migrating cakephp 2.5 code to use cakephp 3.0 objects - php

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:

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'];}
)
);?>

Answer 1

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;}
)
);?>
