如何在 Django 中覆盖 'get_queryset()'

Question

我将在 Django 中使用通用视图。我定义了 serializer_class 并覆盖了 get_queryset() 方法，但是有一个错误告诉我要覆盖 get_queryset() 方法。我想知道我的 override 方法是怎么错的，我必须做些什么来解决这个错误。这是我的代码。

views.py

from .models import arduino
from .serializers import arduinoToAndroidSerializers, arduinoToDatabaseSerializers
from rest_framework.viewsets import ViewSet
from rest_framework.response import Response
from rest_framework.generics import ListCreateAPIView

class arduinoToAndroidViewSet (ViewSet) :
    def dataSend (self, request) :
        user = self.request.user
        queryset = arduino.objects.filter(name=user)
        serializer = arduinoToAndroidSerializers(queryset, many=True)
        return Response(serializer.data)

class arduinoToDatabaseViewSet (ListCreateAPIView) :
    serializer_class = arduinoToDatabaseSerializers
    def dataReceive (self, request) :
        user = self.request.user
        queryset = self.get_queryset()
        queryset = arduino.objects.filter(queryset, name=user)
        serializer = arduinoToDatabaseSerializers(queryset, many=True)
        return Response(serializer.data)

serializers.py

class arduinoToAndroidSerializers (serializers.ModelSerializer) :
    name = serializers.CharField(source='name.username')
    class Meta :
        model = arduino
        fields = ('name', 'temp', 'humi')

class arduinoToDatabaseSerializers (serializers.ModelSerializer) :
    class Meta :
        model = arduino
        fields = ('temp', 'humi')

除此之外，如果您在我的代码中看到改进点，请给我提示

您可以像这样覆盖查询集。有关详细信息，请参阅 docs 中的此处。

class arduinoToDatabaseViewSet (ListCreateAPIView) :
    serializer_class = arduinoToDatabaseSerializers
    
    <b>def get_queryset(self) :</b>
        user = self.request.user
        return arduino.objects.filter(name=user)
       </pre>
