Question

我对Django比较新，但我试图为以下数据模型返回完整的JSON文档。

class Wheels(models.Model):
   w_name = models.CharField(max_length=255)
   w_weight = models.IntegerField(default=200)
   w_size = models.CharField(max_length=200)
   w_durability = models.IntegerField(default=45)

   def __str__(self):
    return self.w_name

class Chassis(models.Model):
    c_owner = models.CharField(max_length=255)
    c_year = models.IntegerField(default=1900)
    c_model = models.CharField(max_length=255)
    c_wheels = models.ForeignKey(Wheels)
    c_weight = models.IntegerField(default=20)

    def __str__(self):
      return self.c_model`

现在代码只返回：

{
"id": 1,
"c_owner": "Mike",
"c_year": 1969,
"c_model": "Chevy",
"c_weight": 3500,
"c_wheels": 1
}

但是我不想用轮子来代替轮子表

查看：

class ChassisList(ModelViewSet):
   queryset = Chassis.objects.all()
   serializer_class = ChassisSerializer


class WheelsList(ModelViewSet):
   queryset = Wheels.objects.all()
   serializer_class = WheelSerializer

串行器：

class WheelSerializer(serializers.ModelSerializer):
   class Meta:
    model = Wheels
    fields = ('__all__')

class ChassisSerializer(serializers.ModelSerializer):
   class Meta:
    model = Chassis
    fields = ('__all__')

Answer 1

简单的解决方案：

class ChassisSerializer(serializers.ModelSerializer):
   class Meta:
    model = Chassis
    fields = ('__all__')
    depth = 1

Django遵循主键JSON
