Method: Devise::Controllers::SignInOut#sign_in

Defined in:
lib/devise/controllers/sign_in_out.rb

#sign_in(resource_or_scope, *args) ⇒ Object

Sign in a user that already was authenticated. This helper is useful for logging users in after sign up. All options given to sign_in is passed forward to the set_user method in warden. If you are using a custom warden strategy and the timeoutable module, you have to set `env = true` in the request to use this method, like we do in the sessions controller: github.com/plataformatec/devise/blob/master/app/controllers/devise/sessions_controller.rb#L7

Examples:

 :user, @user                      # sign_in(scope, resource)
 @user                             # sign_in(resource)
 @user, event: :authentication     # sign_in(resource, options)
 @user, store: false               # sign_in(resource, options)
