嗨，我整天都在努力让这个分页工作。 此处示例：https://sourcemod.market/scripts?search=&game_id=&category_id=&sort=best_rated&added=&price_min=0&price_max=100

如您所见，第一页我得到了 3 个带有评级的产品，我需要进入第二页才能得到其他产品..

我在发布前尝试了很多东西，WhereHas、Eager loading、With('') 和搜索答案。

好的，我换了一个

 */
public function index(Request $request)
{   
    $scripts = ScriptModel::select(
        '*',

如果有人有更轻的东西:) 请告诉我
