I have a User Entity class and I craete a UserRepository.php in the same directory to put my custom methods in it, But when I use that in a contoller using this syntax it won't work:
my Repository:
namespace Doobin\UserBundle\Entity;
use Doctrine\ORM\EntityRepository;
class UserRepository extends EntityRepository
{
public function pageAccess($User=1,$Page='_home')
{
$stmt="Somthing to test";
return $stmt;
}
}
My controller to use repository:
use Doobin\UserBundle\Entity\User;
.
.
.
.
$em = $this->getDoctrine()->getManager();
$products = $em->getRepository('UserBundle:User')->pageAccess();
var_dump($products);
When I use it, It counld't find the pageAccess method.
Should I introduce the repository somewhere? becuase the tuturial itself didn't say anything.
In your User entity you should add annotation on the top of the class :
/**
* User.
*
* #ORM\Table(name="my_user")
* #ORM\Entity(repositoryClass="UserRepository")
*/
class User
{
}

I'm trying to make a custom Doctrine's ORM Repository and extend it but I can't find a way to make it work. So far this is what i have:
The original Repository
//AppBundle\Repository\LocaleRepository.php
namespace AppBundle\Repository;
use Doctrine\ORM\EntityRepository;
use JMS\DiExtraBundle\Annotation as DI;
class LocaleRepository extends EntityRepository
{
protected myCustomFunction(){
}
}
The extended Repository
//OfficeBundle\Repository\OfficeRepository.php
namespace OfficeBundle\Repository;
use AppBundle\Repository\LocaleRepository;
class OfficeRepository extends LocaleRepository
{
//Empty class
}
My entiy:
namespace OfficeBundle\Entity;
// some calls to traits
use Doctrine\ORM\Mapping as ORM;
/**
* Office
*
* #ORM\Table(name="office__office")
* #ORM\Entity(repositoryClass="OfficeBundle\Repository\OfficeRepository")
*/
class Office implements TranslatableInterface{
//...
}
And Finally the call:
$em = $this->getDoctrine()->getManager();
$this->getEntityManager();
$office=$em->getRepository('OfficeBundle:Office')->myCustomeFunction($slug);
This trows the exception:
Undefined method 'myCustomFunction'. The method name must start with either findBy or findOneBy!
If I place myCustomeFunction inside the OfficeRepository it works fine but it brings down the purpose of extendind the repository. Also, the repository loaded by the controller is the correct one, vardumping the class shows: 'OfficeBundle\Repository\OfficeRepository'.
Finally I'm using KNP DoctrineBehaviors(translatable) on the office entity.
You must make your method public if you are going to use it outside the repository class.
class LocaleRepository extends EntityRepository
{
public function myCustomFunction()
{
....
}
}
All of my query in Entity Repository needs to be filtered by user.
Now I want to know how can I access the currently logged in user in Entity Repository directly.
What I did today is to get the currently logged in user in my controller, through the use of $this->getUser() and then pass it to Entity Repository and this is not efficient.
You need to inject security.token_storage service into another one to get the current user, but as of Repository classes belong to Doctrine project, not Symfony, it is not recommended to do this.. May be there is a way to achieve it by creating custom entityManager class as described here, but I don't think it would a good solution..
Instead of customizing an entityManager better create a service which calls repository classes' methods, inject desired services into it.. Let Repository classes do their job.
Implementation would be something like this:
RepositoryClass:
class MyRepository extends EntityRepository
{
public function fetchSomeDataByUser(UserInterface $user)
{
// query
}
}
Service:
class MyService
{
private $tokenStorage;
public function _construct(TokenStorageInterface $tokenStorage)
{
$this->tokenStorage = $tokenStorage;
// other services
}
public function getSomeDataByUser()
{
$user = $this->tokenStorage->getToken()->getUser();
return $this->entityManager->getRepository(MyREPOSITORY)->fetchSomeDataByUser($user);
}
}
Usage:
public function someAction()
{
$dataByUser = $this->get(MYSERVICE)->getSomeDataByUser();
}
If you use JMSDiExtraBundle it can be done by adding setter injection:
use Doctrine\ORM\EntityRepository;
use JMS\DiExtraBundle\Annotation as DI;
class YourRepository extends EntityRepository
{
/** #var User current user entity */
protected $user;
/**
* #DI\InjectParams({
* "token_storage" = #DI\Inject("security.token_storage")
* })
*/
public function setSimplaManager(TokenStorageInterface $tokenStorage)
{
$token = $tokenStorage->getToken();
if (!is_object($user = $token->getUser())) {
// e.g. anonymous authentication
return;
}
$this->user = $user;
}
}
I am stuck with a problem please help me with it. Here is the scenarario:
I have an entity "User" and corresponding repository "UserRepository", inside my entity there are only getter and setter methods. All custom queries I have written to UserRepository. Now inside my UserController I am trying to access repository methods which I am not able to do so.
e.g.
