在laravel雄辩的结果中添加额外的关键点

检查这是否有效。虽然我没有尝试过,但根据文档,我们可以添加访问器和变异器。但它会改变你对模型的每一个反应。

// Your Model
class Race extends Model
{
    {...}
    protected $appends = ['period'];
    // accessor
    public function getPeriodAttribute($value)
    {  
        $this->attributes['period'] = (object)[];
        $this->attributes['period']['raceStart'] = $this->attributes['raceStart'];
        $this->attributes['period']['raceEnd'] = $this->attributes['raceEnd'];
        unset($this->attributes['raceStart']); = $value;
        unset($this->attributes['raceEnd']);
        return $this->attributes['period'];
    }
}

$race->period 将给出 raceStart 和 raceEnd 价值

否则,另一个选项是在查询后,执行 map

{...}
->map(function($data) {
    $data->period = (object)[];
    $data->period['raceStart'] = $data->raceStart;
    $data->period['raceEnd'] = $data->raceEnd;
    unset($data->raceStart);
    unset($data->raceEnd);
    return $data;
});

使用QueryBuilder

$races = DB::table('races')->get();

$races = array_map(function ($data) {
    $data->period = (object)[
        "raceStart" => $data->raceStart,
        "raceEnd" => $data->raceEnd
    ];
    unset($data->raceStart);
    unset($data->raceEnd);
    return $data;
}, $races->data);
