如何使用RetrieveAPIView在Django Rest框架中基于特定字段检索数据?

首先,在URL中。py公司

urlpatterns = [
    path("items/<str:file_name>", SingleUploadItem.as_view()),
]

和视图中。py,

from rest_framework import status
from .models import fileUpload
from .serializers import FileUploadSerializer

class SingleUploadItem(RetrieveAPIView):

    queryset = fileUpload.objects.all()
    serializer_class = fileUploadSerializer

    def get(self, request, file_name):
        try:
            fileupload_obj = fileUpload.objects.get(fileName = file_name)
            return Response(FileUploadSerializer(fileupload_obj).data)
        except fileUpload.DoesNotExist:
            return Response(status = status.HTTP_400_BAD_REQUEST)

希望能有所帮助。
