Yii ActiveRecord-Relation保存不连接模型

Question

Yii的activerecord-relation-behavior扩展有问题。

我有一个主要的模式：User和子模型：UserPerson（一种型材）

这两个模型之间的关系是设置好的，模特的行为正在使用yiiext，但我仍然无法将它们连接起来。

在这种情况下$this是一个模型，它扩展了User模型，并呼吁RegistrationModel

$person = new \UserPerson(); 
$person->full_name = $this->name; 
$person->birthday = $this->birthday; 
$person->gender = $this->gender; 

$this->person = $person; 
$this->person->save(); 

这样，我应该能够运行：$this->save() 但我得到这个错误：

You can not save a record that has new related records!

我尝试了很多变化，但只有丑陋的无关联版本才起作用。 :(

$person->user_id = $this->id; 
//.. 
$person->save(); 

没有人有一个建议，这个问题

Answer 1

答案是在repository of the extension：

"You can not save a record that has new related records!"

You have assigned a record to a relation which has not been saved (it is not in the database yet). Since ActiveRecord Relation Behavior needs its primary key to save it to a relation table, this will not work. You have to call ->save() on all new records before saving the related record.

所以，你必须保存相关的模型，加上相关的元素和然后保存模型

$person = new \UserPerson(); 
$person->full_name = $this->name; 
$person->birthday = $this->birthday; 
$person->gender = $this->gender; 
$person->save(); 
//now $person has a primary key 

$this->person = $person; 
$this->person->save();
