遷移cakephp 2.5代碼以使用cakephp 3.0對象

Question

我將2.5應用程序遷移到cakePHP 3.0，並且正在更新代碼以在find()之后使用ORM對象，而不是使用數組。

在我的2.5視圖中，我進行數組查找並計算結果。 但是我似乎無法訪問需要在新代碼中進行計數的對象級別。

2.5代碼：

<?php foreach ($recentEmployees as $recentEmployee): ?>
    <tr>
        <td>
            <?php echo ($recentEmployee['Employee']['name']); ?>
        </td>
        <td><?php echo h($this->Time->format('d/m/Y', $recentEmployee['Employee']['created'])); ?></td>
        <td>
            <?php
                $completedCourses = count(
                                        array_filter(           
                                            $recentEmployee['Course'], 
                                            function($item){return $item['CoursesEmployee']['completed'];}  
                                                    )
                                        );
                $totalCourse = count($recentEmployee['Course']);      
            ?>
            <span class="label <?php echo($label); ?>">
            <?php 
                echo ($completedCourses); 
            ?>      
            /<?php echo ($totalCourse); ?>
        </td>
    </tr>
<?php endforeach; ?>

現在我的3.0代碼和我嘗試訪問和計數的對象：

<?php foreach ($recentEmployees as $recentEmployee): ?>
    <tr>
        <td><?= h($recentEmployee->name) ?></td>
        <td><?= h($this->Time->format($recentEmployee->created, 'd/M/Y')) ?></td>
        <td><?= debug($recentEmployee->courses) ?></td>
    </tr>
<?php endforeach; ?>

賓語：

我已經嘗試過了，但是對象和數組很爛

$completedCourses = count(
                        array_filter(
                            $recentEmployee->courses, 
                            function($item){return $item['CoursesEmployee']['completed'];}  
                                    )
                            );

**** UPDATE

我已經通過指向_jointable訪問數據。 這肯定不是最佳實踐嗎？

 <?= $completedCourses = count(
                            array_filter(
                                $recentEmployee->courses,
                                function($item){return $item['_joinData']['completed'];}
                                        )
                            );?>

Answer 1

對我來說似乎還可以，但是您可以通過在操作代碼中進行查找來進行計數。

為了避免聯接，您可以使用對象訪問方法...

<?= $completedCourses = count(
                            array_filter(
                                $recentEmployee->courses,
                                function($item){return $item->completed;}
                                        )
                            );?>
