Laravel DB ::交易例外PDO沒有活動事務

Question

我有以下代碼：

$new_models = DB::transaction(function() use ($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]; 
    }); 

設定方法基本上創建模型與保存（）結尾對象; 現在，如果第二個...第n個失敗，這工作得很好，但如果第一個失敗，則不會。 如果$this->setNewSupplier($supplier); 失敗比我得到

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

難道我做錯了什麼嗎？另外，如果我從供應商Connection.php中捕獲的$this->rollBack();發表評論，它實際上給了我SQL錯誤。這裏的重要部分是，僅當首次保存（）失敗時纔會工作。

PS。我使用PostgreSQL的不是MySQL，但我不認爲它相關

有不同的方式，使交易Laravel，另外一個可能是這樣的：

... 
$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 
} 
...
