You need to call ->paginate() on your DB query or Eloquent Query https://laravel.com/docs/10.x/pagination

You should call paginate method to retrieve the records from your route handler or controller.

For example in your controller you are retriving the $inventory data like this:

$inventory = Inventory::all();

or

$inventory = Inventory::query()->get();

This should be changed to something like this:

$inventory = Inventory::query()->paginate();

You will get the access to the links method only if you are fetching data using paginate or simplePaginate method.

See more details here: https://laravel.com/docs/10.x/pagination#paginating-eloquent-r...

How are you retrieving the data for the $inventory variable?

Your database query or Eloquent Query needs to be paginated; see https://laravel.com/docs/10.x/pagination
