Laravel get only users which they have specific Role using RelationShip - php

Question

In my Laravel implemented web application i have Users and Roles tables with models which they are ManyToMany.
i want to get all users which they have specific role, for example:
$users = User::with(['roles' => function ($query) {
$query->whereLabel('is-portal-manager');
}])->get();
unfortunately this code return all users and compare role label and return that in relation ship array
Illuminate\Database\Eloquent\Collection {#2069 ▼
#items: array:3 [▼
0 => App\User {#2076 ▼
...
#relations: array:4 [▼
"properties" => null
"child" => Illuminate\Database\Eloquent\Collection {#2073 ▶}
"parent" => null
"roles" => Illuminate\Database\Eloquent\Collection {#2087 ▼
#items: array:1 [▼
0 => App\Entities\Role {#2074 ▼
...
#attributes: array:5 [▼
"id" => 1
...
"label" => "is-portal-manager"
...
]
...
}
]
}
]
...
}
1 => App\User {#2077 ▼
...
#relations: array:4 [▼
"roles" => Illuminate\Database\Eloquent\Collection {#2093 ▼
#items: []
}
]
...
}
]
}
as you can see in above output second user doesn't have any role and #items: [] is empty. i don't need to have this output structure and i want to have only which users have specific role, not all users with empty roles. second item of this collection shouldn't this output

Make your relationship conditional by using Laravel's whereHas:
$users = User::whereHas('roles', function ($query) {
$query->whereLabel('is-portal-manager');
})->with('roles')->get();
