I have a join table:
When I add a relationship in the join table I then add data to the tb3
table and that populates the FK in tb3 with the id of the join table.
no problems there.
when I delete the row in the join table the data stays in the tb3
table. how do I get the tb3 data to delete?
Is not has_many supposed to delete the data on the other end when the
primary table no longer has a reference?
If I go into the DB and make the FK a constraint with a delete on
cascade it works when the data in the join table is deleted.
