works like a charm!

$results = $mapHelpers->haversine(new Place(), $user->place->lat, $user->place->lng, 1000, 'kilometers', ['places.*']);

However I would like to know how to use this if I want to get the "nearest users" and the user table itself does not contain lat/lng values but instead there is a relation between User and Place on place_id field

How would I use this with such a relation in place?

How can I use paginate()

How can I use paginate()

change the ->get() for ->paginate(15) it should works
