Django 用户特定文件夹

Question

我想为用户上传的文件创建专属的文件夹。这是我的 views.py 文件：

@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('upload.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(
        'upload/list.html',
        {'documents': documents, 'form': form},
        context_instance=RequestContext(request)
    )

这是我的 models.py 文件：

class Document(models.Model):
    docfile = models.FileField(upload_to='uploads/%Y.%m.%d')

我的想法是这样的。与其把文件夹命名为 uploads/%Y.%m.%d，我想在里面加上用户名。有没有办法做到这一点？

Answer 1

我在我的 models.py 文件里做了类似的事情：

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('auth.User')

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