How to add records to two tables?

Question

Ruby on Rails

Hello everyone) In general, the situation is this, there is a User and Student table. Student has a user_id. I want to make it so that when saving a record in User , the id of the just saved user appears in the user_id field in the Student table. Tried to do with callbacks, but something doesn't work. Has anyone implemented something similar? Share your experience. Thanks in advance)

Answer 1

Show me how you implemented it with callbacks.
Do you get

class User
  has_one/has_many :students 
end

Show callback'i please. Why the Student model, if it is needed only for the role?
