Answer 1

You have two mistakes in your "condidat" property.
You used One-To-Many (Bidirectional). If you want to have only one
candidate per "Universitaire" - then you have to use One-To-One (Bidirectional).
class Universitaire
{
## ...
/**
* Bidirectional One-To-One (Owning Side)
*
* #ORM\OneToOne(
* targetEntity="AppBundle\Entity\Condidat",
* inversedBy="universitaire",
* cascade={"persist", "remove"}
* )
* #ORM\JoinColumn(
* name="condiat_id",
* referencedColumnName="id"
* )
*/
private $condidat;
class Condidat
{
## ...
/**
* Bidirectional One-To-One (Inversed Side)
*
* #ORM\OneToOne(
* targetEntity="AppBundle\Entity\Universitaire",
* mappedBy="condidat",
* )
*/
private $universitaire;
If not, and One-To-Many was exactly you wanted to have, than you have to set in your __construct() that "condidat" is an array collection
public function __construct()
{
$this->condidat = new \Doctrine\Common\Collections\ArrayCollection();
}
If I were you I'd rather use "candidates" with "s" - to show, that this an arrayCollection.
As I've already said - your example is Bidirectional One-To-Many. In this case we use mappedBy and inversedBy. Entity, in which you set Join column is Owning side. And of course JoinColumn has to be in the "Candidate" entity. So:
class Universitaire
{
## ...
/**
* Bidirectional One-To-Many (Owning Side)
* Predicate: One Universitaire can have a lot of candidates
*
* #ORM\OneToMany(
* targetEntity="AppBundle\Entity\Condidat",
* mappedBy="universitaire",
* cascade={"persist", "remove"}
* )
*/
private $condidats;
class Condidat
{
## ...
/**
* Bidirectional Many-To-One (Owning Side)
* Predicate: Each Condidat belongs to one Universitaire
*
* #ORM\ManyToOne(
* targetEntity="AppBundle\Entity\Universitaire",
* inversedBy="condidats",
* )
* #ORM\JoinColumn(
* name="universitaire_id",
* referencedColumnName="id",
* onDelete="SET NULL"
* )
*/
private $universitaire;
I added onDelete="SET NULL". If you delete universitaire then in field universitaire of each "condidate" you will see null value.
