在yii2中,我如何将多个相关记录保存到db中,成为单个保存调用和单个事务。
我有两个表:
User - id, name
UserAddress - id , user_id , city
用户表与用户地址表具有一对多关系
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();
在用户上调用save时,也应保存user_id也设置为user.id的用户和用户地址
最佳答案
// 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();
}
