Validates that the specified attributes are blank (as defined by Object#present?).
class Person < ActiveRecord::Base validates_absence_of :first_name end
The first_name attribute must be in the object and it must be blank.
Configuration options:
-
:message - A custom error message (default is: “must be blank”).
There is also a list of default options supported by every validator: :if, :unless, :on, :allow_nil, :allow_blank, and :strict. See ActiveModel::Validations::ClassMethods#validates for more information.
