php - Laravel Eloquent Query Buliding -

i have 4 tables , giving table structure here

1. user_work['id', 'user_id', 'work_id']
2. work_sectors['id', 'name', 'status']
3. works['id', 'work_sector_id', 'work_type_id', 'work_duration_id', 'name']
4. users['id', ...]

and models are

class user extends eloquent implements userinterface, remindableinterface  {   use usertrait, remindabletrait;   protected $table = 'users';   public function work()   {        return $this->belongstomany('work', 'user_work');   } }  class work extends \eloquent { protected $fillable = []; protected $table_name = 'works'; public $timestamps = false;  public function user() {     return $this->belongstomany('user', 'user_work'); }  public function sector() {     return $this->belongsto('worksector', 'work_sector_id'); } } 

in controller have written code

$user = user::with('language')->with('work')->find($userid);
