Doctrine 2: How to handle join tables with extra columns

Question

How do I setup a join table with extra columns, or a many-to-many association with additional properties, in Doctrine 2?

Answer 1

In the second article, I suggest a minor update. Instead of the full event, use a LifecycleCallback within the entity itself:

/**
 * @ORM\Entity
 * @ORM\Table(name="jobs”)
 * @ORM\HasLifecycleCallbacks
 */
class Job
{
    // ...

    /**
     * @ORM\PreRemove
     */
    public function preRemoveCallback()
    {
        $this->setPerson(null);
        $this->setCompany(null);
    }
}
