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
class Part < ActiveRecord::Base
has_many :images, :dependent => :destroy
validates_presence_of :title, :description, :category, :location, :contact_name, :contact_number, :condition
class Brand < ActiveRecord::Base
class Fit < ActiveRecord::Base
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
Any ideas, guys?
