Question

I have an action (send_confcode) that will send a confirmation code via sms as soon as a new user signs up. I would like to know where this action should be placed. Is it under the User model generated by Devise?

def send_confcode     
  @confcode = (Time.now.to_i).to_s.slice(6,9)
  # more code here for sending code via an sms api
end

Answer 1

Use an after_create callback method in your User model. Add this to your user model:

after_create :send_confcode

After a user is created it will call the send_confcode method.
