataformatec/devise/master/ActionDispatch/Routing/Mapper#devise_for-instance_method
