python - 在 Django Rest Framework GET 调用中自定义 JSON 输出

Question

我正在尝试从 MySQL 数据库中检索过滤后的列表。查询本身看起来不错，但返回的 JSON 显示如下:

[
{
    "id": "0038",
    "name": "Jane Doe",
    "total_hrs_per_week": 6,
    "timezone": "America/Los_Angeles"
},
{
    "id": "0039",
    "name": "John Doe",
    "total_hrs_per_week": 10,
    "timezone": "America/Los_Angeles"
}]

当我需要构建的规范需要这个时:

{
"people":[
{
    "id": "0038",
    "name": "Jane Doe",
    "total_hrs_per_week": 6,
    "timezone": "America/Los_Angeles"
},
{
    "id": "0039",
    "name": "John Doe",
    "total_hrs_per_week": 10,
    "timezone": "America/Los_Angeles"
}]}

这是我的序列化程序

class PeopleListSerializer(serializers.ModelSerializer):
    id = serializers.CharField(source='id')
    name =serializers.CharField(source='name')
    total_hrs_per_week = serializers.IntegerField(source='total_hrs_per_week')
    timezone = serializers.CharField(source='timezone')

    class Meta:
        model = models.Person
        fields = ('id','name','total_hrs_per_week','timezone')

知道如何以这种方式包装返回的结果吗？

编辑:

我试过像这样将它包装在另一个序列化程序中

    class PeopleListWrapperSerializer(serializers.Serializer):
        people = PeopleListSerializer(many=True)

        class Meta:
            fields = ['people']

但这会引发以下错误:

Got AttributeError when attempting to get a value for field people on serializer PeopleListWrapperSerializer. The serializer field might be named incorrectly and not match any attribute or key on the Person instance. Original exception text was: 'Person' object has no attribute 'people'.

Answer 1

您可以通过覆盖 list() 方法来做到这一点。

class PeopleListView(ListAPIView):

    def list(self, request, *args, **kwargs):
        # call the original 'list' to get the original response
        response = super(PeopleListView, self).list(request, *args, **kwargs) 

        # customize the response data
        response.data = {"people": response.data} 

        # return response with this custom representation
        return response
