Hello,
I have a situation where an ''employee'' belongs to a
''department'' and
have setup the relationship as follows.
class Employee < ActiveRecord::Base
belongs_to :department, :foregin_key => "department_id"
validates_associated :department_id
end
class Department < ActiveRecord::Base
has_many :employees
def validate_on_update
unless self.find_by_id(id) error.add(:id, "is invalid department")
end
end
However when I try to save an employee with some test department
''578'',
get the following error because of validates_associated in employee
"undefined method `valid?'' for "578":String"
Any ideas what could be causing this?
Thanks
- Sree

You must provide a symbol referencing an association to the validates_associated macro: class Employee < ActiveRecord::Base belongs_to :department, :foregin_key => "department_id" validates_associated :department # not :department_id end Additional i don''t understand your validate_on_update code: You are testing if the specific object exists in the database only (on_update) if the object already exists in the database... -- Norman Timmler http://blog.inlet-media.de
Norman, Thanks a lot for the information. My update validation code was just stub to test. Thanks again. - Sree Norman Timmler wrote:> Am Montag, den 13.03.2006, 09:21 +0100 schrieb sreechand boppudi: >> has_many :employees >> "undefined method `valid?'' for "578":String" > You have an error in your Employee class.

I meant to say "validates_associated :department", or have the departmetn say something like "validates_associated :person" or whatever the object is called.
