Compare with:

validates_acceptance_of(*attr_names)

Encapsulates the pattern of wanting to validate the acceptance of a terms of service check box (or similar agreement).

class Person < ActiveRecord::Base
  validates_acceptance_of :terms_of_service
  validates_acceptance_of :eula, message: 'must be abided'
end

If the database column does not exist, the terms_of_service attribute is entirely virtual. This check is performed only if terms_of_service is not nil and by default on save.

Configuration options:

:message - A custom error message (default is: “must be accepted”).
:accept - Specifies a value that is considered accepted. Also accepts an array of possible values. The default value is an array [“1”, true], which makes it easy to relate to an HTML checkbox. This should be set to, or include, true if you are validating a database column, since the attribute is typecast from “1” to true before validation.

There is also a list of default options supported by every validator: :if, :unless, :on, :allow_nil, :allow_blank, and :strict. See ActiveModel::Validations#validates for more information.
