Overview

A mixin to handle specifying :if and :unless options to check before performing validation.

  validates_associated :tracks, :if => lambda { !validatable.tracks.empty? }
end

Validate if a given method on the validatable object returns true

setup_validations do
  validates_associated :tracks, :if => :allow_validation
end

def allow_validation
  false
end

Validate unless a given block returns true

setup_validations do
  validates_associated :tracks, :unless => lambda { validatable.tracks.empty? }
end

Validate unless a given method on the validatable object returns true

setup_validations do
  validates_associated :tracks, :unless => :disallow_validation
