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
