在 Plone 中显示新闻项目创建者或所有者的全名

Question

我试图在列表中显示每条新闻的全名。目前我只有用户ID（昵称）。

有没有简单的方法（在现有的 .pt 文件中）显示创建者或所有者的全名而不是昵称？

该页面也必须适用于匿名用户。我的意思是 - 页面必须是 public.

一些细节：

<div class="container-fluid news-list-container"
     tal:define="news_items python:context.getFolderContents(contentFilter={'portal_type':['News Item'], 'sort_on': 'Date', 'sort_order': 'descending',});
                 Batch python:modules['Products.CMFPlone'].Batch;
                 b_size python:4;
                 b_start python:0;
                 b_start request/b_start | b_start;
                 batch python:Batch(news_items, b_size, int(b_start), orphan=0);"
     tal:condition="news_items">

  <div class="news-list-items">

    <tal:items tal:repeat="news_item batch">

      <!-- News item -->
      <div class="row news-item"
           tal:define="news_object python:news_item.getObject();
                       news_date python:news_object.getField('modification_date').getAccessor(news_object)();
                       news_title python:news_object.getField('title').getAccessor(news_object)();
                       news_description python:news_object.getField('description').getAccessor(news_object)();
                       news_image python:news_object.getField('image').getAccessor(news_object)();
                       news_url python:news_object.absolute_url();
                       news_creators python:news_object.getField('creators').getAccessor(news_object)(); .... ...

Answer 1

<tal:fullname define="membership context/portal_membership;
                      info python:membership.getMemberInfo(user.getId());
                      fullname info/fullname">
    You are are <span class="name" tal:content="fullname" />
</tal:fullname>

你可以从这段代码中得到很多启发：

https://github.com/collective/Products.Scrawl/blob/1021047c4ef6c2655d104e8b345a24140da9e4aa/Products/Scrawl/browser/blogentry_view.pt#L32

    <tal:name tal:condition="item_creator"
        tal:define="author python:context.portal_membership.getMemberInfo(item_creator)">
      <span i18n:translate="label_by_author">Posted by
      <a href="#"
         title="Read more posts by this author"
         tal:attributes="href string:${context/portal_url}/author/${item_creator}"
         tal:content="python:author and author['fullname'] or item_creator"
         tal:omit-tag="not:author"
         i18n:domain="scrawl"
         i18n:name="author"
         i18n:attributes="title author_title">
        Bob Dobalina
      </a>
      </span>
    </tal:name>

注意可能出现的性能问题。

缓存视图方法可能会更好，例如：

@memoize
def userid2fullname(self, userid):
     pm = api.portal.get_tool('portal_membership')
     memberinfo = pm.getMemberInfo(userid)
     return memberinfo and memberinfo['fullname'] or userid