User entity:
class User
{
...
public function getId()
{
return $this->id;
}
public function setId($id)
{
return $this->id=$id;
}
public function setProperty($property)
{
$this->property = $property;
}
public function getProperty()
{
return $this->property;
}
....
}
?>
UserRepository:
class UserRepository extends EntityRepository
{
public function findUsersListingById($id)
{
$queryBuilder = $this->getEntityManager()->createQueryBuilder();
$query = $em->createQuery(
"SELECT U
FROM UserEntityPathGoesHere
WHERE U.id IN (".implode(",", $id).")"
);
$users = $query->getResult();
return $users;
}
public function sayHelloWorld(){
echo ' Hello World';
}
}
?>
UserController
class UserController
{
...
$users=$this->getDoctrine()
->getRepository('MyUserEntityPath')
->findUsersListingById($ids);
//now I have multiple users I want to iterate through each user for associating additional data with each user
foreach($users as $user)
{
$temp = array();
//I am able to access getId method which is defined in User entity
$temp['id'] = $user->getId();
//however I am not able to access method from UserRepository, I tried something like below which gives me error call to undefined function sayHelloWorld
$temp['status'] = $user->sayHelloWorld();
....
}
}
....
How can I access repository methods for an entity? Is it possible ? If not then what are the alternatives for the solution?
Everything is possible however you should not access the entity's repository from the entity itself because of the separation of concerns.
See this Stackoverflow answer for more details.
Basically, the whole idea is that you want to have your application organized the following way.
In short:
Controller > Repository > Entities.
It should not go in the other direction otherwise it creates a mess.
If you want to go a bit further into the separation of concerns you could do the following.
Controller > Service > Repository > Entities
Alternative solutions:
Create a Twig extension that access a service (which access a repository) or a repository.
Create a method in your repository, call the method in your controller, map the data to IDs (keys of array are the IDs), pass the array to the template and then pull the data from the array using the entity IDs
Create a method in your repository, call the method in your controller, inject the data into your entities and access the data through the entity in your template.
There are probably others but you would know better how your application is organized.
If the bundle is Acme/DemoBundle, then one would expect at a minimum
User entity
namespace Acme/DemoBundle/Entity
use Doctrine\ORM\Mapping as ORM;
/**
*
* #ORM\Table(name="user")
* #ORM\Entity(repositoryClass="Acme/DemoBundle/Entity/UserRepository")
*/
class User
{
...
}
User repository
namespace Acme/DemoBundle/Entity
use Doctrine\ORM\Mapping as ORM;
class UserRepository extends EntityRepository
{
...
}
It is also true that with an array of ids, one can also do the following in a controller:
...
$em = $this->getDoctrine()->getManager();
$users = $em->getRepository("AcmeDemoBundle:User")->findAllById($idArray);
...
To iterate thru users in a controller, one can then use a foreach loop as in:
foreach ($users as $user) {
//each user is an array
...
$id = $user['id'];
...
}
or in a template:
{% for user in users %}
...
{{ user.firstName }}
...
{% endfor %}
You need to declare the UserRepository as an EntityRepository for your user entity. In your User entity add this annotation:
/**
* #ORM\Entity(repositoryClass="Acme\StoreBundle\Entity\UserRepository")
*/
See the docs for a more detailed description.
You can use the postLoad event from doctrine and inject everything you want into the entity. The event listener looks like:
<?php
namespace AppBundle\EventListener;
use AppBundle\Entity\MyEntity;
use Doctrine\ORM\Event\LifecycleEventArgs;
/**
* Class MyEntityListener
*/
class MyEntityListener
{
public function postLoad(LifecycleEventArgs $eventArgs)
{
/** #var MyEntity $document */
$document = $eventArgs->getEntity();
if(!($document instanceof MyEntity)){
return;
}
$document->setEntityManager($eventArgs->getEntityManager());
}
}
and service.yml:
services:
app.myentity.listener:
class: AppBundle\EventListener\MyEntityListener
tags:
- { name: doctrine.event_listener, event: postLoad }
Of cource your Entity needs the method setEntityManager and your're ready.
