The same purpose could be achieved with `MethodField()`, but it'll be just too annoying. Example: class Subscription: status = ("active", "trialing", "canceled") class SubscriptionSerializer(Serializer): status = ListField(CharField(label="allowed_status", required=True)) serialized_obj = SubscriptionSerializer(subscription).data # serialized_obj = {"allowed_status": ["active", "trialing", "canceled"]} :param field_instance: a Field instance that represents the type of a single element of the iterable to be passed to `to_value()` method. Note that the `field_instance` cannot be a `MethodField()`, a `ConstantField()` or a `Serializer` (which has the option `many=True` for the same purpose). The `ListField` generates a new field class (and instance) during the declaration (before the runtime), for perfomance purpose. zList{}r csi|]}|t|qSr)getattr).0namerrr iszListField..csfdd|DS)Ncsg|]}|qSr)r)r"vrrr lsz/ListField..to_value..r)valuerrrrkszListField..to_valueNr) r rtyperrr __slots__r r)r field_classListFieldClassattrsrrrr ListFieldKs   r-c@s2eZdZdZdZd ddZddZed d ZdS) ConstantFielda= A Field that allows to constant data injection into the serialized object, without the need to declare an (serialized) object method, or a serializer's `MethodField()` to return a constant.
