Question

我的模型的日期声明为Carbon

public $dates = array('created_at', 'submitted_at');

当我尝试使用->toArray()将模型转换为数组或创建json响应时，我收到错误：

如果我删除了DateMutator，一切顺利，但我想保留它，因为检索到的MSSQL日期并不是真正的用户友好。

我该如何解决这个问题？

Answer 1

我遇到了同样的问题，我只找到了解决方法。似乎toArray函数调用以下内容：

Carbon\Carbon::createFromFormat('Y-m-d H:i:s.000', ...

在您的版本和我的版本中：

Carbon\Carbon::createFromFormat('Y-m-d H:i:s', ...

并且在某种程度上并非所有请求的数据（年/月......分钟/秒）都在对象中提供。

所以我所做的是在模型事件中，将模型带到或存储到数据库中，我手动修复日期，假设其余代码没有提供＆＃34;无效＆＃34;这些日期的值。当然，如果在某些时候为这些日期提供无效值并在保存到数据库之前调用toArray方法，则问题仍然存在。

public static function boot()
{
    parent::boot();

    static::saving(function($record){
        if (empty($record->the_date_attribute)) {
            // Perhaps set a default value here
        } else {
            if($record->the_date_attribute instanceof \Carbon\Carbon)
                $record->the_date_attribute->setTime(0,0,0);
        }
     }
    static::restored(function($record){
        if (empty($record->the_date_attribute)) {
            // Perhaps set a default value here
        } else {
            if($record->the_date_attribute instanceof \Carbon\Carbon)
                $record->the_date_attribute->setTime(0,0,0);
        }
     }
}

在我的情况下，我将时间设置为0，因为在我的数据库中，该字段是日期类型。另一种可能的解决方法是覆盖toArray方法并为其提供额外的数据，但我更喜欢事件，因为DB的数据与我需要的值一起存储。

在您的情况下，解决方案可能更简单。也许你提供时间信息，但你没有提供秒......？

我通过在使用SqlServer

的每个模型中添加微秒来格式化定义来解决

protected $dateFormat = 'Y-m-d H:i:s.u';

我想知道是否有办法将其配置为每个模型的默认值
