I have ClassA mapped to the entity ClassB with ManyToOne relation (simple so far).
class ClassA{
/**
* #var string
* #ORM\Id
* #ORM\Column(name="keyA", type="string", length=255)
*/
private $keyA;
/**
* #var ClassB $classB
* #ORM\ManyToOne(targetEntity="ClassB", inversedBy="classAs")
* #ORM\JoinColumns({
* #ORM\JoinColumn(name="ClassB_keyB", referencedColumnName="keyB")
* })
*/
private $classB;
}
And this is the ClassB:
class ClassB{
/**
* #var string
* #ORM\Id
* #ORM\Column(name="keyB", type="string", length=255)
*/
private $keyB;
/**
*
* #var ClassC $classC
* #ORM\Id
* #ORM\ManyToOne(targetEntity="ClassC", inversedBy="classBs")
* #ORM\JoinColumns({
* #ORM\JoinColumn(name="ClassC_keyC", referencedColumnName="keyC")
* })
*/
private $classC;
/**
* #var ArrayCollection $classAs
* #ORM\OneToMany(targetEntity="ClassA", mappedBy="classB")
*/
private $classAs;
}
As you can notice the ClassB contains a composite primary key (2 entities and on column).
And this is the ClassC:
class ClassC{
/**
* #var string
* #ORM\Id
* #ORM\Column(name="keyC", type="string", length=255)
*/
private $keyC;
/**
* #var ArrayCollection $classBs
* #ORM\OneToMany(targetEntity="ClassB", mappedBy="classC")
*/
private $classBs;
}
Whene i try to display all entities of ClassA (using findAll()) I get this exception Missing value for primary key classC on ERP\................\ClassB
What am I missing here ?!
you have to create your own method at ClassARepository and add your join columns

I've been working on a multi users web application using symfony 3.4 framework with fos user bundle in order to easily manipulate users.
I've integrated the bundle and everything work fine except that the bundle features don't match my need when it comes to multi users through inheritance !
Is there any trick to implement the multi user inheritance in fos bundle ?
I've tried a lot of different tricks like changing the roles , changing the user model interface, using symfony groups but all of them seemed to be not working !
The thing that will solve [with an ugly way] my problem is to change the value of the discriminator column .
* #ORM\Table(name="fos_user")
* #ORM\InheritanceType("SINGLE_TABLE")
* #ORM\DiscriminatorColumn(name="typeutilisateur", type="string")
* #ORM\DiscriminatorMap({"Parent"="User","admin" =
"Administrateur","association"

Everytime i subscribe i get the row in the table but with a discriminator column value ="parent"
So is there any major way to get this done ? or at least to change the value of the discriminator column ?
Remove the DiscriminatorMap. If you don't create one, Doctrine will generate one automagically. So long as you don't go messing around with names of Entity objects (ie, change Person to Persona, or whatever) then that's your best bet. It's also more dynamic because if/when you add additional types, it will update it for you (when cache is removed).
See here, last bullet point quoted:
If no discriminator map is provided, then the map is generated automatically. The automatically generated discriminator map contains the lowercase short name of each class as key.
I have next entities:
/**
* Customer
*
* #ORM\Table(name="customer")
* #ORM\Entity()
*/
class Customer
{
/**
* #var int
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var Account[]|ArrayCollection
*
* #ORM\OneToMany(targetEntity="Account", mappedBy="customer")
*/
private $accounts;
/**
* #var Account
*
* #ORM\OneToOne(targetEntity="Account")
*
* #ORM\JoinColumns({
* #ORM\JoinColumn(name="id",referencedColumnName="customer_id"),
* #ORM\JoinColumn(name="default_account_id", referencedColumnName="id")
* })
*/
private $defaultAccount;
}
/**
* Account
*
* #ORM\Table(name="account")
*/
class Account
{
/**
* #var int
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var Customer
*
* #ORM\ManyToOne(targetEntity="Customer", inversedBy="accounts")
* #ORM\JoinColumn(nullable=false)
*/
private $customer;
}
Idea that customer has multiply accounts, onr of the account should be default for customer. I would like to use foreign key with multiply fields to ensure that default customer account belongs to this customer, but I'm getting next error:
Column name `customer_id` referenced for relation from MyBundle\Entity\Customer towards MyBundle\Entity\Account does not exist.
