Question

I have a list that is pulled from three tables, Department, Type and User.

Displayed like this:

Film 
student      Jimmy Stewart
faculty      Cary Grant

from actions.class.php

$this->departments = Doctrine_Core::getTable('Department')
        ->createQuery('a')
        ->orderBy('a.name')
        ->execute();

indexSuccess.php

<?php foreach ($departments as $dept): ?>
      <tr>
        <?php check_for_id() ?>
        <td colspan="4" class="displayDept" valign="top"><?php echo $dept->getName() ?></td>
    </tr>
    <tr>
    <?php foreach ($dept->getUsers() as $user): ?>
    <tr>
      <td class="displayInfo" valign="top"><?php echo $user->getType() ?></td>
      <td class="displayInfo" valign="top"><a href="<?php echo $user->getUrl() ?>" target="_blank"><?php echo $user->getUrl() ?></a></td>
      <td class="displayInfo" valign="top"><?php echo simple_format_text($user->getDescription()) ?></td>
    </tr>
    <?php endforeach; ?>
   <?php endforeach; ?>

However, this results in the foreach pulling all id’s from the department table leaving some empty rows under the Department display. Like this:

Photography
student      Keanu Reeves
faculty      Lawrence Fishburn

Drawing

Film 
    student      Jimmy Stewart
    faculty      Cary Grant

Painting

Sculpture

Can I remove the departments that do not have a user id?

UPDATE

If I am going to use a join, how do I call that in the actions? This is where I am so far, but none of my iterations are working:

$this->departments = Doctrine_Core::getTable('Department')
        ->createQuery('a')
        ->leftJoin('a.Users p')
        ->orderBy('a.name ASC')
        ->execute();

I’m not sure what it does though. I can understand the WHERE as it would be in traditional php, but I cannot follow the symfony syntax. Am I even close??

Answer 1

Why not do it in the query, department joined with users?

UPDATE

this is from the top of my head, but it should be something like this:

$this->departments = Doctrine_Core::getTable('Department')
        ->createQuery('a')
        ->leftJoin('a.Users p')
        ->groupBy('a.id')
        ->having('COUNT(a.id) > 0')
        ->orderBy('a.name ASC')
        ->execute();
