問題１

問題

relationの削除ができない

ソースコード

・Entity

/** * @ORM\OneToMany(targetEntity="HogeBundle\Entity\OrderDetail", mappedBy="order", cascade={"persist", "remove"}) */ protected $details;

1 2 3 4

/** * @ORM\OneToMany(targetEntity="HogeBundle\Entity\OrderDetail", mappedBy="order", cascade={"persist", "remove"}) */ protected $details;

・Controller:

$em = $this->get('doctrine')->getEntityManager(); $order = $em->getRepository('HogeBundle:Order')->find($id); foreach ($order->getDetails() as $detail) { $em->remove($detail); } $em->flush();

1 2 3 4 5 6 7

$em = $this->get('doctrine')->getEntityManager(); $order = $em->getRepository('HogeBundle:Order')->find($id); foreach ($order->getDetails() as $detail) { $em->remove($detail); } $em->flush();

対策

orphan-removalとremoveElementを使わないと行けないのようです。

ソースコード（解決）

・Entity

/** * @ORM\OneToMany(targetEntity="HogeBundle\Entity\OrderDetail", mappedBy="order", cascade={"persist", "remove"}, orphanRemoval=true) */ protected $details;

1 2 3 4

/** * @ORM\OneToMany(targetEntity="HogeBundle\Entity\OrderDetail", mappedBy="order", cascade={"persist", "remove"}, orphanRemoval=true) */ protected $details;

・Controller:

$em = $this->get('doctrine')->getEntityManager(); $order = $em->getRepository('HogeBundle:Order')->find($id); foreach ($order->getDetails() as $detail) { $order->getDetails()->removeElement($detail); } $em->flush();

1 2 3 4 5 6 7

$em = $this->get('doctrine')->getEntityManager(); $order = $em->getRepository('HogeBundle:Order')->find($id); foreach ($order->getDetails() as $detail) { $order->getDetails()->removeElement($detail); } $em->flush();

問題２

問題

Controllerで更新したのに、Templateに表示するrelationが古い

ソースコード

・Controller

$em = $this->get('doctrine')->getEntityManager(); $order = $em->getRepository('HogeBundle:Order')->find($id); // relationを追加 $detail = new OrderDetail(); $detail->setOrder($order); $em->persist($detail); $em->flush(); // templateに渡す return array( "order" => $order, );

1 2 3 4 5 6 7 8 9 10 11 12 13

$em = $this->get('doctrine')->getEntityManager(); $order = $em->getRepository('HogeBundle:Order')->find($id);   // relationを追加 $detail = new OrderDetail(); $detail->setOrder($order); $em->persist($detail); $em->flush();   // templateに渡す return array( "order" => $order, );

・Template

{% for detail in order.details %} {#...#} {% endfor %}

1 2 3

{% for detail in order.details %} {#...#} {% endfor %}

対策

Controllerでrefreshを使わなければなりません。

ソースコード（解決）

$em = $this->get('doctrine')->getEntityManager(); $order = $em->getRepository('HogeBundle:Order')->find($id); // relationを追加 $detail = new OrderDetail(); $detail->setOrder($order); $em->persist($detail); $em->flush(); // orderをrefresh $em->refresh($order); // templateに渡す return array( "order" => $order, );

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

$em = $this->get('doctrine')->getEntityManager(); $order = $em->getRepository('HogeBundle:Order')->find($id);   // relationを追加 $detail = new OrderDetail(); $detail->setOrder($order); $em->persist($detail); $em->flush();   // orderをrefresh $em->refresh($order);   // templateに渡す return array( "order" => $order, );
