序列化

# tag的序列化
class TagSerializer(serializers.ModelSerializer):
    class Meta:
        model = models.Tag
        fields = '__all__'


# Depart的序列化
class DepartSerializer(serializers.ModelSerializer):
    class Meta:
        model = models.Depart
        fields = '__all__'


class UserSerializer(serializers.ModelSerializer):
    depart = DepartSerializer()
    # 不是一对一
    tags = TagSerializer(many=True)

    class Meta:
        model = models.UserInfo
        fields = '__all__'

view

class UserView(OrPermissionAPIView):

    def get(self, request, *args, **kwargs):
        # 多个对象
        queryset = models.UserInfo.objects.all()
        queryset = UserSerializer(instance=queryset, many=True)
        return Response(queryset.data)
