Question

Like the title says, I’m looking for the options for devises automatic class authenticate_user!, specifically, I want it to redirect_to to ‘/’ and not ‘/users/sign_in’

Answer 1

Do the following:

In config/initializers/devise.rb:

  config.warden do |manager| 
    manager.failure_app = CustomAuthenticationFailure 
  end

Create a new file called lib/custom_authentication_failure.rb:

  class CustomAuthenticationFailure < Devise::FailureApp 
  protected 
    def redirect_url 
      root_path  #or whatever route in your app that points to '/' 
    end 
  end 

And this to your config/application.rb:

  config.autoload_paths += %W(#{config.root}/lib)
