I have the following error: Object of class App\Entity\Fournisseurs could not be converted to string I wish that in my order page we can choose a supplier to register in the db page and supplier page in order to associate an order with one or several suppliers I have however used the to_string command well so I do not see where the error is even if it must surely be stupid. I have try add to_sting command in orders.php and in fournisseurs.php ( fournisseurs = suppliers in french)

I use Symfony and EasyAdmin

CodePudding user response：

Try to move your function

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

in Fournisseurs.php instead of Orders.php and also rename

$this->sct_name

To

$this->name_sct

CodePudding user response：

You have to add toString function on Fournisseur. Your orders class has a relation with fournisseur, and symfony can't know what to display on your order form for the fournisseur input. So you have to explain in Fournisseur.php what is the string to show on the input.

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