Django - forms.FileField() 初始值 [英] Django - forms.FileField() initial value

问题描述

是否可以动态地为 forms.FileField() 赋予初始值?

Is it possible to give initial value for forms.FileField() dynamically?

推荐答案

根据安全标准， 不能有默认值，也不能被操纵.

By security standards, <input type="file"> can't have a default value and it can't be manipulated.

原因是，黑客可以将文件输入的默认值设置为您系统上的任何重要文件(包含密码、证书等)，使用 CSS 隐藏此字段，您将永远不会知道您已上传黑客托管的东西.

The reason is, that a hacker can set the default value of the file input to any important file on your system (containing passwords, certificates and so on), hide this field using CSS and you will never know that you have uploaded something to hackers host.
