Hi All,
I am facing sort of problem while validating .
Two models User & Product.
class User < ActiveRecord::Base
has_many :products, :dependent => :destroy
end
class Product < ActiveRecord::Base
belongs_to :user
validates :itemcode, :uniqueness => true
end
Now case,
System has number of users who can insert product information with
itemcode
uniqueness, but we need uniqueness validation with user_id and
itemcode.System need to check join table validation for new item with
user_id and itemcode.
Please suggest.
Thanks.
