hi guys,
I been trying to find out on how to validate the presence of foreign
keys/associated objects and the threads that talk about this are
rather dated and unanswered. I looked at
http://groups.google.com/group/rubyonrails-talk/browse_thread/thread/f8175db2a8321750/d565496a3672f19f?lnk=gst&q=validates+presence+foreign#d565496a3672f19f

Consider this:
class Part < ActiveRecord::Base
belongs_to :brand
belongs_to :category
belongs_to :sub_category
belongs_to :user
belongs_to :status
has_many :fits
has_many :images, :dependent => :destroy
validates_presence_of :title, :description, :category, :location,
:contact_name, :contact_number, :condition
end
class Brand < ActiveRecord::Base
has_many :designs
validates_presence_of :name
end
class Fit < ActiveRecord::Base
belongs_to :Part
belongs_to :Brand
validates_presence_of :part_id
end
When I hit the “submit” button to purposely try and create a new
“Fit” object without selected a Brand (the brand is a drop down box)
and the Part ID is a hidden field, no errors come up.
How do I validate the presence of the “Part ID” (or part object)
within the Fit model?
I tried putting " validates_presence_of :part_id" and it does not
work.
Any ideas, guys?
thanks
