Django Views redirect('homepage')

我被困住了，不明白為什么我的問(wèn)題來(lái)了：

• 我想返回上下文，如果對(duì)象存在，否則重定向到主頁(yè)，并提出錯(cuò)誤Objects.DoesNotExist文件.

這是我的密碼：

Views

class PageDetail(TemplateView):
    """
    Page View
    """
    template_name = 'page_detail.html'

    def get_context_data(self, **kwargs):
        context = super(PageDetail, self).get_context_data(**kwargs)

        try:
            context['news'] = News.objects.filter(is_active=True).order_by('-date_created')[:4]
        except:
            pass
        try:
            context['page'] = Pages.objects.get(slug=kwargs.get('slug'), is_active=True)
        except Pages.DoesNotExist:
            return redirect('homepage')
        return context

但我有個(gè)錯(cuò)誤：

raise TypeError('context must be a dict rather than %s.' % context.__class__.__name__)
TypeError: context must be a dict rather than HttpResponseRedirect.

告訴我你是否需要更多的信息

Thanks
