如何将文件自动上传到后端的文件中上传，而无需在前端进行手动选择

Question

我的models.py

from django.db import models

# Create your models here.
class Result(models.Model):
    Id = models.AutoField(primary_key=True, blank=False)
    Name = models.CharField(max_length=100)
    # Date = models.DateTimeField(auto_now=False, auto_now_add=False)
    # Comments = models.TextField(max_length=256)
    File = models.FileField(blank=False)

我的views.py

from django.shortcuts import render
from contextmapping.Connection import Connection

from rest_framework.response import Response 
from rest_framework.decorators import action
from django.shortcuts import render

from rest_framework import viewsets,status
from rest_framework.authentication import TokenAuthentication
from rest_framework.permissions import IsAuthenticated
from result.models import Result

class ResultViewSet(viewsets.ModelViewSet):
    queryset = Result.objects.all()
    serializer_class = Result
    authentication_classes = (TokenAuthentication,)
    permission_classes = (IsAuthenticated,)


    @action(detail=True,methods=['GET'])
    def resultfill(self,request,pk=None):
        
        response={'message':'its working'}
        return Response(response,status=status.HTTP_200_OK)

我在文件夹中有一个名为data1.py的文件，我想在url中运行resultfill函数。在型号中文件。如何实现？

您可以在文件字段中使用默认值并提供文件的路径。如果您已经在设置中设置了所有媒体和静态文件URL，则可以将“ data1.py”添加为默认值。

class Result(models.Model):
    Id = models.AutoField(primary_key=True, blank=False)
    Name = models.CharField(max_length=100)
    # Date = models.DateTimeField(auto_now=False, auto_now_add=False)
    # Comments = models.TextField(max_length=256)
    File = models.FileField(default='data1.py')

这将使您的对象链接到该文件，以为您具有“媒体/data1.py”为文件位置，以防万一您不从Frontend或后端上传自己的文件。
