Django Rest Framework返回dict而不是OrderedDicts

Question

我有一个带有两个附加SerializerMethodField字段的序列化器：

class BentoSerializer(ModelSerializer):

    zones = SerializerMethodField()

    lead_zone = SerializerMethodField()

    def get_zones(self, obj):

        zone_queryset = obj.get_zones()

        return ZoneSerializer(zone_queryset, many=True).data

    def get_lead_zone(self, obj):

        zone_queryset = obj.get_lead_zone()

        return ZoneSerializer(zone_queryset).data

    class Meta:

        model = Bento

        fields = ('lead_zone', 'zones', )

我需要将来自序列化器的数据嵌套为JSON（ZoneSerializer包含SerializerMethodField其自身的相似的s和正常模型字段），但它以OrderedDict的形式出现。

有没有一种方法可以配置序列化器，使其BentoSerializer(obj).data返回嵌套的JSON，我应该递归地将OrderedDicts转换为dict，还是有一些我不知道的获取未排序数据的其他序列化器方法？

非常感谢！

PS：当前示例数据来自通过串行器发送的工厂对象：

[OrderedDict([('order', 1), ('columns', [OrderedDict([('order', 1), ('blocks', [OrderedDict([('order', 1), ('block_type', 'Text'), ('blockcontent', 'Cum inventore sed fugit aliquam doloribus. Alias exercitationem odit asperiores rerum qui aperiam cum fugit.'), ('heading', 'Adipisci possimus dolore assumenda sapiente velit amet odio doloremque.')])]), ('sticky', False), ('weight', 12), ('is_slideshow', False)])]), ('has_background_image', False), ('is_lead', False), ('is_slideshow', False), ('background_image', None), ('background_treatment', 'dark')])]

<class 'rest_framework.utils.serializer_helpers.ReturnList'>

{'lead_zone': {'background_image': None,

               'background_treatment': 'dark',

               'columns': [OrderedDict([('order', 1), ('blocks', [OrderedDict([('order', 1), ('block_type', 'Image'), ('blockcontent', '/media/media/2018/06/22/adatestfile_SfZMYPw.png'), ('heading', 'Reprehenderit officiis aliquid inventore enim quibusdam inventore beatae.')])]), ('sticky', False), ('weight', 12), ('is_slideshow', False)])],

               'has_background_image': False,

               'is_lead': True,

               'is_slideshow': False,

               'order': 1},

Answer 1

这是@NicholasClaudeLeBlanc的答案的附录。我无法json.dumps在我的上下文中工作。django-rest-framework使用的实际JSON渲染器可以这样获得：from rest_framework.renderers import JSONRendererrenderer = JSONRenderer()renderer.render

您可以使用：class BentoSerializer(ModelSerializer):&nbsp; &nbsp; zones = SerializerMethodField()&nbsp; &nbsp; lead_zone = SerializerMethodField()&nbsp; &nbsp; def get_zones(self, obj):&nbsp; &nbsp; &nbsp; &nbsp; zone_data = ZoneSerializer(obj.zones, many=True)&nbsp; &nbsp; &nbsp; &nbsp; data_list = []&nbsp; &nbsp; &nbsp; &nbsp; for i in zone_data.data:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; data_list.append(dict(i))&nbsp; &nbsp; &nbsp; &nbsp; return data_list&nbsp; &nbsp; def get_lead_zone(self, obj):&nbsp; &nbsp; &nbsp; &nbsp; lead_zone_data = ZoneSerializer(obj.lead_zone, many=True)&nbsp; &nbsp; &nbsp; &nbsp; data_list = []&nbsp; &nbsp; &nbsp; &nbsp; for i in lead_zone_data.data:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; data_list.append(dict(i))&nbsp; &nbsp; &nbsp; &nbsp; return data_list&nbsp; &nbsp; class Meta:&nbsp; &nbsp; &nbsp; &nbsp; model = Bento&nbsp; &nbsp; &nbsp; &nbsp; fields = ('lead_zone', 'zones', )
