Answer 1

I won't discuss the logic of your relation, but It looks bidirectional and you have to define the owner and inverse sides using the mappedBy and inversedBy options.

I will answer your question straightforward:

to persist the related object in a OneToOne relation; user in this case, in your contact class add the cascad option like this:

/**
 * @ORM\OneToOne(targetEntity="tuto\welcomeBundle\Entity\User", cascade={"persist"})
 * @ORM\JoinColumn(nullable=false)
 */
 private $user ;
