#Rails / has_one and has_many association both / without DB foreign ke

2020/01/13に公開

You can specify both

class User < ApplicationRecord
  has_one :book
  has_many :books
end

If use has one association and user has many books

user.book

then it maybe returns newest one "book" instance
but it does not return older other instances
