use App\Entity\Booking;
use App\Entity\User;
use App\Entity\Routes;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;


class BookingType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options): void
    {
        $builder
            ->add('date')
            ->add('time')
            ->add('user', EntityType::class, [
                'class' => User::class,
                'choice_label' => 'username', // Replace 'username' with the actual property of User to be displayed
            ])
            ->add('routes', EntityType::class, [
                'class' => Routes::class,
                'choice_label' => 'name', // Replace 'name' with the actual property of Routes to be displayed
            ])
        ;

        // Deliberate error: Typo in method name
        $builder
            ->addr('missingMethod'); 
    }

    public function configureOptions(OptionsResolver $resolver): void
    {
        $resolver->setDefaults([
            'data_class' => Booking::class,
        ]);
    }
}

I made a crud controller using make:crud but when i try to add a new row in my SQL database i get this error: Object of class App\Entity\Routes could not be converted to string. Can anyone spot the error and help me fix it?

Hi NoobDeveloper69, you can try the following.

use App\Entity\Booking;
use App\Entity\User;
use App\Entity\Routes;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;


class BookingType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options): void
    {
        $builder
            ->add('date')
            ->add('time')
            ->add('user', EntityType::class, [
                'class' => User::class,
                'choice_label' => 'username', // Replace 'username' with the actual property of User to be displayed
            ])
            ->add('routes', EntityType::class, [
                'class' => Routes::class,
                'choice_label' => 'name', // Replace 'name' with the actual property of Routes to be displayed
            ])
        ;
    }

    public function configureOptions(OptionsResolver $resolver): void
    {
        $resolver->setDefaults([
            'data_class' => Booking::class,
        ]);
    }
}
