Django文档对此进行了很好的解释：https://docs.djangoproject.com/en/4.0/topics/http/file-uploads/#basic-文件上传
我是Django的新手。我有一个可以上传多个文件的应用程序。我想通过包括经过身份验证的用户名和时间戳来重命名文件：
"bild.png"；应该变成"；bild_John_Bown202204055.png"；
我使用关于Django的MicrosoftGraph教程来进行身份验证(https://learn.microsoft.com/en-us/graph/tutorials/python)。任何人都可以帮助我将其包含在代码中。谢谢

def upload(request):
context = initialize_context(request)
user = request.session.get('user').get('name')
print(user)
if request.method == 'POST':
form = FilesForm(request.POST, request.FILES)
files = request.FILES.getlist('documents')
if form.is_valid():
for f in files :
newfile = UploadFiles(documents=f)
newfile.save()
else:
form = FilesForm()
# Load files for the list page
files = UploadFiles.objects.all()
context['files'] = files
context['form'] = form
return render(request, 'base/upload.html', context)
因此，不要使用newFile.save()，而是使用
from datetime import datetime
filename = f'{newFile.filename}_{user.username}_{datetime.now().strftime("%Y%m%d)"}'
with open(filename, 'wb+') as destination:
for chunk in newFile.chunks():
destination.write(chunk)
