如何从Propel2中的非直接关系中获取值？

Question

我正在编写一个脚本，使用Propel2从我们的数据库中加载所有新闻 我目前的代码如下：

$news = NewsQuery::create()->find(); 

这给了我以下输出：

Array
(
    [0] => Array
        (
            [Id] => 1
            [Title] => Test News
            [Content] => hueheueheeueheu
            [CreatedAt] => 2018-03-29T00:00:00+00:00
            [Author] => 2
        )

    [1] => Array
        (
            [Id] => 2
            [Title] => gfdgdsfgfdg
            [Content] => sdfgfdgfdgfdgf
            [CreatedAt] => 2018-03-29T00:00:00+00:00
            [Author] => 2
        )
    [2] => Array
        (
            [Id] => 3
            [Title] => abcdef
            [Content] => ghijklm
            [CreatedAt] => 2018-03-29T00:00:00+00:00
            [Author] => 3
        )

)

如上面的输出所示，Author列返回添加它的用户的ID（通过与Users表的关系）。
我的目标是将Firstname Lastname从UserDetails作为Author列而不是用户的ID。 所以输出如下：

Array
(
    [0] => Array
        (
            [Id] => 1
            [Title] => Test News
            [Content] => hueheueheeueheu
            [CreatedAt] => 2018-03-29T00:00:00+00:00
            [Author] => John Doe
        )

    [1] => Array
        (
            [Id] => 2
            [Title] => gfdgdsfgfdg
            [Content] => sdfgfdgfdgfdgf
            [CreatedAt] => 2018-03-29T00:00:00+00:00
            [Author] => John Doe
        )
    [1] => Array
        (
            [Id] => 3
            [Title] => abcdef
            [Content] => ghijklm
            [CreatedAt] => 2018-03-29T00:00:00+00:00
            [Author] => Alice Smith
        )

)

这是我目前的计划：

如果不建立News到UserDetails的新关系（除非绝对必要），我怎样才能实现这一目标？

小旁注： 我很抱歉，如果我提出这个问题的流程有点过时，我一直在寻找解决方案大约两周......
