end

#validate_nested? ⇒ Boolean

The nested validator should be only added for those attributes that inherit from the AttributeObject::Model type. Otherwise this would be also added e.g. for ActiveRecord objects which would cause unexpected validation errors.

The hash type inherits from the array type, so this covers both cases.

Returns:

  • (Boolean)
