How to add callback after registration with Rails3 and Devise

问题

How to add a callback to create an account for the registered user.

Devise files (registrations_controller.rb) are under controllers/devise My user model has has_many :accounts relationship (and the account model has belongs_to :user)

First I don't know where to add the callback (what file?)

Then, how to automatically create a new account with the right user_id of the registered user?

Thanks in advance.

回答1:

You can override devise's registration controller, add callback to create account using filters. Remember to name the file registrations_controller.rb

class RegistrationsController < Devise::RegistrationsController
  after_filter :add_account 

  protected

  def add_account
    if resource.persisted? # user is created successfuly
      resource.accounts.create(attributes_for_account)
    end
 end
end

then in your routes.rb tell devise to use overrided controller for registration

devise_for :users, controllers: { registrations: 'registrations'}

Here's a thread on the google group that answers your question:

http://groups.google.com/group/plataformatec-devise/browse_thread/thread/6fc2df8d71f8b2f0

Basically it recommends just adding a standard rails "after_create" method to your user model to run the code you need.

回答3:

I'm using both approaches.

after_create in the model to create associated data and after_filter :send_notification_mailer, only: :create In the RegistrationsController (same as @naveed)

because in the after_create callback I was receiving the error exception ActiveJob::DeserializationError: Couldn't find User with id

when sending with Active Job the confirmation email in background with sidekiq because the user it was not persisted sometimes.

First, open your version of devise with bundle open devise. Check out the app/controllers/devise/registrations_controller.rb. You will probably see a method called in the create method when a user successfully registers. For my version (3.5.2) it is sign_up.

In routes, you'll need

devise_for :users, :controllers => { :registrations => "registrations" }

The you can define your own RegistrationsController like so:

class RegistrationsController < Devise::RegistrationsController    
  protected

  def sign_up(_resource_name, user)
    super
    # do your stuff here
  end
end
