Method: Devise::Controllers::Helpers#sign_in

Defined in:
lib/devise/controllers/helpers.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. The only exception is the :bypass option, which bypass warden callbacks and stores the user straight in session. This option is useful in cases the user is already signed in, but we want to refresh the credentials in session.

Examples:

 :user, @user                      # sign_in(scope, resource)
 @user                             # sign_in(resource)
 @user, :event => :authentication  # sign_in(resource, options)
 @user, :bypass => true            # sign_in(resource, options)
