TP-ORM中使用分页时需要自定义分页的html,tp框架中通过provider.php配置中更换分页驱动,webman中怎么更换?

\think\Paginator::maker('app\common\Bootstrap');

    \think\Paginator::maker(function ($items, $listRows, $currentPage, $total, $simple, $options){
    return new \app\index\Bootstrap($items, $listRows, $currentPage, $total, $simple, $options);
    });

    在调用分页paginate方法前这样设置可以实现,可不可类似tp那样,做一下类的绑定就能相互替换这样的?

    要么等thinkorm更新分页参数中提供替换参数,要么就改 webman,在自定义函数文件 实现一个model,其中添加一下这段代码

    好的,谢谢

新建一个自定义查询类

<?php

namespace App\model;

use extend\tools\BearPage;
use think\db\Query;

class MyQuery extends Query
{
    public function pages($params = [])
    {
        $total = $this->count();
        $list = $this->page(get_per_page(), get_per_limit())->select()->toArray();
        $page = BearPage::getPageHtml(get_per_page(), ceil($total / get_per_limit()), $total, request()->path(), array_merge(request()->get(), $params));
        return ['list' => $list, 'page' => $page];
    }
}

在thinkorm.php文件中添加
