Answer 1

In controller:
public function index(){
$fathers = Father::all();
return view('admin.eleves', compact('fathers');
}
In blade file:
#forelse($fathers as $father)
<td class="numeric" data-title="id-parent" >{{$father->id}}</td>
#empty
#endforelse

Answer 2

Post your controller code. The error is that blade does not recognize a father variable so something on your backend has gone wrong. Should look something like this.
class YourController extends Controller
{
public function example()
{
$father = YourFatherModel::all();
return view('app.main', compact('father'));
}
}

Answer 3

You might have the variable spelling wrong or you haven't sent the variable to the blade file. Try one of these
$father=Father::all();
return view('admin.eleves', compact('father'));
OR:
$data['father']=Father::all();
return view('admin.eleves', $data);
