保存与Yii有很多关系的模型

Question

我有3个这样的表：用户（ID，名称）|教程（ID，Tutcontent）| UserTutorial（ID，IDUser，IDTutorial）。我使用此代码来保存模型

    $user = User::model()->findByPk(1);
    $tutorial = Tutorial::model()->findByPk(1);
    $userTutorial = new UserTutorial;
    $userTutorial->IDUser = $user->ID;
    $userTutorial->IDTutorial = $tutorial->ID;
    $userTutorial->save();

它不会在mydatabase中保存新记录

Answer 1

这是您的任务的一个非常有用的扩展：CAdvancedArBehavior
不要忘记正确定义模型的关系：A great tutorial about relations

Answer 2

试试这个..

    $user = User::model()->findByPk(1);
    $tutorial = Tutorial::model()->findByPk(1);
    $userTutorial = new UserTutorial;
    $userTutorial->IDUser = $user->ID;
    $userTutorial->IDTutorial = $tutorial->ID;
    $userTutorial->save(false);

Answer 3

$user = User::model()->findByPk(1);
$tutorial = Tutorial::model()->findAll("id=2");     
$user->**RELATION_ALIAS** = $tutorial;
$user->save();