Actually there is no "customer_id" field on ORM level, because it is "customer.id" but I dont know how to reference it.
It seems that line #ORM\JoinColumn(name="id",referencedColumnName="customer_id"), is redundant. Try to configure this field as following:
/**
* #var Account
*
* #ORM\OneToOne(targetEntity="Account")
*
* #ORM\JoinColumn(name="default_account_id", referencedColumnName="id")
*/
private $defaultAccount;
By the way, I think it would be better if you just added a boolean column is_default into your Account entity.
How can I do this?

I don't know how to create a link tables with additional fields like the picture. Which association should I use? How to manage these relations in entities?
Usually when you need a many to many approach Doctrine let you define such behaviour with a simple annotation.
#ORM\ManyToMany(targetEntity="full_qualified_namespace")
#ORM\JoinTable(
name="game_schemas_players",
joinColumns={#ORM\JoinColumn(name="this_field_name", referencedColumnName="id")},
inverseJoinColumns={#ORM\JoinColumn(name="that_field_anem", referencedColumnName="id")}
)
This will instruct Doctrine to create a relation the current entity and the target entity.
But that's not your case. For what I can see from your model you need to add some field on the 'middle' entity.
Here what you may want to do:
class Product
{
[...]
/**
* #var ArrayCollection | ProductImage[]
*
* #ORM\OneToMany(targetEntity="ProductImage", mappedBy="product")
*/
private $productImages;
}
class Image
{
[...]
/**
* #var ArrayCollection | ProductImage[]
*
* #ORM\OneToMany(targetEntity="ProductImage", mappedBy="image")
*/
private $productImages;
}
as you can see as defined here either Product and Image have a oneToMany relation with a middle entity which will be named ProductImage**.
The last step will be to implement such entity:
class ProductImage
{
[...]
/**
* #var Image
*
* #ORM\ManyToOne(targetEntity="Image", mappedBy="image")
* #ORM\JoinColumn(name="image_id", referencedColumnName="id")
*/
private $image;
/**
* #var Product
*
* #ORM\ManyToOne(targetEntity="Product", mappedBy="product")
* #ORM\JoinColumn(name="product_id", referencedColumnName="id")
*/
private $product;
/**
* #ORM\Column(type="string", length=1024)
* #var string
*/
private $position;
}
The owning side of the relation both for Product and Image is still ProductImage.
As a side note in your entity is common practice to implement an add method in this fashion:
public function __contructor(){
$this->productImages = new ArrayCollection();
}
/**
* Add ProductImage
*
* #param ProductImage $productImage
* #return $this
*/
public function addDocument(ProductImage $productImage)
{
$productImage->addProductImage($productImage);
$this->documents->add($document);
return $this;
}
and then you can use such method with the following approach:
$product = new Product();
$image = new Image();
$productImage = new ProductImage($product,$image);
$product->addProductImage($productImage);
Don't forget to provide the usual setter method as Doctrine need them to initialize the entity.
Hope it helps, Regards.
I started using Doctrine and ran into trouble immediately. I have an entity defined as follows:
namespace AdminModule;
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Entity
* #ORM\Table(name="admin_user")
*/
class User extends \Nette\Object
{
/**
* #ORM\Id
* #ORM\Column(type="string", name="guid")
* #var string
*/
protected $id;
/**
* #ORM\Column(type="string")
* #var string
*/
protected $username;
/**
* #ORM\Column(type="string")
* #var string
*/
protected $password;
/**
* #ORM\Column(type="string")
* #var string
*/
protected $email;
/**
* #ORM\Column(type="datetime")
* #var datetime
*/
protected $registered;
/**
* #ORM\Column(type="datetime")
* #var datetime
*/
protected $last_login;
}
If I call
$u = $this->em->getRepository('AdminModule\User')->createQueryBuilder()
->select('u.username, u.id')
->from('AdminModule\User', 'u');
I get the RuntimeException stating that identifier property "id" is missing. However, when I run the above code with getQuery() and execute() it, it returns the result I want.
