如何更正查找（“id=$view”）；用cakephp？

我从cake的旧版本中学习cakephp，因此一些代码需要更新我有一个控制器，它将数据传递到视图或布局这里是控制器：

BlogController.php

<?php
class BlogController extends AppController {

  var $name = 'Blog';
  var $uses = array('Blog');
  // Used when indexing the page (http://yourdomain.com/blog/)
function index($view = null) {
    // What to do if a view is set
    if (isset($view))
    {
      //problem is here
      $this->set('article', $this->Blog->find("id = $view"));
      $this->render('article');
    }
    else
    {
      $this->set('articles', $this->Blog->find('all'));
    }
  }
}
?>

以下是我单击其中一个项目将得到的错误：

Notice (8): Undefined index: id = 2 [CORE\Cake\Model\Model.php, line 2666]

你可能想要这个：

    $this->set('article', $this->Blog->find('first', array('conditions' => array('Blog.id' => $view))));

见：

    $this->set('article', $this->Blog->find('first', array('conditions' => array('Blog.id' => $view))));
