Foreign Keys in ActiveRecord

Rails
1

Hello there,

I’m a beginner in Rails, so forgive me if this question is too dumb ;p
Does Rails provide any helper/linecode to create a foreign key in the
database (via migration)?

When I use, for example, belogs_to :class, :foreign_key => id_class,
I’m
just setting the name
of the foreign key.

In the same way, when I use *t.reference :class in the migration, *I’m
just creating an column *class_id *
with the appropriate class in the database… but I don’t properly
create
the foreign key in database-level,
right?

So, is there a nice way to do that in Rails? I already saw some
solutions
in the web, but I couldn’t find
any convention. Which would be the best way to do that?

Thanks in advance (:

P.S: sorry if the English is not good ;p

No - the official position has never been in favour of database level
constraints.
The foreigner gems adds migration helpers for adding foreign keys
