and this error twig:

this is my controller call and my tables mark and car

controller:

class ShowRoomController extends AbstractController
{
    /**
     * Permet d'afficher l'ensemble des voitures du showrooms
     * @Route("/shows", name="show")
     */
    public function index( VoitureRepository $repo): Response
    {
        $shows = $repo->findAll();

        ]);
    }

                    {{show.mark}}
                    </div>

where is the error?

sorry for my basic english. I speak French at the base and thank you for your help.

CodePudding user response：

the error message is clear, the system could not convert an object of type Mark to string, so the solution is to use a property of the object $mark or implement the method __toString in the Mark class.

{{ show.mark.name }} for example.

OR

class Mark 
{
    ...

    public function __toString()
    {
        return $this->name;
    }

    ...
}

CodePudding user response：

you cant do this => {{show.mark}} mark is object is not a string

if you want to show the title of a Mark for exemple you need to do this =>{{show.mark.title}} if your mark entity has title
