拉拉维尔。 我无法显示关系中的数据

Question

i have strange problem. dd(), It shows me that I got to the data, but i cant display single record from table.

I want to get to the name of my role but i get this error :

Property [name] does not exist on this collection instance

Model - User

public function roles()
{
    return $this->belongsToMany(Role::class);
}

Controller

$users = User::with('roles')->get();
return view('pages.user', compact('users'));

View

@foreach($users as $user)
        {{$user->id}}
        <br>
        {{$user->name}}
        <br>
        {{$user->email}}
        <br>
        {{$user->roles->name}}  //this not working
        <br>
        <br>
    @endforeach

When Im using {{$user->roles}} I get

{"id":1,"name":"Admin","description":"this is admin","pivot":{"user_id":2,"role_id":1}}]

what Im doing wrong? Thx for help.

Answer 1

$user->roles return a collection as it's defined as a belongsToMany relation and you cannot access name from it.

Either you have to iterate through the collection or get the first one.

$user->roles->first()->name

or

@foreach ($user->roles as $role)
    {{ $role->name }}
@endforeach

Answer 2

$user->roles is a collection of elements, you are trying to get a property on a list of elements.

You could use implode for example to display all roles comma seperated.

{{ $user->roles->implode('name', ', ') }}
