laravel、mysql 回滚后事务无法正常工作

Question

我正在使用 laravel 5.8 同时在 4 个表中执行插入。当我提交不完整的表格时它会显示错误，然后当再次提交正确的数据时它会显示数据库错误

SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`matrimonial_db`.`personal_details`, CONSTRAINT `personal_details_ibfk_1` FOREIGN KEY (`site_user_id`) REFERENCES `siteuser` (`id`) ON DELETE NO ACTION ON UPDATE NO ACTION) (SQL: insert into `personal_details` (`site_user_id`, `updated_at`, `created_at`) values (148, 2020-04-29 05:16:53, 2020-04-29 05:16:53))

第一次填写表格时，它成功地在所有表格中插入数据，但再次尝试时，它会显示错误。这是一个代码

try
        {
            $connection = DB::connection('mysql');
            $connection->beginTransaction();
            $userData = session()->get('registeruser_data');
            $userData->user_type = 'v';
            $userData->save();

            $personal_details= new PersonalDetail;
            $personal_details->site_user_id =$userData->id;
            $personal_details->save();

            $personal_bio= new PersonalBio;
            $personal_bio->site_user_id =$userData->id;
            $personal_bio->save();


            $partner_details= new PartnerDetail;
            $partner_details->site_user_id =$userData->id;
            $partner_details->save();

            $personal_img= new PersonalImage;
            $personal_img->site_user_id =$userData->id;
            $personal_img->save();

            $connection->commit();
            session(['siteuser' => $userData->id]);
            return redirect('/edit/profile');
            // dd($charge);

        }
        catch(Exception $ex)
        {
            $connection->rollBack();
            return redirect::back()->withErrors(['stripe'=>$ex->getMessage()]);
        }

Answer 1

首先检查外键

$userData 是一个集合，因为你不是在寻找特定的用户，而是在保存整个 table registeruser_data，我建议你使用 eloquent 作为会更容易

您正在寻找这样的用户：

$user = yourModelUser::find($idUser);

或

$user = yourModelUser::where('id' $idUser)->where('type', 'v')->first();

然后：

$user->type = 'n';
$user->save();

如果您需要更多查询可以查看官方文档： https://laravel.com/docs/7.x/eloquent
