How to persist nested Doctrine Entities correctly - doctrine-orm

I'm using Doctrine 2 in Zendframework 3.
I got an Order object with an 1:n relation to OrderAdditions which has a 1:1 Relation to OrderItems.
In the Order entity:
/**
* #ORM\OneToMany(targetEntity="LwsProject\Entity\OrderAddition", mappedBy="order", cascade={"persist", "remove"})
*/
protected $orderAdditions;
public function addOrderAdditions($orderAdditions) {
if($orderAdditions instanceof OrderAddition) {
$this->orderAdditions->add($orderAdditions);
$orderAdditions->setOrder($this);
}else if($orderAdditions instanceof ArrayCollection){
foreach($orderAdditions as $orderAddition){
$this->orderAdditions->add($orderAddition);
$orderAddition->setOrder($this);
}
}
return $this->orderAdditions;
}
public function removeOrderAdditions($orderAdditions) {
if($orderAdditions instanceof OrderAddition) {
$this->orderAdditions->removeElement($orderAdditions);
}else if($orderAdditions instanceof ArrayCollection){
foreach($orderAdditions as $orderAddition){
$this->orderAdditions->removeElement($orderAddition);
}
}
return $this->orderAdditions;
}
In the OrderAddition:
/**
* #ORM\OneToOne(targetEntity="\LwsProject\Entity\OrderItem", cascade={"persist", "remove"}, fetch="EAGER")
* #ORM\JoinColumn(name="order_item_id", referencedColumnName="id")
*/
protected $orderItem;
And in the OrderItem:
/**
* #ORM\OneToOne(targetEntity="LwsProject\Entity\OrderAddition")
* #ORM\JoinColumn(name="order_addition_id", referencedColumnName="id")
*/
protected $orderAddition;
Im Creating a new OrderAddition with a new OrderItem for several posted Items from a form.
// $order is either a new Order() or an entity from database.
$orderAddition = new OrderAddition();
//setting Data from post
$orderItem = new OrderItem();
//settign data from post
$orderAddition->setOrderItem($orderItem);
$orderItem->setOrderAddition($orderAddition);
$order->addOrderAdditions($orderAddition);
When I'm flushing while using $em->persist($order) with a new Order() everything gets persisted as expected, when im using an existing Order from the database i get:
SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'order_item_id' cannot be null

How to join column and target entity manually in manytoone relation?

I have two fields : account_type_id and account_id.
How can i manually map doctrine TargetEntity to join Company Entity if accountTypeId = 1 OR join User Entity if account_type_id = 2 ?
<?php
/** #Entity */
class Accounts
{
// 1= Company, 2 = User
private $accountType;
/**
* #ManyToOne(targetEntity="Companies")
*/
private $company;
/**
* #ManyToOne(targetEntity="Users")
*/
private $user;
//...
}
Unfortunately, joining different columns on the fly cannot be done automatically, but you can have both fields set as nullable and only set the correct one when persisting the Account entity.
This would be the annotation:
/**
* #ORM\ManyToOne(targetEntity="Users", inversedBy="users")
* #ORM\JoinColumn(name="user_id", referencedColumnName="id", nullable=true)
*/
private $user;
Keep in mind that nullable=true is the default anyway, I'm just being specific here.
If you want to go defensively about this, you can have an additional check in getter
/**
* #return User
* #throws \Exception
*/
public function getUser()
{
if ($this->accountType !== 2) {
throw new \Exception("Entity is not of type 'user'");
}
return $this->user;
}

API Platform - PATCH and ArrayCollection

I'm using API-Platform and faced an issue with updating many-to-many with an empty value.
Here is the small example:
/**
* Many Organizations have Many Followers.
* #ORM\ManyToMany(targetEntity="App\Entity\User\User", inversedBy="organizations")
* #ORM\JoinTable(name="organizations_followers",
* joinColumns={#ORM\JoinColumn(name="organization_id", referencedColumnName="id")},
* inverseJoinColumns={#ORM\JoinColumn(name="user_id", referencedColumnName="id", unique=true)}
* )
*/
protected $followers;
/**
* #return Collection
*/
public function getFollowers(): Collection
{
return $this->followers;
}
/**
* #param array $followers
*/
public function setFollowers(array $followers): void
{
$this->followers = $followers;
}
/**
* Organization constructor.
*/
public function __construct()
{
$this->id = Uuid::uuid4();
$this->followers = new ArrayCollection();
}
So, when I'm trying to delete all followers (PATCH request with empty followers in the relationships field) I always get one undeleted record. What am I doing wrong? Any Ideas?

How to set parent id on a child entity when submitting symfony3 form

How can I set the task_id on the TaskLine entity?

