            "price": 3000,
            "user_id": "2"
            "pivot": {
                "user_id": 44,
                "subscription_package_id": 1,
                "subscription_status": "on_free_trial",
                "expires_on": null,
                "id": 9
            },
            "courses": [
                {

$user=User::with(['studentDetails','subscriptionsStatus.courses'])
                         ->whereHas('subscriptionsStatus', function($query) use($filter){
                             $query->wherePivot('subscription_status','=',$filter);
                         })
                            ->withPagination($offset,$perPage)
                            ->get()
                            ->sortBy('first_name')->values();
