Can't patchEntity assocciated entity

I have a Register page that allow parents to register their child to courses.

The page contents:

  • Logging in data: new user data (Users table)
  • Parents data: The 2 parents (Parents table)
  • Pupil data: The registering child (Pupils table), only some data of the kid in here, other data in Kids table
  • Siblings data: other kids of the same parents (Kids table), the pupil also in this list.
  • Course ID : the course that Pupil enroll to (Courses table)
  • Education histories: of the pupil (EduHistories table)

Please advice me the better approach for this.

  • Should I patch and save them all in UsersController->register() action?
  • If splitting into many actions for each controller, how can I make them work together as 1 registering page for user GUI ?

Thank you very much for your advice.
