如何在Django中上传文件后访问文件？

我正在开发一个网站。用户可以上传一个文件。这个文件是docx格式的。在他上传文件并选择他想要翻译文件的语言后，我想将他重定向到另一个页面，他可以在那里看到翻译的价格。价格取决于特定的语言和docx文件中的字符数。

我想不出如何处理上传的文件。我有一个函数，它得到文件路径并返回字符数。在上传文件并点击提交后，我想调用此函数，以便我可以呈现具有估计价格的新页面。

我已经阅读到我可以在request.FILES [\'file\']上调用temporary_file_path，但它会引发

\'InMemoryUploadedFile\' object has no attribute \'temporary_file_path\'

我希望找出上传的文件包含多少个字符并将其发送到另一个视图-/order-estimation。
