Doctrine加入Entity并加入OneToMany

Question

我有名为Sections的实体，他们有：

/**
 * @ORM\OneToMany(targetEntity="Product", mappedBy="sections")
 */
protected $products;

名为Product的实体，其中包含：

/**
 * @ORM\OneToMany(targetEntity="Price", mappedBy="product")
 */
protected $price;

现在我用：

    $sectionsarray = $this->getDoctrine()
           ->getRepository('AsortBundle:Sections')
           ->createQueryBuilder('e')
           ->leftJoin('e.products', 'p')
           ->leftJoin('e.colors', 'c')
           ->select('e, p, c')
           ->orderBy('e.sequence', 'asc')
           ->addOrderBy('p.kolejnosc', 'asc')
           ->addOrderBy('c.sequence', 'asc')
           ->getQuery()
           ->getResult(\Doctrine\ORM\Query::HYDRATE_ARRAY);

我如何加入这些产品的价格？价格是数组，因为它有四种货币。

Answer 1

实体/ Product.php

 /**
 * @ORM\ManyToOne(targetEntity="Price", inversedBy="products")
 * @ORM\JoinColumn(name="price_id", referencedColumnName="id")
 */
private $price;

实体/ Price.php

 /**
 * @ORM\OneToMany(targetEntity="Product", mappedBy="price")
 */
private $products;

存储库/ SectionsRpository.php

  $sectionsarray = $this->getDoctrine()
       ->getRepository('AsortBundle:Sections')
       ->createQueryBuilder('e')
       ->leftJoin('e.products', 'p')
       **->leftJoin('p.price', 'pr')**
       ->leftJoin('e.colors', 'c')
       ->select('e, p, c, pr')
       ->orderBy('e.sequence', 'asc')
       ->addOrderBy('p.kolejnosc', 'asc')
       ->addOrderBy('c.sequence', 'asc')
       ->getQuery()
       ->getResult(\Doctrine\ORM\Query::HYDRATE_ARRAY);

Answer 2

您需要添加另一个联接：

$sectionsarray = $this->getDoctrine()
           ->getRepository('AsortBundle:Sections')
           ->createQueryBuilder('e')
           ->select('e, p, c, prices')
           ->leftJoin('e.products', 'p')
           ->leftJoin('p.prices', 'prices')
           ->leftJoin('e.colors', 'c')
           ->orderBy('e.sequence', 'asc')
           ->addOrderBy('p.kolejnosc', 'asc')
           ->addOrderBy('c.sequence', 'asc')
           ->getQuery()
           ->getResult(\Doctrine\ORM\Query::HYDRATE_ARRAY);

我使用的是价格而不是价格，因为代表一对多的字段应该是复数形式。

在会议中，我获得了当前的ISO格式，如PLN，USD，EUR，RUB。

现在我想从产品中得到他实际的货币价格，我保持会话，就像PLN一样。

Answer 4

好的我写了自定义的getter，现在工作得很好:)。

价格实体中的

：

/**
 * Get val
 *
 * @return string 
 */
public function getValWithCurrency()
{
    return array($this->currency->getIso() => $this->val);
}

在产品实体中：

/**
 * Get val
 *
 * @return string 
 */
public function getPriceArray()
{
    $arr = array();
    $pra = $this->price->toArray();
    foreach($pra as $k => $v){
        $a = $v->getValWithCurrency();
        $arr = array_merge($arr, $a);
    }
    return $arr;
}

enter image description here

我现在可以使用会话中的货币添加getter，或者像使用密钥一样使用货币会话。

为了得到所有：

    $c = $this->get('session')->get('currency');
    $sectionsarray = $this->getDoctrine()
           ->getRepository('AsortBundle:Sections')
           ->createQueryBuilder('e')
           ->select('e, p, c, prices, cur')
           ->leftJoin('e.products', 'p')
           ->leftJoin('p.price', 'prices')
           ->leftJoin('e.colors', 'c')
           ->leftJoin('prices.currency', 'cur')
           ->where('cur.iso = :sesscurr')
           ->setParameter('sesscurr', 'PLN')
           ->orderBy('e.sequence', 'asc')
           ->addOrderBy('p.kolejnosc', 'asc')
           ->addOrderBy('c.sequence', 'asc')
           ->getQuery()
           ->getResult(\Doctrine\ORM\Query::HYDRATE_ARRAY);

谢谢！
