Question

Are after_create and after_save the same as per functionality?

I want to do an operation with the email of a user after its account creatio

Answer 1

after_save()

Works fine when you have to save models that do not save very often. For this particular example of changing records frequently it would be advisable to use

 after_commit()

make sure that the model is saved in the database before the action is executed after_commit :calculate_credit_score

def calculate_credit_score
     #Call a Cron job
end
