首先建立数据库cake_ext，并执行如下sql文：

CREATE TABLE `companies` (
  `id` int(11) NOT NULL auto_increment,
  `company` varchar(50) NOT NULL,
  `price` decimal(8,2) NOT NULL,
  `change` decimal(8,2) NOT NULL,
  `lastudp` date NOT NULL,
  PRIMARY KEY  (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=8 DEFAULT CHARSET=utf8;

-- Records 

INSERT INTO `companies` VALUES ('1', '3m Co', '71.72', '0.02', '2008-10-21');
INSERT INTO `companies` VALUES ('2', 'Alcoa Inc', '29.01', '0.42', '2008-10-20');
INSERT INTO `companies` VALUES ('3', 'AT&T Inc.', '31.61', '-0.48', '2008-10-21');
INSERT INTO `companies` VALUES ('4', 'Boeing Co.', '75.43', '0.53', '2008-10-13');
INSERT INTO `companies` VALUES ('5', 'United Technologies Corporation', '63.26', '0.55', '2008-10-09');
INSERT INTO `companies` VALUES ('6', 'Intel Corporation', '19.88', '0.31', '2008-10-15');
INSERT INTO `companies` VALUES ('7', 'Exxon Mobil Corp', '68.10', '-0.43', '2008-10-17');

数据库配置文件如下：

class DATABASE_CONFIG
{
    var $default = array('driver' => 'mysql',
                                'connect' => 'mysql_connect',
                                'host' => 'localhost',
                                'login' => 'root',
                                'password' => 'root',
                                'database' => 'cake_ext',
                                'prefix' => '');
    var $test = array('driver' => 'mysql',
                            'connect' => 'mysql_connect',
                            'host' => 'localhost',
                            'login' => 'root',
                            'password' => 'root',
                            'database' => 'cake_ext',
                            'prefix' => '');
}
companies_controller.php：
class CompaniesController extends AppController
{
    var $name = 'Companies';
    
    function index()
    {
        $this->set('companies', $this->Company->findAll());
    }
    
    function view($id = null)
    {
        $this->Company->id = $id;
        $this->set('company', $this->Company->read());
    }
}
?>

company.php：

class Company extends AppModel
{
    var $name = 'Company';
}
?>

index.thtml：

Test companies

foreach ($companies as $company): ?>
endforeach; ?>  
Idcompanypricechangelast update
echo $company['Company']['id']; ?>
echo $html->link($company['Company']['company'], "/companies/view/".$company['Company']['id']); ?>
echo $company['Company']['price']; ?>echo $company['Company']['change']; ?>echo $company['Company']['lastudp']; ?>
view.tthtml：
Company: echo $company['Company']['company']?>
Id: echo $company['Company']['id']?>

Price: echo $company['Company']['price']?>

Change: echo $company['Company']['change']?>

LastUpdate: echo $company['Company']['lastudp']?>

访问

http://localhost/cakephp/companies

即可运行测试程序。