Can you help me out? If more information is needed, just tell me. Thank you.
I am looking for some help as to why my OneToMany relationship in doctrine only returns one value. My data model has three tables. Users, Authorization, and Applications. The Authorization table is the glue that maps users to applications and also contains an accesslevel field to indicate their level of access for that application.
I have a user that has three entries in authorization for three different applications, but for some reason, doctrine is only loading 1 of those authorization records. I've included my full data model below. The attribute in question is "authorization" in the Webusers table.
Anyone know what I am doing wrong?
class Webusers {
/**
* #var integer
*
* #ORM\Column(name="userid", type="integer", nullable=false)
* #ORM\Id
* #ORM\GeneratedValue(strategy="IDENTITY")
*/
private $userid;
/**
* #var \Doctrine\Common\Collections\Collection
*
* #ORM\ManyToMany(targetEntity="Applications", mappedBy="userid")
*/
private $applications;
/**
* #var \Doctrine\Common\Collections\Collection
*
* #ORM\OneToMany(targetEntity="Authorization", mappedBy="user")
*/
private $authorization;
/**
* Constructor
*/
public function __construct() {
$this->applications = new \Doctrine\Common\Collections\ArrayCollection();
$this->authorization = new \Doctrine\Common\Collections\ArrayCollection();
}
class Authorization {
/**
* #var integer
*
* #ORM\Column(name="accesslevel", type="integer", nullable=false)
*/
private $accesslevel;
/**
* #var integer
*
* #ORM\Column(name="applicationid", type="integer", nullable=false)
* $ORM\Id
*/
private $applicationid;
/**
* #var integer
*
* #ORM\Column(name="userid", type="integer", nullable=false)
* #ORM\Id
*/
private $userid;
/**
* #var \Webusers
*
* #ORM\ManyToOne(targetEntity="Webusers")
* #ORM\JoinColumn(name="userid", referencedColumnName="userid")
*/
private $user;
}
class Applications {
/**
* #var integer
*
* #ORM\Column(name="applicationid", type="integer", nullable=false)
* #ORM\Id
* #ORM\GeneratedValue(strategy="IDENTITY")
*/
private $applicationid;
/**
* #var string
*
* #ORM\Column(name="name", type="string", length=50, nullable=false)
*/
private $name;
/**
* #var \Doctrine\Common\Collections\Collection
*
* #ORM\ManyToMany(targetEntity="Webusers", inversedBy="applicationid")
* #ORM\JoinTable(name="authorization",
* joinColumns={
* #ORM\JoinColumn(name="applicationid", referencedColumnName="applicationid")
* },
* inverseJoinColumns={
* #ORM\JoinColumn(name="userid", referencedColumnName="userid")
* }
* )
*/
private $userid;
/**
* Constructor
*/
public function __construct()
{
$this->userid = new \Doctrine\Common\Collections\ArrayCollection();
}
}
I was able to fix this by making sure I specified both the webusers and application relationship as ManyToOne AND giving them the #ORM\Id property since they make up a composite primary key.
I think the main reason this was failing was because I had not associated authorization to applications.
The key points of my new model are as follows:
class Webusers {
/**
* #var \Doctrine\Common\Collections\Collection
* #ORM\OneToMany(targetEntity="Authorization", mappedBy="user")
*/
private $authorization;
}
class Authorization {
/**
*
* #ORM\Id
* #ORM\ManyToOne(targetEntity="Applications")
* #ORM\JoinColumn(name="applicationid", referencedColumnName="applicationid")
*/
private $application;
/**
*
* #ORM\Id
* #ORM\ManyToOne(targetEntity="Webusers")
* #ORM\JoinColumn(name="userid", referencedColumnName="userid")
*/
private $user;
}
class Applications {
/**
* #ORM\OneToMany(targetEntity="Authorization", mappedBy="application")
*/
private $authorization;
}
