Defined in:

Overview

Validates acceptance of obj’s attribute against a fixed value via :eql? call.

Unless the validation succeeds an error hash (:attribute => :message) is added to the obj’s instance of Errors.

Options:

:accept

object to check against (via :eql?)

:message

see NotNaughty::Errors for details

:if

see NotNaughty::Validation::Condition for details

:unless

see NotNaughty::Validation::Condition for details

Example:

invalid = 'abc'
valid = '1'
def invalid.errors() @errors ||= NotNauthy::Errors.new end
def valid.errors() @errors ||= NotNauthy::Errors.new end

AcceptanceValidation.new({}, :to_s).call invalid, :to_s, 'abc'
invalid.errors.on(:to_s).any? # => true

AcceptanceValidation.new({}, :to_s).call valid, :to_s, '1'
valid.errors.on(:to_s).any? # => false
