HABTM using two columns
Hi all,
I was wondering whether anyone could guide me to docu and code
examples how to create and use a has_and_belongs_to_many relationship
with a joining table where TWO columns are used to identify the
relation to TWO alternative tables.
Example:
table 1: mothers [mother_id, name]
table 2: fathers [father_id, name]
table 3: children [child_id, name]
joining table 4: children_parent
