Symfony/Doctrine - createQueryBuilder orderBy
我有一个带有属性预算"的团队"实体.我只想打印团队属性,我希望预算最大的团队出现在第一、第二、第三......(DESC).
I have a 'Team' Entity with a property 'budget'. I just want to print the teams properties and i want that the team with the biggest budget appear in first position, the second, the third... (DESC).
但是使用此代码,它不起作用,我不明白为什么.
But with this code, it does not work and i don't understand why.
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,
));
团队存储库
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
*
* @ORMColumn(name="budget", type="integer")
*/
private $budget;
这里,结果......
And here, the result ...
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

推荐答案
将 getAllTeamsSortedByDescBudget
方法中的 QueryBuilder
查询更改为:
Change your QueryBuilder
query in getAllTeamsSortedByDescBudget
method to:
public function getAllTeamsSortedByDescBudget()
{
$qb = $this->createQueryBuilder('t')
->orderBy('t.budget', 'DESC');
return $qb->getQuery()->getResult();
}
