视图.py：无法通过用户的电子邮件id在数据库中设置From的值，从该HTML表单上载文件不起作用，但在管理面板中它正常工作

def compose_msg(request):
    if request.method == 'POST':
        form = MessageForm(request.POST, request.FILES)
        if form.is_valid():
            form.From = request.user.email //Cant Set the value by this in Databse//
            instance = Message(File= request.FILES["File"])
            instance.save()
        return HttpResponseRedirect('/Portal/compose/')
    else:
        form = MessageForm()
    context = {
        "form":form,
    }
    return render(request,"form.html",context)

模型.py：程序中使用的模型

class Message(models.Model):
    subject = models.CharField(max_length=120)
    To = models.EmailField(max_length=254)
    From = models.EmailField(max_length=254)
    message = models.TextField(blank=True,
                               null=True)
    timestamp = models.DateTimeField(auto_now=False, auto_now_add=True)
    File = models.FileField(blank=True, null=True)

    def __unicode__(self):
        return self.subject

您应该像下面这样编辑form标记，因为文件上载需要^{} encoding：

<form role="form" class="form-horizontal" method="post" enctype="multipart/form-data">

编辑：要修改From值，可以执行以下操作：
