yii2 高级模板扩展用户模型并且没有保存数据

Question

我最近刚刚下载了 yii2 高级模板，并在前端模块中创建了新模型，像这样在“common/models”中扩展用户

class UsUser extends User
{

}

class SignupForm extends Model
{      

/**
 * Signs user up.
 *
 * @return User|null the saved model or null if saving fails
 */
public function signup()
{
    if ($this->validate()) {
        $user = new UsUser();
        $user->username = $this->username;
        $user->email = $this->email;
        $user->setPassword($this->password);
        $user->generateAuthKey();
        $user->save();
        return $user;
    }

    return null;
}

当我注册时，没有错误，只是被重定向到主页，但没有数据插入到数据库中。我没有在我的模型（User 或 UsUser）中使用由 Tal V. 指定的公共属性（Yii2 active record model not saving data）。所以在 UsUser 中只有 @property 注释。

也许我做错了，或者还有其他需要注意的地方，有人可以帮忙指出吗？非常感谢。

    /**
     * Signs user up.
     *
     * @return User|null the saved model or null if saving fails
     */
    public function signup()
    {
        if ($this->validate())
        {
            $user           = new UsUser();
            $user->username = $this->username;
            $user->email    = $this->email;
            $user->setPassword($this->password);
            $user->generateAuthKey();
            //IF UsUser MODEL IS VALID THEN SAVE DATA
            if ($user->validate())
            {
                $user->save(false);
                return $user;
            }
            //IF UsUser MODEL IS NOT VALID THEN PRINT THE ERRORS.SO YOU CAN CHECK WHAT ARE THE ERRORS IN MODEL
            else
            {
                echo "<pre>";
                print_r($user->getErrors());
                echo "</pre>";
            }
        }
    }

}
