validates_inclusion_of(*attr_names)
public
Validates whether the value of the specified attribute is available in a particular enumerable object.
class Person < ActiveRecord::Base validates_inclusion_of :gender, :in=>%w( m f ), :message=>"woah! what are you then!??!!" validates_inclusion_of :age, :in=>0..99 end
Configuration options:
- in - An enumerable object of available items
- message - Specifies a customer error message (default is: "is not included in the list")
- allow_nil - If set to true, skips this validation if the attribute is null (default is: false)
- if - Specifies a method, proc or string to call to determine if the validation should
occur (e.g. :if => :allow_validation, or :if => Proc.new { |user| user.signup_step > 2 }). The method, proc or string should return or evaluate to a true or false value.
