Django Rest Framework 'serializers.DictFields' 不存在了吗?

Django Rest Framework does 'serializers.DictFields' no longer exist?

如果我从下方导入序列化程序并查找所有字段,我没有看到 DictField

>>> from rest_framework import serializers
>>> print("\n".join([foo for foo in dir(serializers) if "Field" in foo]))
BooleanField
BoundField
CharField
ChoiceField
DateField
DateTimeField
DecimalField
DjangoImageField
EmailField
Field
FieldDoesNotExist
FileField
FloatField
HiddenField
HyperlinkedIdentityField
HyperlinkedRelatedField
ImageField
IntegerField
ListField
ManyRelatedField
ModelField
MultipleChoiceField
NestedBoundField
NullBooleanField
PrimaryKeyRelatedField
ReadOnlyField
RegexField
RelatedField
SerializerMethodField
SkipField
SlugField
SlugRelatedField
StringRelatedField
TimeField
URLField

但它在文档 here 中,就在 ListField(在上面的列表中)之后。这在最新版本的 DRF 中消失了吗,还是我找错地方了?

DictField 已添加到 3.0.4

更新!
