Question

我在laravel分页中遇到问题。在laravel中，当我调用paginate()方法时，它将返回

{
   "total": 50,
   "per_page": 15,
   "current_page": 1,
   "last_page": 4,
   "first_page_url": "http://laravel.app?page=1",
   "last_page_url": "http://laravel.app?page=4",
   "next_page_url": "http://laravel.app?page=2",
   "prev_page_url": null,
   "path": "http://laravel.app",
   "from": 1,
   "to": 15,
   "data":[
        {
            // Result Object
        },
        {
            // Result Object
        }
   ]
}

这种类型的对象。我想要的是我想在一个变量中设置数据，例如$a，而在$b中设置其他所有值。

但是，当我向我的分页变量添加appends('data')时，它无法正常工作。谷歌搜索后没有找到解决方案。请帮我解决这个问题。

这是用户模型

<?php

namespace App;

use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Support\Facades\Auth;
use Illuminate\Database\Eloquent\SoftDeletes;

class User extends Authenticatable {

    use Notifiable;

    use SoftDeletes;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name', 'email', 'password', 'status', 'role_id',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];
}

我的控制器代码是

public function index() {

        $users = User::where('status', 1)->paginate(10);

return response()->json(
            [
                'error' => 0,
                'errorMsg' => '',
                'data' => [
                    'users' => $users->appends('data')->toArray(),
                ],
            ]
        );
}

我尝试了此代码

return response()->json(
                [
                    'error' => 0,
                    'errorMsg' => '',
                    'data' => [
                        'users' => $users->only($user['data'])->toArray(),
                        'users_pagination' => $users->except($user['data'])->toArray(),
                    ],
                ]
            );

在这种情况下，用户可以正常工作，但users_pagination无法正常工作。在这两个用户中，users_pagination返回相同的值

Answer 1

为什么不尝试迭代对象？下面的代码会将用户特定的数据附加到每个用户中。

public function index() {
  $users = User::where('status', 1)->paginate(10);
  foreach($users as $users){
    $users->data = 'your data here';
  }

  return response()->json([
      'error' => 0,
      'errorMsg' => '',
      'data' => [
        'users' => $users,
      ],
    ]
  );
}

如果要使用Laravel附加项，则必须按照document进行操作。

尝试

    $paginateData = User::where('status', 1)->paginate(10);

    $arrPaginateData = $paginateData->toArray();

    $users = $arrPaginateData['data'];

    unset($arrPaginateData['data']); //remove data from paginate array

    $pageInfo =  $arrPaginateData;

返回回复

    return response()->json(
        [
            'error' => 0,
            'errorMsg' => '',
            'data' => [
                'users' => $users,
                'users_pagination' => $pageInfo
            ],
        ]
    );

Laravel分页将数据追加到一个变量中，并将其他数据追加到另一个变量中
