Laravel, use pagination Method Illuminate\Database\Eloquent\Collection::render does not exist

Question

I'm trying to use paginate but it doesn't work, without paginate all are fine but when I use it I get this error Method Illuminate\Database\Eloquent\Collection::links does not exist

Controller:

$userorders=Userorder::where('user_id', $user_id)
    ->with('storeinfo')
    ->with('product')
    ->paginate(15)
    ->groupBy('order_number');

view:

@if( count($userorders) > 0 )
    {!! $userorders->links() !!}
@endif 

Answer 1

Because links() is a method of LengthAwarePaginator , instead groupBy will return a Collection , so the only way you can have your UserOrder grouped by its order_number is to switch the order of the calls, to this one

$builder= Userorder::where('user_id',$user_id)->with('storeinfo')->with('product');
$userOrdersPagination=$builder->paginate(15);
$userorders=$userOrdersPagination->groupBy('order_number')

And then you have to pass to the view also $userOrdersPagination and use that to generate the links
