Trying to utilize inheritance, I've created the following entities:
/**
* #ORM\Table(name="persons")
* #ORM\Entity()
*/
class Person
{
/**
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #var string
*
* #ORM\Column(name="name", type="string", length=255)
*/
protected $name;
/**
* #ORM\OneToOne(targetEntity="Image", cascade={"persist"})
* #ORM\JoinColumn(name="image_id", referencedColumnName="id")
*/
protected $image;
}
/**
* #ORM\Table(name="actors")
* #ORM\Entity()
*/
class Actor extends Person
{
/**
* #ORM\Column(name="character", type="string", length=255)
*/
private $character;
}
/**
* #ORM\Table(name="images")
* #ORM\Entity()
*/
class Image
{
/**
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #ORM\Column(name="path", type="string", length=255)
*/
private $path;
}
Which almost works perfectly. The generated actors-table contains all the persons-fields, except for the image-relation. I've tried to change the relation to a ManyToOne, which didn't help.
How to make the Actor-entity also inherit all joined fields? I'm open to other solutions, if the above isn't ideal.
You need a parent construct in your Actor class:
public function __construct()
{
parent::__construct();
// your own logic
}
It is advised that you add an ID aswell.

i'm trying to make a manyToMany relationship with more attributes than the ids, so I need two OneToMany relationships and two ManytoOne relationships having three tables/entities.
I have Product entity, Client entity and ProductClient entity:
class Client
{
/**
* #var integer
*
* #ORM\Column(name="id_client", type="integer", nullable=false)
* #ORM\Id
* #ORM\GeneratedValue(strategy="IDENTITY")
*/
private $idClient;
/**
* #var string
*
* #ORM\Column(name="name", type="string", length=100, nullable=false)
*/
private $name;
/**
* #var \ProductClient
*
* #ORM\OneToMany(targetEntity="ProductClient", mappedBy="client")
*/
private $products_clients;
}
class Product
{
/**
* #var integer
*
* #ORM\Column(name="id_product", type="integer", nullable=false)
* #ORM\Id
* #ORM\GeneratedValue(strategy="IDENTITY")
*/
private $idProduct;
/**
* #var string
*
* #ORM\Column(name="name", type="string", length=100, nullable=false)
*/
private $name;
/**
* #var \ProductClient
*
* #ORM\OneToMany(targetEntity="ProductClient", mappedBy="product")
*/
private $products_clients;
}
class ProductClient
{
/**
* #ORM\Column(name="product_id", type="integer")
* #ORM\Id
* #ORM\ManyToOne(targetEntity="Product", inversedBy="products_clients")
* #ORM\JoinColumn(name="product_id", referencedColumnName="id_product", nullable=false)
*/
protected $product;
/**
* #ORM\Column(name="client_id", type="integer")
* #ORM\Id
* #ORM\ManyToOne(targetEntity="Client", inversedBy="products_clients")
* #ORM\JoinColumn(name="client_id", referencedColumnName="id_client", nullable=false)
*/
protected $client;
/**
* #var bool
*
* #ORM\Column(name="status", type="boolean")
*/
private $status;
}
That's something like this (with its getters and setters and more attributes). But symfony launches two "invalid entities errors" when I go to the Product crud:
AppBundle\Entity\Product - The association AppBundle\Entity\Product#products_clients refers to the owning side field AppBundle\Entity\ProductClient#product which is not defined as association, but as field.
AppBundle\Entity\Product - The association AppBundle\Entity\Product#products_clients refers to the owning side field AppBundle\Entity\ProductClient#product which does not exist.
And the same result if I go to the Client crud. What's wrong?
As you can see in the error message, AppBundle\Entity\ProductClient#product is not defined as association, but as field.
Just remove this #ORM\Column(name="product_id", type="integer") and this #ORM\Column(name="client_id", type="integer").
class ProductClient
{
/**
* #ORM\Id
* #ORM\ManyToOne(targetEntity="Product", inversedBy="products_clients")
* #ORM\JoinColumn(name="product_id", referencedColumnName="id_product", nullable=false)
*/
protected $product;
/**
* #ORM\Id
* #ORM\ManyToOne(targetEntity="Client", inversedBy="products_clients")
* #ORM\JoinColumn(name="client_id", referencedColumnName="id_client", nullable=false)
*/
protected $client;
/**
* #var bool
*
* #ORM\Column(name="status", type="boolean")
*/
private $status;
}
I'm facing a big problem with Doctrine when i'm requesting a table with a composite primary key referencing foreign keys.
I have a 3 entities:
Library(idLibrary,adress), Book(idBook,title,pageCount), Container(idLibrary,idBook, quantity).
Everything is generated without any errors but when i'm doing findAll() request on my Container repository my browser freezes and nothing is showed like it was stuck in a loop (there 3 rows in my Container table).

