I have entity developer and comment and relationship Many comment to One developer. And I need form when I see all comment for developer and edit - add, delete in DB . What are the solutions to this problem
entity Comment:
class Comments
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #ORM\ManyToOne(targetEntity="Developer", inversedBy="comments")
* #ORM\JoinColumn(name="talent_id", nullable = true, referencedColumnName="id")
* */
protected $talent;
/**
* #var string
*
* #ORM\Column(name="added_by", type="string", length=10, nullable=true)
*/
private $added_by;
/**
* #var string
*
* #ORM\Column(name="comment", type="string", length=10, nullable=true)
*/
private $comment;
entity Developer:
class Developer extends CustomUser
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/////
/**
* #ORM\OneToMany(targetEntity="Comments", mappedBy="talent", cascade={"persist", "remove"})
*/
protected $comments;
Maybe need form in form but how to do this?
You are looking for field type collection.
Example usage of collection type
class Comments
{
....
/**
*
*#ORM\ManyToOne(targetEntity="Developer", inversedBy="developer_to_comments")
* #ORM\JoinColumn(name="developer_to_comments_id", referencedColumnName="id", nullable=false)
*
*/
private $comments_to_developer;
...
}
And class Developer
class Developer extends CustomUser
{
....
/**
*
* #var ArrayCollection
* #ORM\OneToMany(targetEntity="Comments", mappedBy="comments_to_developer", cascade={"remove"})
*/
private $developer_to_comments;
public function __construct()
{
$this->developer_to_comments = new ArrayCollection();
}
....
}
And don't forget use Doctrine\Common\Collections\ArrayCollection

I have a problem certainly very stupid .
I have 3 entities : activity , category and categorieActivite which the following codes :
/**
* Class Activite
* #ORM\Entity
* #ORM\Table(name="activite")
*/
class Activite{
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #ORM\Column(type="string",length=255)
*/
protected $nom;
/**
* #ORM\OneToMany(targetEntity="CategorieActivite",mappedBy="activite")
*/
protected $categorieList;
}
class Categorie{
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #ORM\Column(type="string",length=255)
*/
protected $nom;
/**
* #ORM\OneToMany(targetEntity="CategorieActivite",mappedBy="categorie")
*/
protected $activiteList;
}
class CategorieActivite{
/**
* #ORM\Id
* #ORM\ManyToOne(targetEntity="Categorie",inversedBy="activiteList")
* #ORM\JoinColumn(name="categorie_id", referencedColumnName="id", nullable=false)
*/
protected $categorie;
/**
* #ORM\Id
* #ORM\ManyToOne(targetEntity="Activite",inversedBy="categorieList")
* #ORM\JoinColumn(name="activite_id", referencedColumnName="id", nullable=false)
*/
protected $activite;
/**
* ORM\Column(type="string",length=50)
* #Assert\Choice(choices = {"Intense", "Douce", "Moyenne"}, message = "Veuillez choisir une valeur")
* #Assert\NotNull()
*/
protected $intensite;
}
So far all working properly. But the problem is that the intensity of CategorieActivite entity does not appear in the database , there are only foreign keys that appear. Do you have an idea of the problem?
Thank you in advance for your help.
Thibault.
On your $intensite property
* ORM\Column(type="string",length=50)
Should be:
* #ORM\Column(type="string",length=50)
Pretty sure that'll fix it for you. You'll need to run a doctrine:migrations:diff once you fix the annotation.
I have these 3 entitites

private $numberofjobsposted;
/**

sprovider.php
<?php
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**

class sprovider extends Users
{
/**

*/
private $address;
/**
* #var string
*
* #ORM\Column(name="postcode", type="string", length=255)
*/
private $postcode;
}
So I achieved that the extends statement provides the Users properties in the client and sprovider tables in MySQL. That's awesome. What I want now is to make the relations so that when I add a new client for example, both the tables Users and client add a new user/client in MySQL, and they have same id too.
the type() property in the Users entity i would like to be optional for the type of user I create. Example : I create a new client and in the Users table in MySQL the type is set to "CLIENT".
I read this and so far I think it has to be ManyToMany relation but It's quite confusing to me.
How to make those relations in the entities and then how to use them in the controller? If possible, please provide an example.
I think you're confused about the reasons to use inheritance.
The idea is that you have base class, in this case User, and that can be extended to provide variations of that class, in this case client (you should capitalise this) and sprovider.
Ideally, you would not have a User table, only the other 2.
In doctrine, this is called a mapped super-class.
A mapped superclass is an abstract or concrete class that provides persistent entity state and mapping information for its subclasses, but which is not itself an entity. Typically, the purpose of such a mapped superclass is to define state and mapping information that is common to multiple entity classes.
see the documentation here
you can link properties using relationships, this is their example.
<?php
/** #MappedSuperclass */
class MappedSuperclassBase
{
/** #Column(type="integer") */
protected $mapped1;
/** #Column(type="string") */
protected $mapped2;
/**
* #OneToOne(targetEntity="MappedSuperclassRelated1")
* #JoinColumn(name="related1_id", referencedColumnName="id")
*/
protected $mappedRelated1;
// ... more fields and methods
}
/** #Entity */
class EntitySubClass extends MappedSuperclassBase
{
/** #Id #Column(type="integer") */
private $id;
/** #Column(type="string") */
private $name;
// ... more fields and methods
}
I'm trying to create a "OneToMany" bidirectional association in my project but when I execute "doctrine:schema:update" nothing happens.
If I create this association directly from Sequel Pro and run the update schema command, that changes dissapear... :/
The relations is:
- One "id" from Customers Table with many "customer_id" form Control table.
Here is the Customers code:
<?php
namespace Ourentec\CustomersBundle\Entity;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\Mapping as ORM;
/**
* Customers
*
* #ORM\Table()
* #ORM\Entity
*/
class Customers
{
/* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var string
*
* #ORM\Column(name="name", type="string", length=100)
*/
private $name;
/**
* #var string
*
* #ORM\Column(name="lastname", type="string", length=100)
*/
private $lastname;
/**
* #var string
*
* #ORM\Column(name="address", type="text")
*/
private $address;
/**
* #var string
*
* #ORM\Column(name="phone", type="string", length=100)
*/
private $phone;
/**
* #var string
*
* #ORM\Column(name="pass", type="string", length=100)
*/
private $pass;
/**
* #var string
*
* #ORM\Column(name="tasks", type="text")
*/
private $tasks;
/**
* #var string
*
* #ORM\Column(name="status", type="string", length=100)
*/
private $status;
/**
* #var string
*
* #ORM\Column(name="email", type="string", length=100)
*/
private $email;
/**

