Availables validators: AssociationLength, Email, Existence, Slug, Url, Money

class User < ActiveRecord::Base
  validates :email, :email => true
  validates :site, :url => true, :allow_blank => true
  validates :inn, :inn => true   
end

class Company < ActiveRecord::Base
  # note AssociationLengthValidator is inherited from ActiveModel::Validations::LengthValidator
  # http://api.rubyonrails.org/classes/ActiveModel/Validations/LengthValidator.html
  # so you can easily use standard options like :is, :minimum, :maximum, etc.

  validates :employees,
    :association_length => {
      :minimum => 1,
      :select => ->(employee) { employee.name.in? ["Mike", "John"] }
    }

  validates :employees, :association_length => { :minimum => 1, :select => :employees_filter }

  def employees_filter(employees)
    employees.select { |employee| employee.name.in? ["Mike", "John"] }
  end
end

class Page < ActiveRecord::Base
  validates :slug, :slug => true
end
