所以。我想找到這樣做的「正確」方式。我想檢索一個數據庫中所有條目的列表，以一種很好的，人類可讀的方式格式化「創建」和「修改」字段。查找方法返回時只調用全部（）
在Cakephp2.x中，我會使用afterFind方法。看到Cakephp3中沒有這個，我轉向這個blog post，發現我不得不使用formatResults函數。所以很自然，我想這（一樣的東西和許多其他迭代）：
public function findAllForView(Query $query, array $options)
{
$test = $query->formatResults(function ($results) {
$r = $results->map(function ($row) {
$row['created'] = new Time($row['created']);
$row['created'] = $row['created']->nice();
$row['modified'] = new Time($row['modified']);
$row['modified'] = $row['modified']->nice();
return $row;
});
return $r;
});
debug($test);
foreach ($test as $t) {
debug($t);
}
debug($test->all());
return $test;
}
變量$測試返回：

根據The Query builder part of the book，all()應返回結果集。然而，當$test->all()叫我得到這個驚喜：
object(Cake\Datasource\ResultSetDecorator) {
'count' => (int) 2
}
可能有人請點我在正確的方向？我很困惑，我可能只是使用toArray方法，但我仍然想知道爲什麼這不起作用，因爲我仍然在學習新的ORM系統。
