Я пытаюсь загрузить каталог с большим количеством файлов dicom, используя Django и JQuery ajax. Размер каждого файла не более 600 Кб. Я могу загружать 200 файлов за раз. Если я увеличил количество файлов (попытался загрузить 14000 файлов), это не сработает. Сайт зависает и не показывает никаких ошибок. Может ли кто-нибудь помочь мне с этой проблемой? Я прикрепил свой код ниже. Заранее благодарим.
View.py:
def handle_uploaded_file(f,filePath):
with open(filePath+'/'+f.name, 'wb+') as destination:
for chunk in f.chunks():
destination.write(chunk)
def UploadScanView(request):
if request.method == 'POST':
form = create_scan_form(request.POST)
if form.is_valid():
scan = form.save(commit=False)
scan.project_id = form.cleaned_data.get('project_id')
directory_name = request.POST.get('directories')
json_to_dictionary = json.loads(directory_name)
print(json_to_dictionary)
for upload_file in request.FILES.getlist('file'):
file_path = settings.MEDIA_ROOT+'/'+os.path.dirname(json_to_dictionary[upload_file.name])
print(file_path)
if os.path.exists(file_path):
handle_uploaded_file(upload_file, file_path)
else:
os.makedirs(file_path)
handle_uploaded_file(upload_file,file_path)
return render(request, 'fileupload/basic_upload/scan_upload.html', {'form': form})
else:
form = create_scan_form()
return render(request, 'fileupload/basic_upload/scan_upload.html', {'form': form})
