Mam dwa entities - User i Training.
Postanowiłem do nich dorobić model łączący Timesheet (kótry w założeniu będzie przechowywał informacje o płatności, przyjęciu zaproszenia itp.)

    private $timesheets;
 
    public function __construct()
    {
        $this->timesheets = new ArrayCollection();
    }
 
    public function getTimesheets()
    {
        return $this->timesheets;
    }

Mam utworzonych kilku userów i kilka trainingów ale kiedy używam poniższego kodu w utworzonej tabeli dla Timesheet pola user_id oraz training_id zawierają NULL. Bardzo proszę o pomoc dla czego tak się dzieje. Może robię coś po drodze nie tak?

[PHP] pobierz, plaintext 
            $sheet = new Entity\Timesheet();
            $user = $this->_helper->Em()->find('Entity\User', 1);
            $training = $this->_helper->Em()->find('Entity\Training', 1);
            $user->getTimesheets()->add($sheet); 
            $training->getTimesheets()->add($sheet);      
            $this->_helper->Em()->persist($sheet);     
            $this->_helper->Em()->flush();

EDIT - PROBLEM ROZWIĄZANY

Trzeba wskazać obiekty w modelu Timesheets

Przykład:

[PHP] pobierz, plaintext 
            $sheet = new Entity\Timesheet();
            $user = $this->_helper->Em()->find('Entity\User', 4);
            $training = $this->_helper->Em()->find('Entity\Training', 2);
            $user->getTimesheets()->add($sheet); 
            $training->getTimesheets()->add($sheet);      
            $sheet->setUser($user);
            $sheet->setTraining($training);      
            $this->_helper->Em()->persist($sheet);     
            $this->_helper->Em()->flush();
