Laravel DB交易上下文可在称为功能上获得

我发现，用于在Laravel中使用DB ::交易，与ORM结合使用，我们需要运行类似的内容：

DB::transaction(function() {
      //
   Model::create($something);
});

我的问题是：如果我需要从封闭式内部调用其他功能，该功能运行其他创建方法，则“交易”环境中会有或在外面？

DB::transaction(function() {
      //
   ModelX::create($something);
   $this->somefunction($data);
});

private function somefunction($data){

    ModelY::create($data) <----this create is in the transaction or do I need a new one for having rollback in case of errros?

}

I have found that for using DB::transaction in Laravel, in combination with the ORM, we need to run something like:

DB::transaction(function() {
      //
   Model::create($something);
});

My question is:
If i need to call other function from inside the closure, that runs other creation method, there will be in the "transaction" enviroment or is it outside?

DB::transaction(function() {
      //
   ModelX::create($something);
   $this->somefunction($data);
});

private function somefunction($data){

    ModelY::create($data) <----this create is in the transaction or do I need a new one for having rollback in case of errros?

}

请记住，您的代码可以使用不会返回重定向的任何其他功能/方法。这将跳过提交（）或回滚（）。一旦开始transAction（）启动，它必须以commit（）或滚动（）结尾。

    DB::beginTransaction();
    try {
       /* your code */
       /* you can also use DB::commit(); at the end of TRY code like this */
    } catch (\Exception $ex) {
       DB::rollback();
       /* handle error */
       /* use return after rollback() */
    }
    DB::commit();

    /* use return after commit(); */

Remember that your code can use any additional functions/methods that will not return redirect. This will skip commit() or rollback(). Once the beginTransaction() started it has to end with commit() or rollback().

    DB::beginTransaction();
    try {
       /* your code */
       /* you can also use DB::commit(); at the end of TRY code like this */
    } catch (\Exception $ex) {
       DB::rollback();
       /* handle error */
       /* use return after rollback() */
    }
    DB::commit();

    /* use return after commit(); */

经过几次测试，我可以说，即使您在另一个功能内有一个创建方法，并且在主要或在功能中抛出了异常 - 回滚并提交脂肪都没有问题！
我希望更多！！！！

这是我测试的代码：

   DB::beginTransaction();
        try {
            $this->pippo();
        } catch (\Exception $ex) {
            DB::rollback();
        }
   DB::commit();

public function pippo(){
    $type=Cga_type::create(['name'=>'vvvv','description'=>'yyy']);
    throw new Exception('error');

}

如果我评论交易功能，则记录写在DB上，没有其他否则！！！

after several test i can tell that no closure is needed for model too, even if you have a create method inside another function, and exception is throwed -in the main or in the function- no problem with the rollback and commit steatment!
Well much more of that i was hoping!!!!

This is the code I tested:

   DB::beginTransaction();
        try {
            $this->pippo();
        } catch (\Exception $ex) {
            DB::rollback();
        }
   DB::commit();

public function pippo(){
    $type=Cga_type::create(['name'=>'vvvv','description'=>'yyy']);
    throw new Exception('error');

}

If I comment the transactions functions the record is written on the db, no otherwise!!!
