我遇到问题，我在用户表中有一个角色列，所以当我在做

  $ user-> role-> role_name 
 / pre> 

它正在获取角色列而不是关系。
 
I have two tables :
User ->
 id : 
 name : 
 role_id : ->refernces('id')->on('roles');

Roles ->
 id :
 role_name :
 access :
I am trying to access roles details from user.

My user model has :
public function role(){
        return $this->belongsTo('App\Role');
    }
My role model has :
public function user(){
      return $this->hasMany('App\User');
  }
When I try to do following :
$user = User::find(1);

        $details = [
            'name' => $user->first_name,
            'role' => $user->role->role_name

        ];
I get error :
Trying to get property of non-object
My roles table contains access columns containing array of permissions to different routes. So my user will have only one role. While a role can have multiple users.
How to do that?
I got the problem, i was having a role column in user table, so when i was doing 
$user->role->role_name
it was fetching role column instead of relationship.
