Question

我的目标是让用户将文件上传到用户特定的文件夹。

我得到的错误是

no such column: notendur_document.user_id

以下是我的views.py文件的相关部分。这是上传的地方。

@login_required
def list(request):
    # Handle file upload
    if request.method == 'POST':
        form = DocumentForm(request.POST, request.FILES)
        if form.is_valid():
            newdoc = Document(docfile = request.FILES['docfile'])
            newdoc.save()

            # Redirect to the document list after POST
            return HttpResponseRedirect(reverse('notendur.views.list'))
    else:
        form = DocumentForm() # An empty, unbound form

    # Load documents for the list page
    documents = Document.objects.all()

    # Render list page with the documents and the form
    return render_to_response(
        'notendur/list.html',
        {'documents': documents, 'form': form},
        context_instance=RequestContext(request)
    )

这是我的models.py文件：

def _upload_path(instance,filename):
    return instance.get_upload_path(filename)

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

    def get_upload_path(self,filename):
        return "media/uploads/"+str(self.user.id) + "/" + '%Y.%m.%d' + filename

根据相关的.html文件，错误发生在documents的{{1}}变量中。

在list()注册用户方法：

views.py

Answer 1

只需传递pk = True in theforeingkey 例如用户=模型.ForeignKey（User，pk = True）这将解决问题

没有这样的专栏 - Django
