我有自定义存储空间

import os
from django.core.files.storage import Storage


class AlwaysOverwriteFileSystemStorage(Storage):
    def get_available_name(self, name):
        """
        Directly Returns a filename that's 
        from what user input.
        """
        if self.exists(name):
    # Remove the existing file
        os.remove(name)
    # Return the input name as output
        return name

我想知道我应该在哪里放置他的AlwaysOverwriteFileSystemStorage.py文件以及settings.py如何定义DEFAULT_FILE_STORAGE

我的Django根文件夹是/ home/username/webapp

当我放DEFAULT_FILE_STORAGE = 'site.storage.AlwaysOverwriteFileSystemStorage',它返回一个

错误

导入存储模块site.storage时出错:"没有名为storage的模块"

我不熟悉Python/Django,任何帮助将不胜感激.谢谢.

当我将文件提交到 django 服务器并且文件名存在于目录中时，我遇到了问题。Django 不会覆盖该文件，但会在名称末尾添加一些字符。我怎样才能添加字符而不是 Django.

我的 model.py 看起来像这样

class UpLoadFile(models.Model):\n      user = models.ForeignKey(User, on_delete=models.CASCADE)\n      file = models.FileField()\n      uploaded_at = models.DateTimeField(default=timezone.now)\n\n      def __str__(self):\n          return self.file.name + \' (\' + self.user.username + \')\'\n

views.py 看起来像这样：

@login_required\ndef home(request):\n    if request.method == \'POST\':\n\n        if \'upload_file\' in request.POST:\n            form = UploadFileForm(request.POST, request.FILES)\n            form.instance.user = request.user\n            if form.is_valid():\n                messages.success(request, \'Datoteka {} je bila uspe\xc5\xa1no dodana\'.format(str(request.FILES["file"])))\n                form.save()\n                return HttpResponseRedirect(\'/\')\n\n        else:\n            messages.error(request, \'Datoteke {} ni bilo mogo\xc4\x8de dodati. Preveriti \xc4\x8de datoteka vsebuje podatke.\'\n                           .format(str(request.FILES["file"])))\n …
