Laravel事务：如何提交一些查询而不是全部回滚？

Question

异常中止请求的事务块，以便回滚。但是现在每当出现异常时，都需要存储数据——异常的详细信息到table。中止请求时，insert/update 查询也会回滚。

\DB::transaction(function () use ($request) {
    try{
        // operations
    }catch(Exception $e){
        $exception_model = new ExceptionModel();
        $exception_model->user = $request->user_info;
        $exception_model->detail = $e;
        $exception_model->save();

        abort(Response::HTTP_BAD_REQUEST, 'Something went wrong');
    }
});

但由于它会自动回滚（即，laravel 事务关闭），异常模型更改也会回滚。怎么做到的？

Answer 1

您可以在闭包之外手动使用事务。这样您就可以将数据存储在 $exception_model:

    try{
        DB::beginTransaction(); //Initiate transaction
        // operations
        DB::commit(); //Commit transaction after all the operations
    }catch(Exception $e){
        DB::rollBack(); //Rollback if the exception occurs, but still save data  in your exception model
        $exception_model = new ExceptionModel();
        $exception_model->user = $request->user_info;
        $exception_model->detail = $e;
        $exception_model->save();

        abort(Response::HTTP_BAD_REQUEST, 'Something went wrong');
    }

将事务放在 try 块中应该可行：

use Exception;

try {
    \DB::transaction(function () use ($request) {
        // operations
    });
} catch (Exception $e) {
    $exception_model = new ExceptionModel();
    $exception_model->user = $request->user_info;
    $exception_model->detail = $e;
    $exception_model->save();

    abort(Response::HTTP_BAD_REQUEST, 'Something went wrong');
}
