迁移cakephp 2.5代码以使用cakephp 3.0对象

Question

I migrating a 2.5 app to cakePHP 3.0 and I am updating my code to use the ORM objects after find() rather than the arrays.

In my 2.5 view I do an array find and count the results. But I cannot seem to access the object level I need to do the count in the new code.

2.5 Code:

<?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; ?>

Now my 3.0 code and the object I am trying access and count:

<?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; ?>

Object:

[
(int) 0 => object(App\Model\Entity\Course) {

    'id' => (int) 1,
    'name' => 'Manual Handling Training',
    'course_lenght' => object(Cake\I18n\Time) {

    ],
    '[dirty]' => [],

(int) 1 => object(App\Model\Entity\Course) {

    'id' => (int) 3,
    'name' => 'Treacys Hotel Induction Training',
    'course_lenght' => object(Cake\I18n\Time) {

        'time' => '2015-05-28T01:25:00+0000',
        'timezone' => 'UTC',
        'fixedNowTime' => false

        'modified' => object(Cake\I18n\Time) {

            'time' => '2014-12-08T00:07:18+0000',

            'course' => true,
            'course_module' => true
        ],
        '[dirty]' => [],
        '[original]' => [],

    ],
    '[dirty]' => [],
    '[original]' => [],
    '[virtual]' => [],
    '[errors]' => [],
    '[repository]' => 'Courses'

},
]

I have tried this but it is a bad mess of objects and arrays

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

****UPDATE

I have accessed the data by pointing in _jointable. This is surely not the best practice?

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

Seems okay to me, but you could do the count via find in your action code.

to avoid the join you could use the object access method...

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