php - Laravel get model by hasManyThrough -

i have 3 classes - user, business , businessroleuser (and respective tables)

(user) id | first_name | last_name

(business) business_id | business_name

(business_role_user) user_id | business_id | role_id

i have combined role of user in same table multiple roles user's can have towards business i.e. admin, staff, etc. in business_roles table.

i access business model through logged in user update fields i.e.

$business = user::find(auth::id())->business();  $business->fill(input::all()); $business->save();

at present in user class have following (really each user associated 1 business):

public function business()     {         return $this->hasmanythrough('app\business', 'app\businessroleuser', 'business_id', 'user_id');     }

but if simple dd(user::find(auth::id())->business->business_name);

it throws error

business name undefined

it's not finding business model associated user. i've looked @ many examples of hasmanythrough failing work, appreciate help!

(note user table uses id other tables use user_id, not sure if causing issue)
