Laravel Nova - 保存新寄存器时数据丢失

Question

我的模型中有一些日期时间字段，当我尝试保存新寄存器时，工作正常，但是当我为日期设置 $casts 属性时（因为 laravel nova 需要它），我可以保存新寄存器，显示在数据库中，但返回下面的错误并且不重定向到索引页面。

我使用的是 SQLServer，字段是日期时间格式，例如“Y-m-d H:i:s.000”

"message": "Data missing",
    "exception": "InvalidArgumentException",
    "file": "/var/www/vendor/nesbot/carbon/src/Carbon/Traits/Creator.php",
    "line": 537,

我尝试了各种日期格式 $cast 并且不起作用，我尝试将 $dateFormat 设置为 "Ymd H:i:s" 或 "Ymd H:i:s.000" 或 "Ymd H:i:su" 或 "Ymd H: i:sv" 并且不起作用。

            $quickQuiz->updated_user_id = auth()->user()->id;

        });

        static::updating(function ($quickQuiz) {

Answer 1

尝试将日期转换为 'Y-m-d H:i:s.u0'，如下所示：

protected $casts = [
   'start_date' => 'datetime:Y-m-d H:i:s.u0',
   'end_date' => 'datetime:Y-m-d H:i:s.u0',
   'draw_date' => 'datetime:Y-m-d H:i:s.u0',
];

我在使用 SQLServer 时遇到了同样的问题。 尝试在你的模型中定义mutators for these attributes

/**
 * @var string
 */
protected $dateFormat = 'Y-m-d H:i:s.v';

/**
 * @param $value
 */
public function setStartDateAttribute($value)
{
    $this->attributes['start_date'] = null !== $value ? date($this->dateFormat, strtotime($value)) : null;
}

/**
 * @param $value
 */
public function setEndDateAttribute($value)
{
    $this->attributes['end_date'] = null !== $value ? date($this->dateFormat, strtotime($value)) : null;
}

/**
 * @param $value
 */
public function setDrawDateAttribute($value)
{
    $this->attributes['draw_date'] = null !== $value ? date($this->dateFormat, strtotime($value)) : null;
}
