我有一個帶有兩個附加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', )我需要將來自序列化器的數(shù)據(jù)嵌套為JSON（ZoneSerializer包含SerializerMethodField其自身的相似的s和正常模型字段），但它以O(shè)rderedDict的形式出現(xiàn)。有沒有一種方法可以配置序列化器，使其BentoSerializer(obj).data返回嵌套的JSON，我應(yīng)該遞歸地將OrderedDicts轉(zhuǎn)換為dict，還是有一些我不知道的獲取未排序數(shù)據(jù)的其他序列化器方法？非常感謝！PS：當(dāng)前示例數(shù)據(jù)來自通過串行器發(fā)送的工廠對象：[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},

這是@NicholasClaudeLeBlanc的答案的附錄。
我無法json.dumps在我的上下文中工作。django-rest-framework使用的實(shí)際JSON渲染器可以這樣獲得：
from rest_framework.renderers import JSONRenderer
renderer = JSONRenderer()
renderer.render

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