Question

我有以下代码：

$new_models = DB::transaction(function () use ($supplier, $address, $addressDetail) {            
        $new_supplier = $this->setNewSupplier($supplier);
        $new_address = $this->setNewAddress($address);           
        $new_addressDetail = $this->setNewAddressDetail($addressDetail,$new_address->id);           
        $this->syncSupplierAddress($new_supplier->id,$new_address->id);
        $this->updateControlAp($new_supplier->supplier_id);   
        return [$new_supplier, $new_address, $new_addressDetail];
    });

set方法基本上是在最后用save（）创建模型对象; 现在，如果第二个... nth失败，这完全正常，但如果第一个失败则不行。如果$this->setNewSupplier($supplier); 失败比我得到

"PDOException in Connection.php line 541:
There is no active transaction"

我在这里做错了吗？此外，如果我从供应商Connection.php中的catch中评论$this->rollBack();，它实际上给了我SQL错误。这里重要的一点是，只有在第一次save（）失败时才能使用

PS。我使用PostgreSQL而不是MySQL，但我不认为它是相关的

在Laravel中有不同的交易方式，另一种可能是：

...
$new_models = [];
try {
  DB::beginTransaction();

  $new_supplier = $this->setNewSupplier($supplier);
  $new_address = $this->setNewAddress($address);           
  $new_addressDetail = $this->setNewAddressDetail($addressDetail,$new_address->id);           
  $this->syncSupplierAddress($new_supplier->id,$new_address->id);
  $this->updateControlAp($new_supplier->supplier_id);   
  $new_models = [$new_supplier, $new_address, $new_addressDetail];

  DB::commit();
} catch(\Exception $e) {
   DB::rollback();
   // Handle Error
}
...

Laravel DB ::事务异常PDO没有活动事务
