Всем привет. Делаю свой первый проект на Symfony. Возникла проблема с сохранением в базу данных при соотношении один ко многим. Доктрина выбрасывает такие ошибки:

The association ProjectBundle\Entity\Contact#departments refers to the inverse side field ProjectBundle\Entity\Departments#Contact which does not exist.
The association ProjectBundle\Entity\Departments#contact refers to the owning side field ProjectBundle\Entity\Contact#Departments which does not exist.

Подскажите пожалуйста в чем может быть проблема.

Вот код:

namespace ProjectBundle\Entity;

/**
 * Contact
 */
class Contact
{
    /**
     * @var int
     */
    private $id;

    /**

     */
    private $phone;

    /**
     * @var string
     */
    private $lastname;

    /**
     * @var string
     */
    private $email;

    /**
     * @var int
     */
    private $departmentId;


    /**
     * Get id

    }

    /**

    {
        $this->phone = $phone;

        return $this;
    }

    {

    }
