在json

Question

模型

class makitVerifications（models.Model）：

Matter_fk = models.ForeignKey(Matter,on_delete=models.CASCADE , related_name = "makit_validate")

user_fk =  models.ForeignKey('auth.User',on_delete=models.CASCADE ,  related_name = 'verification_by'   , )

串行

class UserVerifyCountSerializer（serializers.ModelSerializer）：

# Tried makit_validate = makitSerializer (read_only = True)

class Meta :

    model = makitVerifications
    fields = (  'user_fk', 'makit_validate', 'Matter_fk')

UserVerifyCountSerializer._declared_fields [＆＃39; makit_validate＆＃39;] = makitSerializer（read_only = True）

视图

class UserVerfiyCountViewSet（generics.ListCreateAPIView）：

serializer_class = UserVerifyCountSerializer

def get_queryset(self):

    queryset = makitVerifications.objects.all()

    return queryset

JSON

{     ＆＃34;计算＆＃34;：2，     ＆＃34; next＆＃34;：null，     ＆＃34;之前＆＃34;：null，     ＆＃34;结果＆＃34;：[         {             ＆＃34; user_fk＆＃34;：1，             ＆＃34; Matter_fk＆＃34;：1         }，         {             ＆＃34; user_fk＆＃34;：1，             ＆＃34; Matter_fk＆＃34;：1         }     ]

字段＆＃34; makit_validate＆＃34;预期JSON中缺少嵌套对象。如何在json中获取相关模型的嵌套对象。

我还尝试了文档中的示例，但JSON缺少相同的字段

此外，如何省略/禁用嵌套在上述序列化程序类

中的对象的字段

Makie Serilazer

类makitSerializer（serializers.ModelSerializer）：

kamaz = kamazSerializer(many=True,read_only=True)

facilities = FacilitiesSerializer (many =True,read_only=True)

class Meta :

    model = Makit

    fields = '__all__'

## Makit Model ##
class Makit (models.Model): 
    pincode = models.IntegerField()

    area = models.CharField(max_length=200)

    street = models.CharField(max_length=200)

    landmark = models.CharField(max_length=100,blank=True , null = True)

    contact_no= models.BigIntegerField()

来自doc：Serializer fields

尝试：

makit_validate = makitSerializer(source="the_field_you_find_makit" read_only = True)
