Cakephp 1.3 到 2.0 的转换
我正在尝试将 Cake 1.3 应用程序更新到 2.0。在某些模型方法中，我加载会话和电子邮件组件，如下所示：
App::uses('SessionComponent', 'Controller/Component');
App::uses('EmailComponent', 'Controller/Component');
$Session = new SessionComponent();
$Email = new EmailComponent();
但是，当我加载这些页面时，我收到此错误：
Warning (4096): Argument 1 passed to Component::__construct() must be an instance of ComponentCollection, none given, called in /Users/username/Sites/cake2app/app/Model/User.php on line 183 and defined [CORE/Cake/Controller/Component.php, line 77]
Notice (8): Undefined variable: collection [CORE/Cake/Controller/Component.php, line 78]
What's theproper way to load and use Components in Cake 2.0 like we can with Cake 1.3?
I'm trying to update my Cake 1.3 app to 2.0. In some of the Model methods I'm loading the Session and Email components like this:
App::uses('SessionComponent', 'Controller/Component');
App::uses('EmailComponent', 'Controller/Component');
$Session = new SessionComponent();
$Email = new EmailComponent();
However when I load those pages I get this error:
Warning (4096): Argument 1 passed to Component::__construct() must be an instance of ComponentCollection, none given, called in /Users/username/Sites/cake2app/app/Model/User.php on line 183 and defined [CORE/Cake/Controller/Component.php, line 77]
Notice (8): Undefined variable: collection [CORE/Cake/Controller/Component.php, line 78]
What's the proper way to load and use Components in Cake 2.0 like we could with Cake 1.3?

EmailComponent已被CakeEmail类取代，请参阅 http://book.cakephp.org/2.0/en/core-utility-libraries/email.html 了解有关如何使用此类的更多信息。当您想要访问模型中的会话时，您必须使用
CakeSession类，而不是SessionComponent。您可以包含此类：不需要实例化此类。
The
EmailComponenthas been replaced by theCakeEmailclass, see http://book.cakephp.org/2.0/en/core-utility-libraries/email.html for more information about how this class is used.And instead of the
SessionComponentyou have to use theCakeSessionclass when you want to access the session in your model. You can include this class with:It is not necessary to instantiate this class.
