Question

我按照此帖子的最高评论中的说明操作：Need a minimal Django file upload example这是我的views.py。我对创建文件列表不感兴趣，所以我删除了它。

def reikna(request):
    if request.method == 'POST':
        form = DocumentForm(request.POST, request.FILES)
        if form.is_valid():
            new_doc = Document(docfile = request.FILES['docfile'])
            # Marks the file as /options/ file
            new_doc.save()

            # Redirect to the document list after POST
            #return HttpResponseRedirect(reverse('notendur.views.options'))
    else:
        form = DocumentForm() # An empty, unbound form
    return render('file_view2.html', {'new_doc': new_doc})

然而，当我这样做时，我得到了

UnboundLocalError: local variable 'new_doc' referenced before assignment

这是否与new_doc的范围有关？我该怎么做？

编辑__我的模特

class Document(models.Model):
    docfile = models.FileField(upload_to=_upload_path)

    def get_upload_path(self,filename):
        return "uploads/"+str(self.user.id) + '/' + str(date.today()) + '/' + filename

将上传的文件传递给模板 - Django
