Laravel响应ID在response为json时发生更改，但在转储数据时存在id

Question

我正在尝试在Laravel中使用ajax请求，该请求基于select2输入来搜索记录。现在，一旦获取数据，我将对其进行转换，仅用于加密ID。这是我获取记录并转换其ID进行加密的方式。

    public function autocompletePedigree($subdomain, $type = null)
    {

        $q = request()->get('q');

        $sex = NULL;
        if (!is_null($type)) {
            $sex = $this->sexesRepository->make()->where('name', $type)->first(['id'])->id;
        }

        $results = $this->dogsRepository->search($q, $sex);

        $results->getCollection()->transform(function ($value) {
            $value->id = encrypt($value->id);
            return $value;
        });

        return $results;
    }

现在结果包含一个狗的名字和ID，当我使用dd($results)时，ID被转换并正确了，这是一个示例

#attributes: array:2 [▼
  "id" => "eyJpdiI6IlN5YXdzT3hReEc2bnczRGM5YzV1eGc9PSIsInZhbHVlIjoiZ0NpaTRGWjNmS1ZEQjVZcGFZeWJRdz09IiwibWFjIjoiMThmNmQ5YmE5ZDI1MDg4OTZhMmExMTlmNzM0ZGU3ZDRhNzg0OGFhNzM2OTViYzVkN2QxZTUzMzMwMWY4ZDdhYiJ9"
  "text" => "Koffiewater Chicco"
]

但是当我使用return response()->json($results)切换到JSON时，它会返回此

"data":[
  {
    "id":0,
    "text":"Koffiewater Chicco"
  },
  {
    "id":0,
    "text":"Koffiewater Columbus"
  }

我不明白为什么将id变成0。这是某种JSON清理过程吗？有人可以帮我将加密的ID保留在JSON响应中吗？

更新：已添加模型

<?php
namespace BBAfrica\Clubs\Repositories\Dogs;

use DB;
use BBAfrica\Clubs\Extensions\Model;
use App\AuditTrail;

class Dogs extends Model {

    protected $table = 'dogs';

    /**
     * Properties that can be mass assigned
     *
     * @var array
     */

    protected $fillable = [
        'breeder_id',
        'dog_no',
        'dog_name',
        'dog_score',
        'dog_image',
        'sex_id',
        'ba_status_id',
        'added_by',
        'breed_id'
    ];

    public function sex() {
        return $this->hasOne('BBAfrica\Clubs\Repositories\Sexes\Sexes', 'id', 'sex_id');
    }

    public function ba_status() {
        return $this->hasOne('BBAfrica\Clubs\Repositories\BaStatuses\BaStatuses', 'id', 'ba_status_id');
    }

    public function added() {
        return $this->belongsTo('BBAfrica\Clubs\Repositories\User\User', 'added_by');
    }

    public function parents () {
        return $this->hasOne('BBAfrica\Clubs\Repositories\Parents\Parents', 'dog_id', 'dog_no');
    }

    public function breeder () {
        return $this->hasOne('BBAfrica\Clubs\Repositories\Breeders\Breeders', 'id', 'breeder_id');
    }

    public function clubDog () {
        return $this->hasOne('BBAfrica\Clubs\Repositories\ClubDogs\ClubDogs', 'id', 'dog_id');
    }

    public function audit(){
      return $this->morphOne(AuditTrail::class,'audit_trails');
    }

}

扩展模型

<?php namespace BBAfrica\Clubs\Extensions;


use BBAfrica\Extensions\Model as BBAfricaModel;
use Carbon\Carbon;

class Model extends BBAfricaModel {

    protected $hidden = array(
        'updated_at',
        'is_active',
        'ss_sync_id'
    );

    /**
     * List of all dates fields in database to create Carbon instances
     *
     * @return array
     */
    public function getDates() {
        return [
            'created_at',
            'updated_at',
            'session_start_date',
            'session_end_date',
            'term_start_date',
            'date_of_birth',

    }
}

        }

        return $this;
    }

Answer 1

经过一番挖掘后，我发现它已自动转换为整数，从而引起了一些混乱。因此，我通过将public $incrementing = false;添加到Dogs模型

解决了此问题

Answer 2

对于其他好奇于此的人（如我）：

他正在更改模型主键的类型。当他（或在这种情况下为JsonResponse）在模型上调用toJson()时，它将尝试将主键（已手动更改为string）转换回其原始值（int）。发生这种情况是因为主键实际上是模型的added to the $casts property：

$casts

...并且当模型被序列化到数组（随后是JSON）时，属性被强制转换。
