Django Rest Framework - 嵌套序列化不起作用

Question

model.py

class Account(models.Model):
    name_Account= models.CharField(max_length=50, default='')
    fecha_nacimiento = models.CharField(max_length=150, default='')
    phone = models.CharField(max_length=150, default='')
    mail = models.CharField(max_length=150, default='')
    user_id = models.ForeignKey(User,on_delete=models.CASCADE)
    rol_id = models.ForeignKey(Rol,on_delete=models.CASCADE, null =True)

class Reclamo(models.Model):
    nameReclamo= models.CharField(max_length=50, default='')
    rut = models.CharField(max_length=20, default='')
    numpoliza = models.CharField(max_length=30, default='')
    detalle_diagnostico = models.CharField(max_length=200, default='')
    account_id = models.ForeignKey(Account,on_delete=models.CASCADE,null =True)
    date = models.DateField(auto_now=True)
    name_estado= models.CharField(max_length=50, default='Pendiente')
    num_claim= models.CharField(max_length=30, default=' ' ,blank = True)

serializer.py

class AccountSerializer(serializers.ModelSerializer):
    class Meta:
        model = Account
        fields = ('id', 'name_Account', 'fecha_nacimiento', 'phone', 'mail', 'user_id', 'rol_id')

class ReclamoSerializer(serializers.ModelSerializer):
    name_Account = AccountSerializer(many=False) #read_only=True no return, no error 
    class Meta:
        model = Reclamo
        fields = ('id','nameReclamo','rut','numpoliza','detalle_diagnostico','account_id','date','name_estado','num_claim', 'name_Account')

错误

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

我试过不同的例子，但我不能return我希望

Answer 1

属性 name_Account 不存在。您必须指向 account_id，因为那是指向 Account 模型的 ForeignKey。

class ReclamoSerializer(serializers.ModelSerializer):
    account_id = AccountSerializer(many=False)
    class Meta:
        model = Reclamo
        fields = ('id','nameReclamo','rut','numpoliza','detalle_diagnostico','account_id','date','name_estado','num_claim')
