Validating Foreign Key
Howdy,
I''m a Rails beginner working on my first significant project with RoR.
I''m trying to figure out how to validate a foreign key (you know, make
sure the row actually exists.)
However, validates_associated doesn''t seem to be what I want to use, nor
does it work...

Foreign key confusion
I have 2 models right now: "users" and "posts". When a user creates a
post I would like their id to be recorded under "user_id" in the "posts"
table. Under the "user" model I have:
class User < ActiveRecord::Base
has_many :posts

And under the "posts" model I have:

belongs_to and multiple foreign keys
Hi all,
I''m confused about how I''m supposed to specify a belongs_to relationship when
the table includes multiple columns that reference the same parent table.
In my case I have a "schedules" table with "opened_by" and "closed_by" columns,
that both reference the "users" table. In theory, they can be two different
user ids.
