Django rest框架使用where查询进行部分更新

from rest_framework.generics import UpdateAPIView
from myapp.models import MyModel
from myapp.serializers import MyModelSerializer

class MyModelUpdateView(UpdateAPIView):
    queryset = MyModel.objects.all()
    serializer_class = MyModelSerializer

    def update(self, request, *args, **kwargs):
        # 获取需要更新的对象
        instance = self.get_object()

        # 使用where查询来指定更新的条件
        queryset = self.filter_queryset(self.get_queryset())
        queryset = queryset.filter(id=instance.id)  # 这里使用id作为条件，可以根据实际情况修改

        # 部分更新
        partial = kwargs.pop('partial', False)
        serializer = self.get_serializer(instance, data=request.data, partial=partial)
        serializer.is_valid(raise_exception=True)
        self.perform_update(serializer)

        return Response(serializer.data)
