Django是否在表单错误时重新填充文件字段？

本文介绍了Django是否在表单错误时重新填充文件字段？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

目前我有一些类似的东西：

Currently I have something like:

def my_view(request) if request.method == 'POST': form = MyForm(request.POST, request.FILES) if form.is_valid(): form.save() redirect() else: form = MyForm() return render_to_response('form.html', {'form': form})

在表单验证错误中，与request.POST相关联的所有字段都被重新填充，但request.FILES的字段为空。这是一个已知的Django限制，还是有什么可以对我的文件域进行重新填充？

On a form validation error, all the fields associated with request.POST are repopulated but the fields with request.FILES are empty. Is this a known Django limitation or is there something I can do to my the file fields repopulate?

推荐答案

不，和浏览器问题一样多的Django问题。文件字段不能用初始值填充，否则在不知情的情况下，有恶意的形式从用户的机器上传文件将是微不足道的。有关于django-users邮件列表中有关于此的几个线程： groups.google/group/django-users/browse_thread/thread/14922dca454e3782/ groups.google/group/django-users/browse_thread/thread/f9fb21ddb4039b33/

No and this isn't as much a Django issue as a browser issue. File fields cannot be populated with an initial value otherwise it would be trivial to have a malicious form to upload files from the user's machine without their knowledge. There have been a couple threads about this on the django-users mailing list: groups.google/group/django-users/browse_thread/thread/14922dca454e3782/ groups.google/group/django-users/browse_thread/thread/f9fb21ddb4039b33/
