我使用 RedBeanPHP。假设我有以下结构：

<?php
require_once 'redbean/RedBean/redbean.inc.php';

R::setup('sqlite:test.sqlite');

$user = R::dispense('user', 1);
$user->name = 'john';
R::store($user);

$post = R::dispense('post', 1);
$post->author = $user;
$post->text = 'great post';
R::store($post);

$comment = R::dispense('comment', 1);
$comment->post = $post;
$comment->author = $user;
$comment->text = 'great comment';
R::store($comment);

现在我想检索所有评论作者而不手动加载它们（即，我想避免类似的代码R::find('comment', 'post_id = ?', [1])）。我这样做：

$post = R::load('post', 1);
R::preload($post,
[
    'author' => 'user', //this makes $post->author->name work
    'comment',

    //what I've tried in order to get $post->comments[...]->author->name to work:
    //'comment.author',
    //'comment.author' => 'comment.user',
    //'comment.author' => 'user',
    //'author' => 'comment.user',
]);

echo 'post author: ' . $post->author->name
    . PHP_EOL;

foreach ($post->ownComment as $comment)
{
    echo 'comment: ' . $comment->text
        . ' by ' . $comment->author->name
        . PHP_EOL;
}

我的问题是它打印出这样的东西：

post author: john
comment: great comment by

如您所见，没有关于评论作者的信息。除了手动获取评论/作者之外，我能做些什么呢？

终于让它工作了：我不得不附加'ownComment.author' => 'user'到R::preload电话。
