从Django Rest Framework响应中删除空字段

从Django Rest Framework响应中删除空字段

我发现此解决方案是最简单的。

from collections import OrderedDictfrom rest_framework import serializersclass NonNullModelSerializer(serializers.ModelSerializer):    def to_representation(self, instance):        result = super(NonNullModelSerializer, self).to_representation(instance)        return OrderedDict([(key, result[key]) for key in result if result[key] is not None])
