Yii2 在单个事务中的单个保存调用中保存相关记录 [英] Yii2 save related records in single save call in single transaction

问题描述

在 yii2 中，如何将多个相关记录保存到 db 中，以便进行单个保存调用和单个事务.我有两张桌子:

In yii2 how can i save multiple related records into db into single save call and single transaction. I have two tables:

User - id, name
UserAddress - id , user_id , city

User 表和 UserAdress 表有一对多的关系

User table has one to many relation to UserAdress table

我想做的是:

UserAddress ua = new UserAddress();
ua.city = "fff"

User u = new User();
u.name = "test";
u.userAddress = new Array(ua);
u.save();

调用保存用户应该保存用户和用户地址，并将 user_id 设置为 user.id

calling save on user should save user and useraddress with user_id set to user.id as well

推荐答案

 // You need create hasMany relation 'userAddress' (look guide relations)

$transaction = Yii::$app->db->beginTransaction();

try {

    $user = new User();
    $user->name = 'Name';
    $user->save();

    $ua = new UserAddress();
    $ua->city = 'City';

    $user->link('userAddress', $ua); // <-- it creates new record in UserAddress table with ua.user_id = user.id

    $transaction->commit();

} catch (Exception $e) {

    $transaction->rollBack();

}
