In Laravel when I use the length aware pagination, let’s assume I was on the last page of the data set and I deleted all the records on that page, Laravel will return an empty data set for me since the page query param references the page number for a none existent offset even though there might still be other records available.

UserController.php:

...
$pager = AppModelsUser::paginate(10);

return view('user_list', concat($pager));

user_list.blade.php:

@foreach($pager->data() as $user)
   <div>
      <span>{{$user->name}}</span>  
      <a href="{{route ('user.destroy', $user->id)}}">Delete</a>
   </div>
@endforeach

In this case:

1. How do tell that there are no more records for the current offset/page.
2. How do I tell if the previous offset/page still contains active records.
3. How do I elegantly force Laravel to redirect to the previous page without compromising user experience?
