I'm trying to make has_many relation with dynamic class_name attribute
class Category < ActiveRecord::Base
has_many :ads, :class_name => ( lambda { return self.item_type } )
end
or
class Category < ActiveRecord::Base
has_many :ads, :class_name => self.item_type
end
But i got errors:
can't convert Proc into String
or
undefined method `item_type' for #<Class:0xb62c6c88>
Thank you for any help!
