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');

如下图所示建立工程：

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; ?>   
 
Id 

company 

price 

change 

last 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']; ?>

Id	company	price	change	last 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']; ?>
