belongs_to, has_many relationship using other foreign key

rubyonrails-talk
1

I am creating a relationship between two tables and objects.

public_user has_many :orders

orders

belongs_to :public_user

however I need to connect them using a foreign key other than the public_user_id. Namely the customer_number field.

How do I code this in Ruby on Rails?

Thank you for your time in advance.

Look into the :foreign_key option to has_many/belongs_to. It allows you to change the field used to join on.
