Question

I have a problem with a relationship that I dont how exactly to code. I been looking at the rails guide but no luck.

I have 3 Models: User, Owner and Company.

• User belongs_to Company / Company has_many Users

• Company belongs_to Owner / Owner has_one Company

The problem is the next: User and Owner are the same models, I now it is possible that two different classes use the same Model. But I don’t know how to do that. Could someone give me a hand with these? Thanks in advance.

Answer 1

You can define associations like this:

Company has_many users, dependent: :destroy
User belongs_to company
User has_one company

If your company table has column call owner_id, define this:

Company belongs_to owner, class_name: "User"

If your company table has column call user_id, define this:

Company belongs_to owner, class_name: "User", foreign_key: user_id
