Question

我正在尝试创建一个自定义portelt，它根据关键字显示新闻或事件项。我不想使用收集portlet工具。我已经创建了一个Python脚本，它可以获得如下所需的结果：

from Products.CMFCore.utils import getToolByName
portal_catalog = getToolByName(context, 'portal_catalog')
return portal_catalog.searchResults(
                                    Subject = 'Startseite',
                                    end={'query': DateTime(),
                                         'range': 'min'},
                                    sort_on='start',
                                    sort_limit=3,
                                    review_state='external')[:5]

所以这应该使用review_state'external'和关键字（或主题）'Startseite'来获取所有对象。现在我创建了一个页面模板，用于渲染经典的portelt：

<html xmlns:tal="http://xml.zope.org/namespaces/tal"
      xmlns:metal="http://xml.zope.org/namespaces/metal"
      i18n:domain="plone">

     tal:define="view context/@@events_view;
                 results context/startpage_informations;
                 events_link view/all_events_link;
                 prev_events_link view/prev_events_link"
     tal:condition="results">

        <a href=""

           class="tile">
