Question

Laravel

$user = Auth::user();
$project = $user->roles()->first()->project()->first();
we get the current user, then we get the user's roles in various projects, select the first role and get the project where the user has a role.
and so a question in what, how in one request to receive a collection of all projects where the user has roles?

Answer 1

after a short dive into the documentation, I found the solution
$projects = $user->roles()->get()->transform(function($item){
return $item->project()->first();
});