*
* #ORM\Column(name="date", type="datetime")
*/
private $date;
/**
* #var string
*
* #ORM\Column(name="location", type="string", length=100)
*/
private $location;
/**
* #ORM\OneToMany(targetEntity="Control", mappedBy="customers")
*/
private $customer_id;
public function __construct()
{
$this->customer_id = new ArrayCollection();
}
And the Control code:
<?php
namespace Ourentec\CustomersBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* Control
*
* #ORM\Table()
* #ORM\Entity
*/
class Control
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var integer
*
* #ORM\Column(name="customer_id", type="integer")
*
* #ORM\ManyToOne(targetEntity="Customers", inversedBy="control")
* #ORM\JoinColumn(name="customer_id", referencedColumnName="id")
*/
private $customerId;
/**
* #var integer
*
* #ORM\Column(name="user_id", type="integer")
*/
private $userId;
/**
* #var \DateTime
*
* #ORM\Column(name="date", type="datetime")
*/
private $date;
/**
* #var integer
*
* #ORM\Column(name="seen", type="smallint")
*/
private $seen;
I followed the documentation from this 2 websites
http://symfony.com/doc/current/book/doctrine.html
http://librosweb.es/libro/symfony_2_x/capitulo_8/relaciones_y_asociaciones_de_entidades.html
But I don't know why it does not work..
Any idea will be appreciated :)
Mapping are not correct, I will try to explain how it works.
In Customers entity (you should rename it to Customer, entites names are singular)
/**
* #ORM\OneToMany(targetEntity="Control", mappedBy="customer")
*/
private $controls;
Mapped by option defines field name in the other entity.
/**
* #var integer
*
* #ORM\Column(name="customer_id", type="integer")
*
* #ORM\ManyToOne(targetEntity="Customers", inversedBy="controls")
* #ORM\JoinColumn(name="customer_id", referencedColumnName="id")
*/
private $customer;
Same thing with inversedBy.
In Customers entity you also need to init controls var as an ArrayCollection:
public function __construct()
{
$this->controls = new ArrayCollection();
}
With these mappings schema should be updated correctly.
For more info, check doctrine docs.
I'm getting a foreign constraint violation when trying to cascade delete entities having one-to-one and one-to-many bidirectional relations.
Here are my four entities related this way : the "User" object may have zero or one "Contact". Contact may have zero or one "Address" and zero or many "Telephone". But "Contact" must be related to a "User" entity, as well as "Address" and "Telephon"e with a "Contact" entity.
My aim is, when I delete a "User" all the child objects are cascade deleted too ("Contact", "Address" and "Telephone"). However, when I delete a child object, I just want its reference id in the parent entity to be set to NULL.
I've tried several ways including the options onDelete="CASCADE" and onDelete=NULL but I still get the foreign constraint violation error.

Try this configuration. I have only made changes to the #ORM\JoinColumn annotations by adding onDelete="CASCADE". This uses the built in database cascading so you will need to update your schema.
I have also removed some extraneous #ORM\JoinColumn(nullable=true) annotations on non owning sides of relations. These had no effect and were only misleading.

I nead help.
I have 3 entities. Book, Category And BookCategory - book can have multiple categories so i used another table.
I can easily acces Book and Category useing BookCategory table but i dont know how to do this by Book->BookCategory->Category.

How i need to config my entities or how to make my DQL to achive wanted results?
With your code, you only established the relationship from BookCategory to Book. As you said, that enables you to get the Book associated to one BookCategory.
To go the other way and get all BookCategory that belong to one book, you also need to specify this relationship. What you want is a OneToMany relationship from Book to BookCategory.
<?php
//...
use Doctrine\ORM\Mapping\OneToMany;
class Book
{
//...
/**
* #OneToMany(targetEntity="BookCategory", mappedBy="bookId")
*/
private $bookCategories;
//...
}
class BookCategory
{
//...
/**
* #var Book
* #ORM\ManyToOne(targetEntity="Book", inversedBy="bookCategories")
* #ORM\JoinColumn(name="book_id", referencedColumnName="id")
*/
private $bookId;
//...
}
After adding the necessary getters and setters, getBookCategories() will give you an Array with all BookCategory that belong to the Book.
For more details, have a look at the official Symfony2 documentation:
http://symfony.com/doc/current/book/doctrine.html#relationship-mapping-metadata
Edit:
Included use statement. Corrected inversedBy property for bookId.
