如何在分页资源上获取模型的属性

问题描述

我想使用Resource在流明上显示分页资源.

I want to display paginate resource on lumen using Resource.

我需要如下所示的json结果:

I need this shown as below json result:

{
  "meta": {
    "count": 10,
    "total": 100
  },
  "links": {
    "first": "http://localhost/page[limit]=10&page[offset]=0",
    "last": "http://localhost/page[limit]=10&page[offset]=10",
    "next": "http://localhost/page[limit]=10&page[offset]=10",
    "prev": "null"
  },
  "data": [
    {
      "type": "items",
      "id": "1"
    }
  ]
}

这是我的控制器:

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\Item\Eloquent\ItemModel as ItemModel;
use App\Http\Resources\ItemsResource;

public function completeitems(Request $request)
{
    $res    = ItemModel::paginate();
    return new ItemsResource($res);
}
?>

这是我的 ItemResource :

<?php
namespace App\Http\Resources;
use Illuminate\Http\Resources\Json\Resource;

class ItemsResource extends Resource
{
    /**
     * Transform the resource into an array.
     *
     * @param  \Illuminate\Http\Request
     *
     * @return array
     */
    public function toArray($request)
    {
        return [
            'type'          => 'items',
            'id'            => $this->id
        ];
    }
}

从我的代码中得出的结果是:

From my code the result is:

Undefined property: Illuminate\Pagination\LengthAwarePaginator::$id

我已经尝试了很多次，并在Google上搜索了错误但有点困惑.怎么解决呢?谢谢.

I have tried this many time and google the error but a bit confuse.How to solve this? Thank you.

推荐答案

使用collection()方法返回多个模型:

Use the collection() method to return multiple models:

public function completeitems(Request $request)
{
    $res    = ItemModel::paginate();
    return ItemsResource::collection($res);
}