I get this error:
Neither the property "task_id" nor one of the methods "getTaskId()", "taskId()", "isTaskId()", "hasTaskId()", "__get()" exist and have public access in class "AppBundle\Entity\TaskLine"
NOTE: Normally I work with PropelORM.
I'm trying to save a new TaskLine entity which is related to Task entity. I'm posting JSON payload which look something like this.
{
"id": null,
"task_id": 1,
"note" : "new note"
}
In the controller I json_decode the request payload and submit that to $form->submit($note_data), $form is an instance of:
class TaskNoteType extends AbstractType
{
/**
* #param FormBuilderInterface $builder
* #param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add( 'task_id', NumberType::class )

*/
public function configureOptions(OptionsResolver $resolver)
{

Here is my Task entity
class Task

*/
private $description;
/**

private $id;
}

class TaskLine
{
/**

private $id;
/**

Best Practice for inserting objects with foreign keys in Symfony2
Answered by: Tuan nguyen
In ORM you have to set Foreign key by an object which your entity
associated with. You could use EntityManager#getReference to get a
reference to category entity without loading it from DB. Like this
$category = $entityManager->getReference('YourProject\Entity\Category', $categoryId);
$product = new Product();
$product->setCategory($category);

Doctrine: How to insert foreign key value
Following function you should have already in your Slider entity (or
similar).
public function addImage(Image $image) {
$image->setSlider($this); // This is the line you're probably looking for
$this->images[] = $image;
return $this; }
What it does is if you persist the entity it writes the ID of the Slider (sid) into your Image.
Doctrine 2 entity
association does not set value for foreign key
I found something in the Doctrine 2 documentation:
Changes made only to the inverse side of an association are ignored.
Make sure to update both sides of a bidirectional association (or at
least the owning side, from Doctrine’s point of view) As in my case
the owning side is the User I must update it. Doctrine 1 was able to
manage it automatically... too bad.

doctrine2 foreign key gets not created

I have two simple entities connected to each other with a OneToMany association.
/**
* #ORM\Entity(repositoryClass="Shopware\CustomModels\JoeKaffeeAbo\Client")
* #ORM\Table(name="joe_kaffee_abo_client")
*/
class Client extends ModelEntity
{
public function __construct() {
$this->abos = new ArrayCollection();
}
/**
* #ORM\OneToMany(targetEntity="Shopware\CustomModels\JoeKaffeeAbo\Abo", mappedBy="client", cascade= "all")
* #var \Doctrine\Common\Collections\ArrayCollection
*/
protected $abos;
public function addAbo($abo)
{
//$this->abos[] = $abo;
$this->abos->add($abo);
}
The second one is Abo:
/**
* #ORM\Entity(repositoryClass="Shopware\CustomModels\JoeKaffeeAbo\Abo")
* #ORM\Table(name="joe_kaffee_abo_abos")
*/
class Abo extends ModelEntity
{
/**
* #ORM\ManyToOne(targetEntity="Shopware\CustomModels\JoeKaffeeAbo\Client",inversedBy="abos")
* #ORM\JoinColumn(name="clientId", referencedColumnName="id")
*/
protected $client;
}
Somehow the join column gets not filled - it seems that doctrine ignores the association I set up. And if I call $client->addAbo($abo) there gets not relation created...and I cant receive the added abos via a getter function which returns the abo array collection.

Doctrine 2 - Insert new item in database

I'm trying to make something very simple.. but I do wrong, and I don't know what is the problem. Just I'm trying to insert new item to database with Doctrine 2:
$favouriteBook = new UserFavouriteBook;
$favouriteBook->user_id = 5;
$favouriteBook->book_id = 8;
$favouriteBook->created_at = new DateTime("now");
$this->_em->persist($favouriteBook);
$this->_em->flush();
As you can see.. is very simple, but that, give me next error:
Error: Message: SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'user_id' cannot be null
Obviosly, if I make a "dump" before "persist" and "flush" of $favouriteBook, all looks be correct..
This is my "favouriteBook" entity:
/** #Column(type="integer")
* #Id
*/
private $user_id;
/** #Column(type="integer")
* #Id
*/
private $book_id;
/**
* #ManyToOne(targetEntity="Book", inversedBy="usersFavourite")
* #JoinColumn(name="book_id", referencedColumnName="id")
*/
private $book;
/**
* #ManyToOne(targetEntity="User", inversedBy="favouriteBooks")
* #JoinColumn(name="user_id", referencedColumnName="id")
*/
private $user;
/** #Column(type="datetime") */
private $created_at;
public function __get($property) {
return $this->$property;
}
public function __set($property, $value) {
$this->$property = $value;
}
Anyone can image what is the problem? .. I don't know what else try.. Thanks
I think what beberlei is saying is that within your favouriteBook entity, you don't need to define the user_id and book_id as class properties, b/c the book and user properties you have set already recognize these as the relevant join columns. Also, your attempt to persist the favouriteBook entity failed because you need to set the book and user entity associations within the favouriteBook entity, not the foreign keys. So it would be:
$favouriteBook = new UserFavouriteBook;
$favouriteBook->book = $book;
$favouriteBook->user = $user;
$favouriteBook->created_at = new DateTime("now");
$this->_em->persist($favouriteBook);
$this->_em->flush();
You are mapping foreign keys and the associations. You have to modify the association not the foreign key field. Its bad-practice to map them both, you should remove $book_id and $user_id completly.
