在PHP 7.1 、Yii 2 中，AR 活动记录事务，需要同时操作多个模型的实现
1、在PHP 7.1 、Yii 2 中，AR 活动记录事务，需要同时操作多个模型的实现，如图1
$transaction = $this->db->beginTransaction();
try {
if (!$this->save()) {
throw new ServerErrorHttpException('Failed to create the object for unknown reason.');
}
/* 创建MySQL模型(内容详情) */
$contentDetail = new ContentDetail();
$contentDetail->tenantid = $this->tenantid;
$contentDetail->content_audit_id = $this->id;
$contentDetail->content = $this->content;
if (!$contentDetail->save()) {
throw new ServerErrorHttpException('Failed to create the object for unknown reason.');
}
$transaction->commit();
} catch(\Throwable $e) {
$transaction->rollBack();
throw $e;
}

2、测试事务是否支持，特意让$this->save()操作失败、让$contentDetail->save()操作成功，响应如下，如图2

3、查看数据库，此时$this、$contentDetail皆未执行成功，如图3

4、测试事务是否支持，特意让$this->save()操作成功、让$contentDetail->save()操作失败，响应如下，如图4
图4

"name": "Internal Server Error",
"message": "Failed to create the object for unknown reason.",
"code": 0,
"status": 500,
"type": "yii\\web\\ServerErrorHttpException"
}

8、可以继续新增模型
$transaction = $this->db->beginTransaction();
try {
if (!$this->save()) {
throw new ServerErrorHttpException(Yii::t('error', '20032'), 20032);
}
/* 创建MySQL模型(内容详情) */
$contentDetail = new ContentDetail();
$contentDetail->tenantid = $this->tenantid;
$contentDetail->content_audit_id = $this->id;
$contentDetail->content = $this->content;
if (!$contentDetail->save()) {
throw new ServerErrorHttpException(Yii::t('error', '20033'), 20033);
}
/* 创建MySQL模型(审核记录) */
$auditLog = new AuditLog();
$auditLog->tenantid = $this->tenantid;
$auditLog->content_audit_id = $this->id;
$auditLog->step = self::AUDIT_PROCESS_STEP_AIR;
$auditLog->operation_user = '';
$auditLog->operation_user_id = 0;
$auditLog->cause = '';
$auditLog->status = self::STATUS_ACTIVE;
$auditLog->created_at = $time;
if (!$auditLog->save()) {
throw new ServerErrorHttpException(Yii::t('error', '20034'), 20034);
}
$transaction->commit();
} catch(\Throwable $e) {
$transaction->rollBack();
throw $e;
}
