Python 当AmazonS3私有上传/下载在我的django视图中工作时，我如何让它们在管理中工作？

我试图通过amazon private s3获得上传和下载，但无法获得完整的循环。我已经非常接近了，但它有一个有趣的行为，如下所述

什么有效

• 从管理员上传
• 从管理员处下载
• 使用“我的团队”视图从我的模板下载

什么不起作用

• 从我创建的视图+模板上传不会改变数据库
• 奇怪的是，上传的行为就像表单是有效的一样，甚至当你在管理面板中查看时，就好像上传是在没有任何更改的情况下发生的一样

**版本** Django版本1.9.7

def my_team(request, challenge):
    """A page showing details of a teams in a challenge."""
    # Find the team that this user belongs to...
    team = Team.objects.filter(challenge=challenge, members__id=request.user.id).first()
    # Boot them out if they are not in any team.
    if not team:
        return redirect('challenges_list')
    special_form = SpecialForm(instance=team)
    upload_complete = False
    # POST
    if request.method == 'POST':
        special_form = SpecialForm(request.POST or None, request.FILES, instance=team)
        if special_form.is_valid():
            special_form.save()
            upload_complete = True
    # this template us also used in team-details
    return render(request, 'challenges/team_details.html', {
        'challenge': challenge,
        'upload_form': special_form,
        'team': team,
        'special_form': special_form,
        'upload_complete': upload_complete

您应该将

enctype=“multipart/form data”

属性添加到您的

标记中。没有它，

请求。文件

将为空
