Scoped uniqueness validation of associated objects
Reported by Andriy Tyurnikov | April 5th, 2011 @ 11:41 AM
class Poll < ActiveRecord::Base
has_many :answers
validates_associated :answers
accepts_nested_attributes_for :answers, :allow_destroy => true end
class Answer < ActiveRecord::Base
belongs_to :poll
validates_uniqueness_of :body, :scope => :poll_id end
When new poll is created,
attributes for associated answers are passed,
but uniqueness of answers body in scope of poll is not
validated.
Any ideas how to fix that.
