It''s absolutely necessary to use foreign key constraints -- has_many
and
things like that aren''t really constraints, and anyway, they only come
into play if the DB is modified through the ActiveRecord interface.  To
keep your data safe, you *must* use foreign key constraints.  Use the
Foreigner plugin to manage these constraints easily from migrations.

Search the list archives for more info.
