Is there a better way to handle a Doctrine proxy object

Question

I have two classes related to the one-to-one relationship.

class Client { ... /** * @ORM\OneToOne(targetEntity="ClientInfo") * @ORM\JoinColumn(name="id", referencedColumnName="client_id") */ private $info; ... public function doSomething() { if (!$this->getInfo() instanceof ClientInfo) { return false; } return $this->getInfo()->doSomething(); } ... } class ClientInfo { ... /** * @ORM\Id * @ORM\OneToOne(targetEntity="Client") * @ORM\JoinColumn(name="client_id", referencedColumnName="id") */ private $client; ... public function doSomething() { return 'something'; } ... } 

These classes are loaded with the contents of the database using Doctrine. It works great when there is data in the database. But if there is no ClientInfo data, I get the message \ Doctrine \ ORM \ EntityNotFoundException.

Therefore, I modify the doSomething () method to take this into account.

  public function doSomething() { if (!$this->getInfo() instanceof ClientInfo) { return false; } try { return $this->getInfo()->doSomething(); } catch (\Doctrine\ORM\EntityNotFoundException $e) { return false; } } 

But this does not seem right to me, because it is connected with the Doctrine. I am trying to modify my unit tests to add a proxy object layout, but it also does not feel good.

Is there a better way to do this?

EDIT 1

I followed Nico Kaag's suggestion, but didn't change anything.

My constructor in my Client class is as follows:

 public function __construct() { $this->info = new ClientInfo(); } 

If I do var_dump from $ this-> info after retrieving my object using Doctrine, this is what I get.

 object(Proxies\__CG__\MyBundle\Entity\ClientInfo)[444] public '__initializer__' => object(Closure)[461] public '__cloner__' => object(Closure)[462] public '__isInitialized__' => boolean false private 'client' (MyBundle\Entity\ClientInfo) => string '21055' (length=5) ... 

EDIT 2

I finally changed what I did. I deleted the try..catch block and changed the request to retrieve objects from the database. Now I force the request to retrieve the ClientInfo object at the same time as the Client object.

That way, I can trust my test, and if I forget to request both objects at the same time, I will have an exception to remind me of this.

See what I did for you classes.

 use Doctrine\ORM\Mapping AS ORM; /** * @ORM\Entity */ class client { /** * @ORM\Id * @ORM\Column(type="integer") * @ORM\GeneratedValue(strategy="AUTO") */ private $id; /** * @ORM\OneToOne(targetEntity="Entities\client_info", inversedBy="client") * @ORM\JoinColumn(name="client_info_id", referencedColumnName="id", unique=true) */ private $clientInfo; }

 use Doctrine\ORM\Mapping AS ORM; /** * @ORM\Entity */ class client_info { /** * @ORM\Id * @ORM\Column(type="integer") * @ORM\GeneratedValue(strategy="AUTO") */ private $id; /** * @ORM\OneToOne(targetEntity="Entities\client", mappedBy="clientInfo") */ private $client; } 

Try this, you will not get such a problem.

I also used a bi-directional ratio with a power of one to one, the parent connection 0: 1 * - (parent optional), see the diagram.

Suggestetion: Use the ORM designer tool to design and retrieve entity classes.