firstly, please use only French or English for class name and variable.
Add id inside class "Container" and remove annotation #ORM\id for attributes "library" and "book"
Define attribute "authors" with ArrayCollection and add method getAuthors(), addAuthor(Author $author), removeAuthor(Author $author)
And rename the tables name => "name_id" not "nameId"

I'm quite new to Symfony and Doctrine so....
In my application i have the following entities:
class Company
/**
* #ORM\Id()
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #ORM\Column(name="name", type="string", length=255)
* #ORM\OneToMany(targetEntity="\UserBundle\Entity\User", mappedBy="company")
* #ORM\OneToMany(targetEntity="\AppBundle\Entity\Account", mappedBy="company")
*/
protected $name;
public function __construct()
{
$this->name = new ArrayCollection();
}
UserClass (FOSUserBundle):
class User extends BaseUser
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #var string
*
* #ORM\Column(name="firstname", type="string", length=255)
*/
protected $firstname;
/**
* #var string
*
* #ORM\Column(name="name", type="string", length=255)
*/
protected $name;
/**
* #ORM\ManyToOne(targetEntity="\AppBundle\Entity\Company")
* #ORM\JoinColumn(name="company_id", referencedColumnName="id")
*/
protected $company;
and Accounts:
class Account
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var integer
*
* #ORM\Column(name="num", type="integer")
*/
private $num;
/**
* #var string
*
* #ORM\Column(name="name", type="string", length=255)
*/
private $name;
/**
* #ORM\ManyToOne(targetEntity="\AppBundle\Entity\Company")
* #ORM\JoinColumn(name="company_id", referencedColumnName="id")
*/
protected $company;
There are the following relations.
one company --> many users, many users --> one company;
one company --> many accounts; many accounts --> one company;
is it possible to generate the relations as i did by:
* #ORM\Column(name="name", type="string", length=255)
* #ORM\OneToMany(targetEntity="\UserBundle\Entity\User", mappedBy="company")
* #ORM\OneToMany(targetEntity="\AppBundle\Entity\Account", mappedBy="company")
--> two target entities?
thx for your help...
This is absolutely wrong. If you don't want any links from company to users and accounts then you can just omit this fields. And this relation will be unidirectional. You will have link to Company from both User and Account.
Just omit wrong mappings:
/**
* #ORM\Column(name="name", type="string", length=255)
*/
protected $name;
If you want to create link to users and accounts related to company you need to define fields for these ArrayCollections like that:
/**
* #ORM\OneToMany(targetEntity="\UserBundle\Entity\User", mappedBy="company")
*/
protected $users;
I have a series of classes with a slightly complicated set of references between the properties of those classes. I am trying to remove an entity and have that remove be cascaded to its children, but I'm running into foreign key constraint errors. Here is an example of my class structure:
<?php
/**
* #ORM\Entity
* #ORM\Table(name="student_tests")
*/
class StudentTest implements IEntityAccess {
/**
*
* #var int
* #ORM\Column(type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #var StudentTestItem[]
* #ORM\OneToMany(targetEntity="StudentTestItem", mappedBy="studentTest", cascade{"remove","persist"})
*/
protected $studentTestItems;
/**
* #var Test
* #ORM\ManyToOne(targetEntity="Test", inversedBy="studentTests")
*/
protected $test;
/**
* #var \DateTime
* #ORM\Column(type="datetime", nullable=true)
*/
protected $created;
/**
* #var User
* #ORM\ManyToOne(targetEntity="User", inversedBy="studentTests")
*/
protected $student;
}
//...
<?php
/**
* #ORM\Entity
* #ORM\Table(name="student_test_items")
*/
class StudentTestItem {
/**
*
* #var int
* #ORM\Column(type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #var StudentTest
* #ORM\ManyToOne(targetEntity="StudentTest", inversedBy="studentTestItems")
*/
protected $studentTest;
/**

*/
protected $student;
/**
* #var TestItem
* #ORM\ManyToOne(targetEntity="TestItem", inversedBy="studentTestItems", cascade{"persist"})
*/
protected $testItem;
}
//...
/**

