Question

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

我正在使用SQLServer，这些字段的格式为datetime，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,

我为$ cast尝试了所有日期格式，但没有用，我尝试设置$ dateFormat = Ymd H：i：s或Ymd H：i：s.000或Ymd H：i：su或Ymd H：i：sv无效。

//My Model

        'end_date' => 'datetime:Y-m-d H:i:s',
        'draw_date' => 'datetime:Y-m-d H:i:s',
    ];

        parent::boot();

        static::creating(function ($quickQuiz) {

            $quickQuiz->uuid = Str::uuid();
            $quickQuiz->status_id = Status::pendent();

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

        });

        static::updating(function ($quickQuiz) {
            $quickQuiz->updated_user_id = auth()->user()->id;

        });
    }

    public function questions()

        return $this->hasMany(QuickQuizQuestion::class);
    }

    public function createdUser()
    {
        return $this->belongsTo(User::class, 'created_user_id', 'id');
    }

    public function updatedUser()

Answer 1

尝试像这样将日期强制转换为'Y-m-d H：i：s.u0'：

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。尝试在您的模型中定义 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;
}
