I just can’t understand one thing about symfony:

There are two such entities:

Receipt :

namespace AppBundle\Entity; use Doctrine\ORM\Mapping as ORM; use Symfony\Component\Validator\Constraints as Assert; use Gedmo\Mapping\Annotation as Gedmo; /** * Class Receipt * @ORM\Entity(repositoryClass="AppBundle\Repository\ReceiptRepository") * @ORM\Table(name="receipt") * * @package AppBundle\Entity */ class Receipt { /** * @var int * * @ORM\Id() * @ORM\Column(name="id", type="integer") * @ORM\GeneratedValue(strategy="AUTO") */ private $id; /** * @var string * @ORM\Column(name="shop", type="string", nullable=true) */ private $shop; /** * @var File * @ORM\ManyToOne(targetEntity="AppBundle\Entity\File", fetch="EAGER") * @ORM\JoinColumn(name="photo_id", nullable=true, onDelete="SET NULL") */ private $photoId; /** * @var \DateTime * @ORM\Column(name="date", type="datetime", nullable=true) */ private $date; /** * @var \DateTime * @ORM\Column(name="created_at", type="datetime") */ private $createdAt; /** * @var string * @ORM\Column(name="amount", type="string") */ private $amount; /** * @var ListItem * @ORM\OneToMany(targetEntity="AppBundle\Entity\ListItem", fetch="EAGER") * @ORM\Column(name="items", type="json_array", nullable=true) */ private $items; /** * @var User * @ORM\ManyToOne(targetEntity="AppBundle\Entity\User", fetch="EAGER") * @ORM\JoinColumn(name="user_holder", onDelete="SET NULL") */ private $user; /** * @return int */ public function getId() { return $this->id; } /** * @param int $id */ public function setId($id) { $this->id = $id; } /** * @return string */ public function getShop() { return $this->shop; } /** * @param string $shop */ public function setShop($shop) { $this->shop = $shop; } /** * @return File */ public function getPhotoId() { return $this->photoId; } /** * @param File $photoId */ public function setPhotoId($photoId) { $this->photoId = $photoId; } /** * @return \DateTime */ public function getDate() { return $this->date; } /** * @param \DateTime $date */ public function setDate($date) { $this->date = $date; } /** * @return \DateTime */ public function getCreatedAt() { return $this->createdAt; } /** * @param \DateTime $createdAt */ public function setCreatedAt($createdAt) { $this->createdAt = $createdAt; } /** * @return string */ public function getAmount() { return $this->amount; } /** * @param string $amount */ public function setAmount($amount) { $this->amount = $amount; } /** * @return string */ public function getItems() { return $this->items; } /** * @param array $items */ public function setItems($items) { $this->items = $items; } /** * @return User */ public function getUser() { return $this->user; } /** * @param User $user */ public function setUser($user) { $this->user = $user; } }

ListItem :

 namespace AppBundle\Entity; use Doctrine\ORM\Mapping as ORM; use Symfony\Component\Validator\Constraints as Assert; use Gedmo\Mapping\Annotation as Gedmo; /** * Class ListItem * * @ORM\Entity(repositoryClass="AppBundle\Repository\ListItemRepository") * @ORM\Table(name="`list_item`") * * @package AppBundle\Entity */ class ListItem { /** * @var int * * @ORM\Id() * @ORM\Column(name="id", type="integer") * @ORM\GeneratedValue(strategy="AUTO") */ private $id; /** * @var string * @ORM\Column(name="name", type="string", length=64, nullable=true) */ private $name; /** * @var string * @ORM\Column(name="shopName", type="string", length=64, nullable=true) */ private $shopName; /** * @var string * @ORM\Column(name="unit", type="string", length=64, nullable=true) */ private $unit; /** * @var int * @ORM\Column(name="quantity", type="float", nullable=true, columnDefinition="FLOAT") */ private $quantity; /** * @var int * @ORM\Column(name="price", type="string", nullable=true, nullable=true) */ private $price; /** * @var \DateTime * @ORM\Column(name="date", type="datetime", nullable=true) */ private $date;

/** * @var string * @ORM\Column(name="checked", type="integer", length=64) */ private $checked = 0; /** * @var File * @ORM\ManyToOne(targetEntity="AppBundle\Entity\File", fetch="EAGER") * @ORM\JoinColumn(name="photo_id", nullable=true, onDelete="SET NULL") * */ private $photoId;