Am using symfony framework for my application. And to save records in database I want call the $this->getDoctrine()->getManager(); method in my entity class. But when I did that it gave me the error:
Call to undefined method getDoctrine(),
Can some one tell me what is the right way to do this.
My entity class is like:
namespace Acme\SuperbAppBundle\Entity;
use Symfony\Component\DependencyInjection\Container;
use Doctrine\ORM\Mapping as ORM;
class Users
{
/**
* #var integer
*/
private $id;
/**
* #var string
*/
private $firstName;
/**
* #var string
*/
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set firstName
*
* #param string $firstName
* #return Users
*/
public function setFirstName($firstName)
{
$this->firstName = $firstName;
return $this;
}
/**
* Get firstName
*
* #return string
*/
public function getFirstName()
{
return $this->firstName;
}
function __construct($firstName){
$this->setFirstName($firstName);
}
function save(){
$em = $this->getDoctrine()->getManager();
$em->persist($create);
$em->flush();
}
}
And my controller method is like:
public function test(){
$create = new Users('Rajat');
$create->save();
}
Your save method is attempting to call
$this->getDoctrine();
Whereby $this is the current Class, and any other Class it inherits. As it stands, your current Class, User, is standalone, and does not have a getDoctrine() method. If your Class were to extend the Controller Class, it would have access to that method:
class User extends Controller
I believe this simple fix will work, although it probably doesn't make real sense for it to extend Controller, as it is a User Entity, and unrelated to a Controller. A preferred, more advanced method, would be to inject the Doctrine service into the User class.
Ok, first of all Doctrine Entities :
Handle the entity generation and configuration
Declare the operations on the setters and getters.
If you wana save an object into your entity there it's your User, you have two way to store this user:
One:
You can use entity manager to store a user and the entity will help you to create the right object using the seters and getters:
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use PATH\TO\Users;
class ExampleController extends Controller
{
public function examplefunction()
{
$em = $this->getDoctrine()->getManager();
$entity = new Users();
$entity->setFirstName('Rajat');
$em->persist($entity);
$em->flush();
}
}
The other way is to create this entry using QueryBuilder but it's a bad way in your case.
Oh, i forgot please delete the save method in your entity Doctrine manager allready implement it.
Your controller probably doesnt extends Symfony\Bundle\FrameworkBundle\Controller\Controller ...
You should have controller defined like this example:
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
class DefaultController extends Controller
{
}
Entity class does not extends ContainerAware / Controller, so you can't call $this->getDoctrine()->getManager(). I don't think your Entity class should extend to a Controller. Because your entity class will become a controller instance just because you want to access the doctrine manager. That's a not good practice. What you can do is inject doctrine manager to your Entity class through services.
I wrote a blog few weeks ago regarding injecting services container and accessing through constructor. You can inject doctrine entity manager in the same way you inject services container. You can take a look at that if you like :- http://anjanasilva.com/blog/injecting-services-in-symfony-2/
Here's a nice question regarding injecting doctrine manager. Make sure you read the answer as well. :- Symfony 2 EntityManager injection in service
And another nice tutorial on injecting custom repository manager instead of injecting the whole entity manager. Which I believe even a good solution. :- http://php-and-symfony.matthiasnoback.nl/2014/05/inject-a-repository-instead-of-an-entity-manager/
Hope this helps to increase your understanding about Symfony 2.
Cheers!
I'd like to use, something like:
$em = $this->getEntityManager();
Inside a Entity.
I understand I should do this as a service but for some testing purposes, I want to access it from an Entity.
Is it possible to achieve that?
I've tried to:
$em = $this->getEntityManager();
$profile_avatar = $em->getRepository('bundle:Perfils')->findOneByUser($this-getId());
But isn't working.
Fatal error: Call to undefined method
Proxies\webBundleEntityUserProxy::getEntityManager() in
/opt/lampp/htdocs/web/src/Pct/bundle/Entity/User.php on line
449
Why am I trying to do it this way?
