Ligne 1: Ligne 1:
 +====== Is there a better way to handle the Doctrine proxy object ======
 +I have two classes linked with a one-to-one relation.
  
 +<code php>
 +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 $client;
 +    ...
 +    public function doSomething() {
 +        return 'something';
 +    }
 +    ...
 +}
 +</code>
 +
 +Those classes are loaded with database content with Doctrine. It is working perfectly when there is data in the database. But if there is not ClientInfo data, I have a //\Doctrine\ORM\EntityNotFoundException// raised.
 +
 +So I changed the doSomething() method to take this into account.
 +
 +<code php>
 +    public function doSomething() {
 +        if (!$this->getInfo() instanceof ClientInfo) {
 +            return false;
 +        }
 +        try {
 +            return $this->getInfo()->doSomething();
 +        } catch (\Doctrine\ORM\EntityNotFoundException $e) {
 +            return false;
 +        }
 +    }
 +</code>
 +
 +But it does not feel right to me since it is tied with //Doctrine//. I am trying to modify my unit tests to add a mock of the proxy object but it does not feel right either.
 +
 +Is there a better way of doing that?
 +
 +**EDIT 1**
 +
 +I followed Nico Kaag suggestion but it does not change anything.
 +
 +My constructor in my Client class look like this:
 +
 +<code php>
 +public function __construct() {
 +    $this->info = new ClientInfo();
 +}
 +</code>
 +
 +If I do a ''var_dump'' of //$this->info// after retrieving my object with Doctrine, this is what I get.
 +
 +<code>
 +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)
 +  ...
 +</code>
 +
 +**EDIT 2**
 +
 +I finally changed what I have done. I removed the try..catch block and change the query to retrieve objects from database. Now I force the query to retrieve the //ClientInfo// object at the same time as the //Client// object.
 +
 +This way, I can trust my test and if I forget to query both objects simultaneously, I will have an exception to remind it to me.
 +
 +<WRAP help>
 +See I have made classes for you.
 +
 +<code php>
 +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;
 +}
 +</code>
 +<code php>
 +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;
 +}
 +</code>
 +Try this, you will not get such issue.
 +
 +Also I have used bi-directional relation with cardinality one-to-one, parent connection 0:1*- (parent optional), please see the diagram.
