User Roles

Hi there, I'm trying to get simple user roles working. I just want every user to have a role, for example Visitor or Admin.

//User.php 
 public function roles()
    {
        return $this->hasOne(Role::class);
    }

//Role.php
public function users()
    {
        return $this->belongsToMany(User::class);
    }  

//User table migration
  $table->integer('role_id');
            $table->foreign('role_id')->references('id')->on('roles');

I'm just trying to accoplish to get that relationship working, so that i can do this in the html:

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

Instead of doing:

@foreach($users as $user)
	{{$user->role_id}}
@endforeach
