validates_enumeration_of(*args)
click to toggle source
Validates whether the value of the specified attribute is available in the given Protobuf
Enum. The enumeration should be passed as a class that defines the enumeration:
“` class User < ActiveRecord::Base
include ::Protoable validates_enumeration_of :role_type, :with => RoleType, :allow_nil => true
end “`
In this example, RoleType is a defined as a protobuf enum.
It accepts the same options as `validates_inclusion_of` (the :in option is automatically set and will be overwritten).
