Question

如何在上传文件后列出文件？我想显示它们，以便以后查看和下载。

这是我的代码。

models.py

class UploadFile(models.Model):
    file = models.FileField(upload_to='files/%Y/%m/%d')

forms.py

class UploadFileForm(forms.ModelForm): pass

class Meta:
    model = UploadFile

views.py

@login_required(login_url='/accounts/login/')
def home(request):
    if request.method == 'POST':
        form = UploadFileForm(request.POST, request.FILES)
        if form.is_valid():
            new_file = UploadFile(file = request.FILES['file'])
            new_file.save()
            return HttpResponseRedirect(reverse('main:home'))
    else:
        form = UploadFileForm()
        data = {'form': form}
        return render_to_response('upload.html', data,
                                  context_instance=RequestContext(request))

无需从表单中恢复文件并保存 - 只需使用您的模型保存即可。视图必须是这样的：

    @login_required(login_url='/accounts/login/')
    def home(request):
        if request.method == 'POST':
        form = UploadFileForm(request.POST, request.FILES)
        if form.is_valid():
            form.save() # saving model instance
            return HttpResponseRedirect(reverse('main:home'))
        else:
            form = UploadFileForm()

        data = {'form': form}
        return render_to_response('upload.html', data, context_instance=RequestContext(request))

之后，您可以从模型中获取所有上传的文件：

files = [upload_file.file for upload_file in UploadFile.objects.all()]

并将其显示给用户
