Symfony/Doctrine - createQueryBuilder orderBy

Question

我有一個'團隊'實體與財產'預算'。我只想打印球隊屬性，我希望擁有最大預算的球隊出現在第一名，第二名，第三名......（DESC）。

但使用此代碼，它不起作用，我不明白爲什麼。

的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(); 
}

<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實體

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

這裏，結果......

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£ 

切爾西...笑

Answer 1

在getAllTeamsSortedByDescBudget方法更改QueryBuilder查詢：

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

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