How do you reconcile foreign keys for forms?

Hi all,

I'm looking to resolve foreign keys for forms -- similar to the way "streamlined" does it. Although the actual value stored in an object is the foreign key integer, I'd like the actual name of the item displayed.

I'm *sure* it's easy. Thoughts?

Regards.

So you have one object, say a user and another one that belongs to the user, say an address

then: User model:

has_one :address

Address model

belongs_to :user

then after finding the user @user = User.find(params[:id])

you can access the address with @user.address or single address fields @user.address.city

belongs_to and has_many have a lot of options. You can set a foreign_key if you don't use the default user_id in the address table
