Question

我试图在成功视图中访问通过HttpResponseRedirect（）传递的kwargs。密钥存在于kwarg dict中，但价值不是。这是为什么？

查看：

class UploadView(View):

    paneluploadform = PanelUploadForm

    def get(self, request, *args, **kwargs):

        paneluploadform = self.paneluploadform()
        context = {'paneluploadform': paneluploadform}
        return render(request, 'results/upload.html', context)


    def post(self, request, *args, **kwargs):

        paneluploadform = self.paneluploadform(request.POST, request.FILES)

        if paneluploadform.is_valid():
            panel_name = paneluploadform.upload()
            return HttpResponseRedirect(
                    reverse('results:success',
                    kwargs={'panel_name': panel_name})
                )


        context = {'paneluploadform': paneluploadform}
        return render(request, 'results/upload.html', context)


def success(request, *args, **kwargs):

    return render(request, 'results/success.html')

urls.py：

urlpatterns = [
    url(r'^upload/$', UploadView.as_view(), name='upload'),
    url(r'^upload/successful-(?P<panel_name>)', success, name='success')
]

在我的success.py视图中，print(kwargs)输出为{'panel_name': ''}

但我的网址是/ localhost / upload / successful-panelnameientered

为什么没有kwargs ={'panel_name': 'panelnameientered'}？

我不完全确定，但我认为您应该使用re_path，而且您没有设置模式以匹配successful-之后的模式。所以应该是这样的：

re_path(r'^upload/successful-(?P<panel_name>[a-z]+)', success)

Django：在传递视图中使用HttpResponseRedirect（reverse（））访问kwargs
