我有一支团队'具有财产预算的实体'。我只想打印团队属性,我希望预算最多的团队出现在第一个位置,第二个,第三个......(DESC)。

但是使用此代码,它不起作用,我不明白为什么。

indexAction (控制器)

    $em = $this->getDoctrine()->getManager();
    $teams = $em->getRepository('FootballBundle:Team')->getAllTeamsSortedByDescBudget();


    return $this->render('FootballBundle:Default:index.html.twig', array(
        'teams' => $teams,
    ));

TeamRepository

public function getAllTeamsSortedByDescBudget()
{
    $q = $this->createQueryBuilder('a');
    $q->select()->from('FootballBundle:Team', 't')->orderBy('t.budget', 'DESC');

    return $q->getQuery()->getResult();
}

树枝视图

<h1>Teams list</h1>
<ul>
    {% for team in teams  %}
        <li>{{ team.name }} - {{ team.championship }} - {{ team.budget|number_format(2, '.', ',') }}£</li>
    {% endfor  %}
    <br/>
</ul>

Team.php 实体

/**
 * @var integer
 *
 * @ORM\Column(name="budget", type="integer")
 */
private $budget;

在这里,结果......

Teams list

Manchester City FC - Premier League - 100,000,000.00£
Arsenal FC - Premier League - 50,000,000.00£
Leicester City - Premier League - 20,000,000.00£
Crystal Palace FC - Premier League - 5,000,000.00£
Chelsea FC - Premier League - 100,000,000.00£

切尔西......哈哈

QueryBuilder方法中的getAllTeamsSortedByDescBudget查询更改为:

public function getAllTeamsSortedByDescBudget() 
{ 
    $qb = $this->createQueryBuilder('t')
        ->orderBy('t.budget', 'DESC');

    return $qb->getQuery()->getResult(); 
}

您还可以使用sort()执行排序。

public function getAllTeamsSortedByDescBudget() { 
$qb = $this->createQueryBuilder('t')
       ->sort('t.budget', 'DESC');
return $qb->getQuery()->getResult(); 
}
