正确的模型关系，对cakephp2主键和外键查询

我有加盟商的租金设备我的客户是租掉加盟两个加盟商和顾客是用户正确的模型关系，对cakephp2主键和外键查询

我有一个用户表，加盟商表，客户表和预订表。

的表是这样的：

CREATE TABLE IF NOT EXISTS `franchisees` (
    `id` int(11) NOT NULL AUTO_INCREMENT, 
    `user_id` int(11) DEFAULT NULL, 
    `group_id` int(11) DEFAULT NULL, 
    `firstname` varchar(20) DEFAULT NULL, 
    `lastname` varchar(20) DEFAULT NULL, 
    `address1` varchar(150) DEFAULT NULL, 
    `address2` varchar(150) DEFAULT NULL, 
    `city` varchar(20) DEFAULT NULL, 
    `postcode` varchar(10) DEFAULT NULL, 
    `phone` varchar(15) DEFAULT NULL, 
    `alt_phone` varchar(15) DEFAULT NULL, 
    `lat` float DEFAULT NULL, 
    `lng` float DEFAULT NULL, 
    `created` timestamp NULL DEFAULT NULL, 
    `modified` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP, 
    PRIMARY KEY (`id`) 
) ENGINE=InnoDB DEFAULT CHARSET=latin1 ; 

CREATE TABLE IF NOT EXISTS `customers` (
    `id` int(11) NOT NULL AUTO_INCREMENT, 
    `user_id` int(11) DEFAULT NULL, 
    `group_id` int(11) DEFAULT NULL, 
    `firstname` varchar(20) DEFAULT NULL, 
    `lastname` varchar(20) DEFAULT NULL, 
    `address1` varchar(150) DEFAULT NULL, 
    `address2` varchar(150) DEFAULT NULL, 
    `city` varchar(20) DEFAULT NULL, 
    `postcode` varchar(10) DEFAULT NULL, 
    `phone` varchar(15) DEFAULT NULL, 
    `alt_phone` varchar(15) DEFAULT NULL, 
    `lat` float DEFAULT NULL, 
    `lng` float DEFAULT NULL, 
    `created` timestamp NULL DEFAULT NULL, 
    `modified` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP, 
    PRIMARY KEY (`id`) 
) ENGINE=InnoDB DEFAULT CHARSET=latin1 ; 

CREATE TABLE IF NOT EXISTS `bookings` (
    `id` int(11) NOT NULL AUTO_INCREMENT, 
    `customer_id` int(11) DEFAULT NULL, 
    `franchisee_id` int(11) DEFAULT NULL, 
    `booking_date` timestamp NULL DEFAULT CURRENT_TIMESTAMP, 
    `start_date` datetime DEFAULT NULL, 
    `end_date` datetime NOT NULL, 
    `event_location` text, 
    `price` float DEFAULT NULL, 
    PRIMARY KEY (`id`) 
) ENGINE=InnoDB DEFAULT CHARSET=latin1 ;

我的模型关系的定义是这样的：

加盟商

public $name = 'Franchisee'; 
public $hasMany = array(
    'FranchiseeBooking' => array(
     'className' => 'Booking', 
     'foreignKey' => 'franchisee_id' 
    ) 
);

客户

public $name = 'Customer'; 
public $hasMany = array(
    'CustomerBooking' => array(
     'className' => 'Booking', 
     'foreignKey' => 'customer_id' 
    ) 
);

预订

public $name = 'Booking'; 
public $belongsTo = array(
    'Customers' => array(
     'className' => 'Customer', 
     'foreignKey' => 'customer_id' 
    ), 
    'Franchisees' => array(
     'className' => 'Franchisee', 
     'foreignKey' => 'franchisee_id' 
    ) 
);

所以，我想查询预订表（其中franchisee_id被登录的用户），并得到了加盟商的预订，酒店以及相关的客户数据。

$options = array('conditions' => array('Booking.franchisee_id' => $this->_authUser)); 
$bookings = $this->Booking->find('all');

结果在下面的查询：

SELECT `Booking`.`id`, `Booking`.`customer_id`, `Booking`.`franchisee_id`, `Booking`.`booking_date`, `Booking`.`start_date`, `Booking`.`end_date`, `Booking`.`event_location`, `Booking`.`price`, `BookingCustomers`.`id`, `BookingCustomers`.`user_id`, `BookingCustomers`.`group_id`, `BookingCustomers`.`firstname`, `BookingCustomers`.`lastname`, `BookingCustomers`.`address1`, `BookingCustomers`.`address2`, `BookingCustomers`.`city`, `BookingCustomers`.`postcode`, `BookingCustomers`.`phone`, `BookingCustomers`.`alt_phone`, `BookingCustomers`.`lat`, `BookingCustomers`.`lng`, `BookingCustomers`.`created`, `BookingCustomers`.`modified`, `BookingFranchisees`.`id`, `BookingFranchisees`.`user_id`, `BookingFranchisees`.`group_id`, `BookingFranchisees`.`firstname`, `BookingFranchisees`.`lastname`, `BookingFranchisees`.`address1`, `BookingFranchisees`.`address2`, `BookingFranchisees`.`city`, `BookingFranchisees`.`postcode`, `BookingFranchisees`.`phone`, `BookingFranchisees`.`alt_phone`, `BookingFranchisees`.`lat`, `BookingFranchisees`.`lng`, `BookingFranchisees`.`created`, `BookingFranchisees`.`modified` FROM `trailblazer`.`bookings` AS `Booking` LEFT JOIN `trailblazer`.`customers` AS `BookingCustomers` ON (`Booking`.`customer_id` = `BookingCustomers`.`id`) LEFT JOIN `trailblazer`.`franchisees` AS `BookingFranchisees` ON (`Booking`.`franchisee_id` = `BookingFranchisees`.`id`) WHERE 1 = 1

看起来像这样当阵列打印出来：

Array 
(
    [0] => Array 
     (
      [Booking] => Array 
       (
        [id] => 1

        [end_date] => 2013-03-08 11:45:00 
        [event_location] => Belfast 
        [price] => 900 
       ) 

      [BookingCustomers] => Array 
       (
        [id] => 
        [user_id] =>

      [BookingFranchisees] => Array 
       (
        [id] =>

     )

        [event_location] => 
        [price] => 6750 
       ) 

      [BookingCustomers] => Array 
       (
        [id] => 
        [user_id] =>

        [firstname] => 
        [lastname] =>

        [address2] => 
        [city] => 
        [postcode] => 
        [phone] => 
        [alt_phone] => 
        [lat] => 
        [lng] => 
        [created] => 
        [modified] => 
       ) 

      [BookingFranchisees] => Array 
       (
        [id] => 
        [user_id] => 
        [group_id] => 
        [firstname] => 
        [lastname] => 
        [address1] => 
        [address2] => 
        [city] =>

        [lng] => 
        [created] => 
        [modified] => 
       ) 

     ) 

)

正如你所看到的，我没有得到相关数据。我有一种感觉，这个问题与主键和外键有关，但我不知道我错在哪里。任何人都可以解释这一点？（我使用cakephp 2.3）

确保设置了'$ recursive = -1;'，然后发布它生成的新查询。此外，为什么你使用别名而不是“预订”你的hasMany关联？ – Dave 2013-02-26 16:01:44

是否有任何数据插入到相应的表中？在我看来，你的关系是好的，因为你的find（）方法获取所需的所有数据。问题是你的表可能没有任何数据。 – 2013-02-26 17:15:14

我相信你的用户ID没有被正确调用。尝试：

$options = array('conditions' => array('Booking.franchisee_id' => $this->Auth->user('id')));
