我需要使用使用比较标准(不仅是精确标准)的魔术查找器" findBy 方法.换句话说,我需要做这样的事情:
I'd need to use a "magic finder" findBy method using comparative criteria (not only exact criteria). In other words, I need to do something like this:
$result = $purchases_repository->findBy(array("prize" => ">200"));
这样我就可以购买所有奖励超过 200 的商品.
so that I'd get all purchases where the prize is above 200.
这是一个使用 Expr() Class - 几天前我也需要这个,我花了一些时间才知道确切的语法是什么及使用方式:
This is an example using the Expr() Class - I needed this too some days ago and it took me some time to find out what is the exact syntax and way of usage:
/**
* fetches Products that are more expansive than the given price
*
* @param int $price
* @return array
*/
public function findProductsExpensiveThan($price)
{
$em = $this->getEntityManager();
$qb = $em->createQueryBuilder();
$q = $qb->select(array('p'))
->from('YourProductBundle:Product', 'p')
->where(
$qb->expr()->gt('p.price', $price)
)
->orderBy('p.price', 'DESC')
->getQuery();
return $q->getResult();
}
