ruby on rails - What is the difference between `after_create` and `after_save` and when to use which?

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 creation.

I want to do that operation when it is saved in the database.

which is preferable to use: after_create or after_save?

Answer 1

after_create only works once - just after the record is first created.

after_save works every time you save the object - even if you're just updating it many years later

So if you want to do this email operation only just the once (and then never again) then use after_create.

If you want to do it every time the object is saved, then do it in after_save
