This model has some errors that I wasn't able to get sorted out the two lines that begin with validate should be validates but after that I don't understand what the author's trying to do If I change them to validates I get the error Unknown validator: 'MessageValidator' for validate :auction_active?, message: :auction_active
class Bid < ActiveRecord::Base
belongs_to :auction
belongs_to :user
validates :auction, :user, presence: true
validate :auction_active?, message: :auction_active
validate :last_user_different?
scope :sorted, -> { order(:created_at) }
after_create :update_auction
private
def auction_active?
if auction && !auction.active?
if auction.finished?
errors.add(:auction, :finished)
else
errors.add(:auction, :not_started)
end
end
end
def last_user_different?
if auction && user
errors.add(:user, :same_user_twice) if auction.last_user == user
end
end
def update_auction
auction.increase_price_and_time
auction.publish_updates
end
end
