Python 使用日期和用户django保存文件

我正在制作一个上传页面，我想要一个模型，它将保存一个指向上传文件、日期和用户的链接。 我是django的新手，对表单和模型之间的关系以及如何传递数据感到困惑

我想制作一个1字段表单，它将是FileField和catch request.user和time on the go，然后将它们保存在数据库中 这是我目前的代码：

forms.py

class UploadForm(forms.Form):

    def __init__(self, *args, **kwargs):
        self.user = kwargs.pop('user',None)
        super(UploadForm, self).__init__(*args, **kwargs)

    docfile=forms.FileField(label="Select a file")

@login_required
def upload(request):

    if request.method == "POST":

        form=UploadForm(request.POST, request.FILES, user=request.user)

        if form.is_valid():
            #this is what i used to save the only the file
            #now i want to have file,user and upload date in db
            new_doc = Document(docfile=request.FILES['docfile'])
            new_doc.save()

            print(request.user)
            **???**-what do i insert here to pass user and time
            to the model and save it **???**


            return HttpResponseRedirect(reverse('after_upload'))

    else:


        form=UploadForm()

    return render(request, 'upload.html', {'form':form})

class Document(models.Model):

你可能需要这样做

型号.py

    def __init__(self, *args, **kwargs):
        self.user = kwargs.pop('user',None)
        super(UploadForm, self).__init__(*args, **kwargs)

    docfile=forms.FileField(label="Select a file")

@login_required
def upload(request):

    if request.method == "POST":

        form=UploadForm(request.POST, request.FILES, user=request.user)

        if form.is_valid():
            #this is what i used to save the only the file
            #now i want to have file,user and upload date in db
            new_doc = Document(docfile=request.FILES['docfile'])
            new_doc.save()

            print(request.user)
            **???**-what do i insert here to pass user and time
