Question

场景：          学生->父母，          学生儿童班
           父母：学生
           子：标记                          地址
           大孩子主要地址                            辅助地址

   We are using the Cascade Soft-Delete for the above scenario with the code below :

这里发生了多次删除，需要建议以了解是否必须为级联删除添加事务管理。

 use Illuminate\Database\Eloquent\SoftDeletes;

 class Student extends Model
  {
   use SoftDeletes;

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

    static::deleting(function ($student) {
        foreach ([
            'address',
            'mark'
        ] as $relation) {
            foreach ($student->{$relation} as $item) {
                $item->delete();
            }
        }
    });
  }

 public function address()
   {
    return $this->hasMany(StudentAddress::class, 'student');
    }

  public function mark()
   {
    return $this->hasMany(Marks::class, 'mark_detail');
   }
 }

要在Laravel中添加交易，请检查以下代码

\DB::transaction(function () {

DB::beginTransaction();
     Your queried goes here
DB::commit();
