belongs_to and multiple foreign keys
Hi all,
I''m confused about how I''m supposed to specify a belongs_to relationship when
the table includes multiple columns that reference the same parent table.
In my case I have a "schedules" table with "opened_by" and "closed_by" columns,
that both reference the "users" table. In theory, they can be two different
user ids.
