正確的模型關係，對cakephp2主鍵和外鍵查詢

我有加盟商的租金設備我的客戶是租掉加盟兩個加盟商和顧客是用戶正確的模型關係，對cakephp2主鍵和外鍵查詢

我有一個用戶表，加盟商表，客戶表和預訂表。

的表是這樣的：

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 ;

我的模型關係的定義是這樣的：

加盟商

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

客戶

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

預訂

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

所以，我想查詢預訂表（其中franchisee_id被登錄的用戶），並得到了加盟商的預訂，酒店以及相關的客戶數據。

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

結果在下面的查詢：

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

看起來像這樣當陣列打印出來：

Array 
(
    [0] => Array 
     (
      [Booking] => Array 
       (
        [id] => 1 
        [customer_id] => 8 
        [franchisee_id] => 7 
        [booking_date] => 2013-02-25 11:44:29

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

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

      [BookingFranchisees] => Array 
       (

     )

        [end_date] => 2013-02-23 16:15:00 
        [event_location] => 
        [price] => 6750 
       ) 

      [BookingCustomers] => Array 
       (
        [id] => 
        [user_id] => 
        [group_id] => 
        [firstname] => 
        [lastname] => 
        [address1] => 
        [address2] => 
        [city] => 
        [postcode] => 
        [phone] => 
        [alt_phone] => 
        [lat] => 
        [lng] => 
        [created] => 
        [modified] => 
       ) 

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

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

     ) 

)

正如你所看到的，我沒有得到相關數據。我有一種感覺，這個問題與主鍵和外鍵有關，但我不知道我錯在哪裏。任何人都可以解釋這一點？（我使用cakephp 2.3）

確保設置了'$ recursive = -1;'，然後發佈它生成的新查詢。此外，爲什麼你使用別名而不是「預訂」你的hasMany關聯？ – Dave 2013-02-26 16:01:44

是否有任何數據插入到相應的表中？在我看來，你的關係是好的，因爲你的find（）方法獲取所需的所有數據。問題是你的表可能沒有任何數據。 – 2013-02-26 17:15:14

我相信你的用戶ID沒有被正確調用。嘗試：

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