I've 3 kinds of users: Facebook, Twitter and MyOwnWebsite users. Each of them have differents avatar which links facebook's profile, twitter's or otherwise, if its myownwebsite user, I retrieve the avatar from a URL in a database. For now, I don't want to create a service, because I'm just trying to make it working, to test it, not to create a final deployment. So this is why I'm trying to call Entity manager from an Entity. I don't want, by now, to modify configuration files, just this entity.
As pointed out (again) by a commenter, an entity manager inside an entity is a code smell. For the OP's specific situation where he wished to acquire the entity manager, with the least bother, a simple setter injection would be most reliable (contrary to my original example injecting via constructor).
For anyone else ending up here looking for a superior solution to the same problem, there are 2 ways to achieve this:
Implementing the ObjectManagerAware interface as suggested by https://stackoverflow.com/a/24766285/1349295
use Doctrine\Common\Persistence\ObjectManagerAware;
use Doctrine\Common\Persistence\ObjectManager;
use Doctrine\Common\Persistence\Mapping\ClassMetadata;
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Entity
*/
class Entity implements ObjectManagerAware
{
public function injectObjectManager(
ObjectManager $objectManager,
ClassMetadata $classMetadata
) {
$this->em = $objectManager;
}
}
Or, using the #postLoad/#postPersist life cycle callbacks and acquiring the entity manager using the LifecycleEventArgs argument as suggested by https://stackoverflow.com/a/23793897/1349295
use Doctrine\Common\Persistence\Event\LifecycleEventArgs;
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Entity
* #ORM\HasLifecycleCallbacks()
*/
class Entity
{
/**
* #ORM\PostLoad
* #ORM\PostPersist
*/
public function fetchEntityManager(LifecycleEventArgs $args)
{
$this->setEntityManager($args->getEntityManager());
}
}
Original answer
Using an EntityManager from within an Entity is VERY BAD PRACTICE. Doing so defeats the purpose of decoupling query and persist operations from the entity itself.
But, if you really, really, really need an entity manager in an entity and cannot do otherwise then inject it into the entity.
class Entity
{
private $em;
public function __contruct($em)
{
$this->em = $em;
}
}
Then invoke as new Entity($em).
Best way is to use Life Cycle: #ORM\HasLifecycleCallbacks
And you can use the appropriate Event as you want to get result:
#postLoad
#postPersist
...
Calling the Entity Manager from inside an Entity is a bad practice! You should keep your entities as simple as possible.
For what purpose do you need to call the Entity Manager from an Entity?
What I think you should do is, instead of using the Entity Manager inside your entity, is to create a custom repository for your entity.
In your entity ORM file, add an entry as follows (or in your entity class annotations if not using YML):
App\Bundle\Profils:
# Replace the above as appropiate
type: entity
table: (your table)
....
repositoryClass: App\Bundle\CustomRepos\ProfilsRepository
# Replace the above as appropiate.
# I always put my custom repos in a common folder,
# such as CustomRepos
Now, create a new PHP class that has the namespace above:
//Your ProfilsRepository.php
<?php
namespace App\Bundle\CustomRepos;
use Doctrine\ORM\EntityRepository;
class ProfilsRepository extends EntityRepository
{
/**
* Will return the user url avatar given the user ID
* #param integer $userID The user id.
#return string The avatar url
*/
public function getUserProfile($userId)
{
$em = $this->getEntityManager();
$qb = $em->createQueryBuilder();
$qb->select... (your logic to retrieve the profil object);
$query = $qb->getQuery();
$result = $query->getResult();
return $result;
}
}
Finally, in your Controller:
// Your controller
<?php
namespace <class namespace>;
...
use App\Bundle\CustomRepos\ProfilsRepository;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
...
class YourClassNameController extends Controller
{
public function yourAction()
{
$userId = <get the user ID>;
// Pass the name of your entity manager to the
// getManager function if you have more than one and
// didn't define any default
$em = $this->getDoctrine()->getManager();
$repo = $em->getRepository('Profils');
$avatar = $repo->getUserProfile($userId);
...
}
}
You need to set the services.yml with:
services:
your_service_name:
class: AppBundle\Controller\ServiceController
arguments: [ #doctrine.orm.entity_manager ]
You need to set also the Controller with the following constructor:
public function __construct(\Doctrine\ORM\EntityManager $em)
{
$this->em = $em;
}
and use $this->em in the controller
(for example $connection = $this->em->getConnection();)
