php - 在 laravel 中使用自定义软删除列

Question

我知道如何在 laravel 中对模型使用软删除功能。像这样:

class Flight extends Model
{
    use SoftDeletes;

    protected $dates = ['deleted_at'];
}

但我想为该功能使用名为 sender_deleted_at 的自定义列，其中所有相关方法如 forceDelete 、 restore 、 withTrashed 等基于该列工作。

我写了this Question但是我找不到正确的答案。

我正在使用 Laravel 5.3。

SoftDeletes 特性使用此代码“删除”一行:

protected function runSoftDelete() {
        $query = $this->newQueryWithoutScopes()->where($this->getKeyName(), $this->getKey());
        $this->{$this->getDeletedAtColumn()} = $time = $this->freshTimestamp();
        $query->update([$this->getDeletedAtColumn() => $this->fromDateTime($time)]);
}

getDeletedAtColumn() 的主体是:

public function getDeletedAtColumn() {
    return defined('static::DELETED_AT') ? static::DELETED_AT : 'deleted_at';
}

因此你可以这样做:

class Flight extends Model
{
    use SoftDeletes;    
    protected $dates = ['my_deleted_at'];
    const DELETED_AT = 'my_deleted_at';
}
