On destroying session via Devise “Couldn't find User with 'id'=sign_out”

Question

I\'m running Rails 5.1.2 and Ruby 2.4.0.

I\'ve created a method in the ApplicationController called require_login that checks if the user is logged in order

You've done everything right. The only missing thing is the :method => :delete call. This is rails specific and you need rails-ujs or for older rails version jquery_ujs to make it work.

Add this to your app/assets/javascripts/application.js:

# for rails 5.1 or higher
//= require rails-ujs

# for rails 5.0 or lower
//= require jquery
//= require jquery_ujs

If you don't add this, the method: :delete call will not work. If you don't want to use it at all, then change sign_out to work with GET.

Change or add this to your config/initializers/devise.rb:

config.sign_out_via = :get

If it's still not working, then you have the wrong order in your config/routes.rb file. devise_for :users must be before resources :users:

devise_for :users
resources :users
