laravel - DateTime::__construct(): 无法解析位置 0 (1) 处的时间字符串 (16/07/2020):意外字符

Question

在我的 Laravel 5.8 应用程序中，我有:config/app.php

'date_format' => 'd/m/Y',
'date_format_js' => 'dd/mm/yy',

模型

use Carbon\Carbon;

class HrHolidayDate extends Model
{
    protected $table = 'hr_holiday_dates';

    protected $fillable = [
        'holiday_name',
        'holiday_date',

    ];

    protected $dates = [
        'holiday_date'
    ];


    protected $casts = [];


    public function setHolidayDateAttribute($input)
    {
        $this->attributes['holiday_date'] =
            Carbon::createFromFormat(config('app.date_format'), $input)->format('Y-m-d');
    }


    public function getHolidayDateAttribute($input)
    {
        return Carbon::createFromFormat('Y-m-d', $input)
            ->format(config('app.date_format'));
    }
}

我尝试在 Blae View 中对其进行格式化，如下所示: view

@foreach($holidays as $key => $holiday)
    <td>
        {{Carbon\Carbon::parse($holiday->holiday_date)->format('d-m-Y') ?? '' }}
    </td>
@endforeach

当我想渲染 View Blade 时，出现此错误:

[2020-07-15 11:57:56] production.ERROR: DateTime::__construct(): Failed to parse time string (16/07/2020) at position 0 (1): Unexpected character (View: C:\xampp\htdocs\laravelapp\resources\views\hr\holiday_dates\index.blade.php) {"userId":466,"exception":"[object] (ErrorException(code: 0): DateTime::__construct(): Failed to parse time string (16/07/2020) at position 0 (1): Unexpected character (View: C:\xampp\htdocs\laravelapp

esbot\carbon\src\Carbon\Traits\Creator.php:81)[stacktrace]

我该如何解决？
谢谢

因为Carbon不懂d/m/Y格式开箱即用。如果你使用斜杠，它应该是 mm/dd/yyyy在这种情况下。 d/m/Y不是官方日期格式。
您可以使用 :

{{ Carbon\Carbon::createFromFormat('d/m/Y', $holiday->holiday_date)->format('d-m-Y') }}