/** * @var \DateTime * @ORM\Column(name="updated_at", type="datetime", nullable=true,) */ private $updatedAt; /** * @var \DateTime * @ORM\Column(name="deleted_at", type="datetime", nullable=true) */ private $deletedAt; /** * Get id * * @return integer */ public function getId() { return $this->id; } /** * Set name * * @param string $name * @return ListItem */ public function setName($name) { $this->name = $name; return $this; } /** * Get name * * @return string */ public function getName() { return $this->name; } /** * Set unit * * @param string $unit * @return ListItem */ public function setUnit($unit) { $this->unit = $unit; return $this; } /** * Get unit * * @return string */ public function getUnit() { return $this->unit; } /** * Set quantity * * @param integer $quantity * @return ListItem */ public function setQuantity($quantity) { $this->quantity = $quantity;

return $this; } /** * Get checked * * @return string */ public function getChecked() { return $this->checked; } /** * Set photoId * * @param \AppBundle\Entity\File $photoId * @return ListItem */ public function setPhotoId(\AppBundle\Entity\File $photoId = null) { $this->photoId = $photoId;

return $this; } /** * Get list * * @return \AppBundle\Entity\Lists */ public function getList() { return $this->list; } /** * Set createdAt * * @param \DateTime $createdAt * * @return ListItem */ public function setCreatedAt($createdAt) { $this->createdAt = $createdAt; return $this; } /** * Get createdAt * * @return \DateTime */ public function getCreatedAt() { return $this->createdAt; } /** * Set deletedAt * * @param \DateTime $deletedAt * * @return ListItem */ public function setDeletedAt($deletedAt) { $this->deletedAt = $deletedAt; return $this; } /** * Get deletedAt * * @return \DateTime */ public function getDeletedAt() { return $this->deletedAt; } /** * Set favorite * * @param integer $favorite * * @return ListItem */ public function setFavorite($favorite) { $this->favorite = $favorite; return $this; } /** * Get favorite * * @return integer */ public function getFavorite() { return $this->favorite; } /** * Set shopName * * @param string $shopName * * @return ListItem */ public function setShopName($shopName) { $this->shopName = $shopName; return $this; } /** * Get shopName * * @return string */ public function getShopName() { return $this->shopName; } /** * Set date * * @param \DateTime $date * * @return ListItem */ public function setDate($date) { $this->date = $date; return $this; } /** * Get date * * @return \DateTime */ public function getDate() { return $this->date; } /** * Set updatedAt * * @param \DateTime $updatedAt * * @return ListItem */ public function setUpdatedAt($updatedAt) { $this->updatedAt = $updatedAt; return $this; } /** * Get updatedAt * * @return \DateTime */ public function getUpdatedAt() { return $this->updatedAt; } }

In essence Receipt in the items field you need to put several ListItem .

How can this be achieved?

Pay attention to this class that implements the one-to-many relationship

 <?php namespace Test\TestBundle\Entity; use Tpg\ExtjsBundle\Annotation as Extjs; use Doctrine\ORM\Mapping as ORM; use JMS\Serializer\Annotation as JMS; use \Test\TestBundle\Entity\Car; /** * @Extjs\Model * @Extjs\ModelProxy("/mycarowners") * @ORM\Entity * @ORM\Table(name="car_owner") */ class CarOwner { /** * @ORM\Id * @ORM\Column(type="integer") * @ORM\GeneratedValue(strategy="AUTO") * @JMS\Type("integer") */ protected $id; /** * @ORM\OneToMany(targetEntity="Test\TestBundle\Entity\Car", mappedBy="carOwner") * @JMS\Type("ArrayCollection<Test\TestBundle\Entity\Car>") */ protected $cars; /** * Constructor */ public function __construct() { $this->cars = new \Doctrine\Common\Collections\ArrayCollection(); } /** * Get id * * @return integer */ public function getId() { return $this->id; } /** * Add cars * * @param Car $cars * @return CarOwner */ public function addCar(Car $cars) { $this->cars[] = $cars; $cars->setCarOwner($this); return $this; } /** * Remove cars * * @param Car $cars */ public function removeCar(Car $car) { $this->cars->removeElement($car); $cars->setCarOwner(null); } /** * Get cars * * @return \Doctrine\Common\Collections\Collection */ public function getCars() { return $this->cars; }