*/
class Test implements IEntityAccess {
/**
*
* #var int
* #ORM\Column(type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #var \DateTime
* #ORM\Column(type="datetime", nullable=true)
*/
protected $startDate;
/**
* #var StudentTest[]
* #ORM\OneToMany(targetEntity="StudentTest", mappedBy="test" )
*/
protected $studentTests;
/**
* #var TestItem[]
* #ORM\OneToMany(targetEntity="TestItem", mappedBy="test", cascade={"all"})
*/
protected $items;
}
//...
/**
*
* #ORM\Table(name="test_items")
* #ORM\Entity
*/
abstract class TestItem {
/**
*
* #var int
* #ORM\Column(type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #var Test
* #ORM\ManyToOne(targetEntity="Test", inversedBy="items")
*/
/**
* #var StudentTestItem[]
* #ORM\OneToMany(targetEntity="StudentTestItem", mappedBy="testItem")
*/
protected $studentTestItems;
}
/**
* This is the primary user object. Used for login and all the other
* good stuff.
*
* #ORM\Table(name="users")
* #ORM\HasLifecycleCallbacks
class User implements AdvancedUserInterface, \Serializable, IEntityAccess
{
/**
* #ORM\Column(type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
* #var int
*/
private $id;
/**
* #var StudentTest[]
* #ORM\OneToMany(targetEntity="StudentTest", mappedBy="student", cascade={"persist", "remove"})
*/
protected $studentTests;
/**
* #var StudentTestItem[]
* #ORM\OneToMany(targetEntity="StudentTestItem", mappedBy="student", cascade={"persist", "remove"})
*/
protected $studentTestItems;
}
Let's say I want to delete a student test, and have that delete cascaded to its StudentTestItem children. To do so, I run the following code inside of a controller.
//... blah blah class definition
/**
* Delete a student test
*
* #return \Symfony\Component\HttpFoundation\Response
* #Route("/studenttest/delete", name="student_test_delete")
*/
public function DeleteStudentTestAction(Request $request)
{
$em = $this->getDoctrine()->getManager();
$studentTest = $em->getRepository("MyAcmeBundle:StudentTest")->findOneBy(array("id" => 3));
$em->remove($studentTest);
$em->flush();
return $this->redirect($this->generateUrl('student_delete_success'));
}
When I try to run that code, I get the following error message:
An exception occurred while executing 'DELETE FROM student_tests WHERE id = ?' with params [3]:
SQLSTATE[23000]: Integrity constraint violation: 1451 Cannot delete or update a parent row: a foreign key constraint fails (`my_acme_bundle/student_test_items`, CONSTRAINT `FK_71FA2A7F36BB1A1` FOREIGN KEY (`student_test_id`) REFERENCES `student_tests` (`id`))
500 Internal Server Error - DBALException
NOW, if I remove all references to studentTestItems from the classes, i.e. I comment out $studentTestItems from the TestItem and User classes, it deletes fine without that issue. Why is this happening? Does Doctrine keep track of the parent references through associations or something?
Looks like you forgot to add ON DELETE CASCADE to the foreign key constraint. Try changing the following association in class StudentTestItem:
/**
* #var StudentTest
* #ORM\ManyToOne(targetEntity="StudentTest", inversedBy="studentTestItems")
*/
protected $studentTest;
To this:
/**
* #var StudentTest
* #ORM\ManyToOne(targetEntity="StudentTest", inversedBy="studentTestItems")
* #ORM\JoinColumn(name="student_test_id", referencedColumnName="id", onDelete="CASCADE")
*/
protected $studentTest;
I have a Entity of TeamMembers. And the TeamMember can have a Specification with a value.
So I have three Entities: TeamMember, Specifications, SpecificationValues.
In the SpecificationValue table I want to store the TeamMember_id, the Specification_id and the value that is just for that TeamMember.
The Specifications and TeamMembers Entities are working. But now I want to show all the Specifications, if I go to the edit route (see code example) of a TeamMember, and have to possibility over there to fill in some values that I want to store in the SpecificationValue Entity.
[TeamMember > Specifications]: list of all specifications, with a extra input field where I can insert some values, that will be stored in the SpecificationValues entity.
<?php
namespace My\BundleName\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* SpecificationValue
*
* #ORM\Table()
* #ORM\Entity
*/
class SpecificationValue
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")

protected $id;
/**

protected $teammember;
/**

protected $value;
}

*/
protected $active = true;
}
And the Forms are generated with generate:crud.
this is how the form should look like > http://i.stack.imgur.com/Nkkdy.png
But is that even possible with Entities in Symfony?
