Laravel-admin 数据来自外部 API

背景： 因为laravel-admin 文档缺少，同事又问了起来；所以在此做一个记录，希望能帮助更多的phper

<?php

namespace App\Models\Movie;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Pagination\LengthAwarePaginator;
use Illuminate\Support\Facades\Request;

class InTheater extends Model
{
   // 必须加上的
   public static function with($relations)
    {
        return new static;
    }

    public function paginate()
    {
        $perPage = Request::get('per_page', 10);

        $page = Request::get('page', 1);

        $start = ($page-1)*$perPage;

        $data = file_get_contents("https://api.douban.com/v2/movie/in_theaters?city=上海&start=$start&count=$perPage");

        $data = json_decode($data, true);

        extract($data);

        $movies = static::hydrate($subjects);

        $paginator = new LengthAwarePaginator($movies, $total, $perPage);

        $paginator->setPath(url()->current());

        return $paginator;
    }

    // 覆盖`orderBy`来收集排序的字段和方向
    public function orderBy($column, $direction = 'asc')
    {

    }

    // 覆盖`where`来收集筛选的字段和条件
    public function where($column, $operator = null, $value = null, $boolean = 'and')
    {

    }

    ...
}

调用 paginate 方法进行覆盖

   protected function grid()
    {
       $grid->paginate();
   }
