Symfony 5 - Twig - 访问 entity.entityB.entityC.property 花费了许多请求

Question

on one of my pages, I display a list of clients, with information such as their country, or the name of their company.

So I proceeded as follows:

Repository:

    public function findAllAvailableCustomers()
    {
        return $this->createQueryBuilder('s')
            ->join('s.user', 'u')
            ->join('u.entreprise', 'e')
            ->leftJoin('s.subscription', 'ss')
            ->leftJoin('ss.plan', 'sp')
            ->addSelect('ss')
            ->where('e.willBeDeleted = false')
            ->orderBy('s.createdAt', 'DESC')
            ->getQuery()
            ->getResult();
    }

Twig:

//...

<td>{{ customer.user.email }}</td>
<td>{{ customer.denomination }}</td>
<td>{{ customer.user.entreprise.nom }}</td> // generates 11 requests

//...

I don't understand how I could alleviate the number of queries caused by displaying the client's company name.

I tried to add fetch="EXTRA_LAZY" at StripeCustomer.user and User.entreprise entity properties but nothing.

I tried also to add this at the request:

->addSelect('u, e, ss') but it generates 600 requests more

SO I don't know... :/

You should also select the enterprise entity in your first query:

public function findAllAvailableCustomers()
{
    return $this->createQueryBuilder('s')
        ->join('s.user', 'u')
        ->join('u.entreprise', 'e')
        ->leftJoin('s.subscription', 'ss')
        ->leftJoin('ss.plan', 'sp')
        ->addSelect('e') // <--- HERE
        ->addSelect('ss')
        ->where('e.willBeDeleted = false')
        ->orderBy('s.createdAt', 'DESC')
        ->getQuery()
        ->getResult();
}
