PODoctrine 2 - Many-to-one of many-to-one lazy loading fails
text
Body
copied!<p>My problem is related to the lazy-loading functionality of Doctrine 2.</p> <p>Let's say I have these 2 Entities:</p> <ul> <li>Area</li> <li>Venue</li> </ul> <p>Here are quick specs:</p> <ul> <li>An Area can contain other areas (sub-areas...)</li> <li>A Venue is located in only 1 area</li> <li>Area::getFullName() should output "Parent area name (if any) > Area name"</li> </ul> <p>My PHP Entities are:</p> <pre><code>class Area extends AbstractEntity { /** * @ORM\ManyToOne(targetEntity="Area", inversedBy="children") */ private $parent; public function getFullName() { if (!isset($this->fullName)) { $this->fullName = ($this->getParent() ? $this->getParent()->name . ' > ' : '') . $this->name; } return $this->fullName; } class Venue extends AbstractEntity { /** * @ORM\ManyToOne(targetEntity="Area") */ private $area; </code></pre> <p>Let's say that area "Paris" contains a subarea named "Center"</p> <p>If I call:</p> <pre><code>$area = $repoArea->findByUrl("paris/center") echo $area->getFullName(); // --> "Paris > Center" </code></pre> <p>So far, so good.</p> <p>But let's say now, that the "Fouquet's" restaurant is one Venue in the center of Paris:</p> <pre><code>$venue = $repoVenue->findByName("Fouquet's"); echo $venue->getArea()->getFullName() // --> " > Center" </code></pre> <p>The parent area name (--> "Paris") is not output...</p> <pre><code>$this->fullName = ($this->getParent() ? $this->getParent()->name . ' > ' : '') . $this->name; </code></pre> <p>But the parent Area Proxy Object is not NULL. It is just not initialized. And so calling the property "name" returns NULL.</p> <p>It seems that "double" (or "many-to-one of many-to-one"...) lazy loading fails. Something like:</p> <pre><code>$venue->getArea()->get(Parent)Area()->name </code></pre>
