如何让 "classic portlet" 显示在 Page 和 NewsItem 默认视图中？

Question

我使用 @@manage-portlets 将 "classic portlet" 与文件夹相关联，并且我希望该文件夹下的所有 NewsItem 和 Pages 项目也将显示此 portlet。但是我收到一个错误 "There was an error while rendering the portlet." 和以下追溯：

那么，如何才能让 "classic portlet" 显示在 Page 和 NewsItem 默认视图中？

Answer 1

您的理解是正确的：如果您在文件夹上设置 portlet，它也会显示在该文件夹或其任何子文件夹中的任何项目上（除非您明确阻止该 portlet）。

在您描述的情况下，portlet 呈现中存在错误：您需要了解为什么 menudatasenado 得到 AttributeError。

没有 portlet 代码很难帮到你。您似乎引用了无法从其他内容项访问的特定内容项 (menudatasenado)。
