I have a form which has a FileField among other fields. Imagine the user chooses a file, presses submit and another field triggers a ValidationError. When I get back the form, with the errors on the page, what the user chose for the file field is gone. Can I make it appear, or is this a browser thing?
我有一个表单，其中包含FileField和其他字段。想象一下，用户选择一个文件，按下提交，另一个字段触发ValidationError。当我返回表单时，如果页面上出现错误，用户为文件字段选择的内容就不见了。我可以让它出现，还是浏览器？

This is a browser thing - for security reasons, you can't prepopulate a file input, otherwise it would be easy to trick users into uploading files from their system without their explicit action.
这是一个浏览器 - 出于安全原因，您无法预先填充文件输入，否则很容易诱使用户在没有明确操作的情况下从系统上传文件。
