Question

我有两张这样的表：

CREATE TABLE IF NOT EXISTS `publications` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `numerated` tinyint(1) NOT NULL DEFAULT '0',
  `title` text COLLATE utf8_unicode_ci,
  `collection_id` int(11) NOT NULL,
  `note` text CHARACTER SET utf8,
  `adminNote` text CHARACTER SET utf8,
  PRIMARY KEY (`id`),
  KEY `collectionId` (`collection_id`)
  KEY `numerated` (`numerated`),
) ;



CREATE TABLE IF NOT EXISTS `publication_numerations` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `publication_id` int(11) NOT NULL,
  `published` tinyint(1) NOT NULL DEFAULT '0',
  `book` int(11) DEFAULT NULL,
  `number` int(11) DEFAULT NULL,
  PRIMARY KEY (`id`),
  KEY `publication_id` (`publication_id`)
) ;



CREATE TABLE IF NOT EXISTS `properties` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `publication_id` int(11) NOT NULL,
  `value` varchar(255) CHARACTER SET utf8 DEFAULT NULL,
  PRIMARY KEY (`id`),
  KEY `publication_id` (`publication_id`)
)

我需要的是从表发布和publication_numerations中获取所有记录的列表。尝试蛋糕烘烤模型/控制器/视图，但它一直加入出版物和属性，没有publication_numerations。

你能帮我解决一下吗？

非常感谢你！

更新：所以，我需要的是创建并使用它作为默认查询：

SELECT * FROM `publications` 
LEFT JOIN `publication_numerations` ON (`publications`.`id` = publication_numerations.`publication_id`)

出版物模型

    var $hasOne = array(
        'Publisher' => array(
            'className' => 'Publisher',
            'foreignKey' => 'publication_id',
            'conditions' => '',
            'fields' => '',
            'order' => ''
        ), 
    );

    var $belongsTo = array(
        'Collection' => array(
            'className' => 'Collection',
            'foreignKey' => 'collection_id',
            'conditions' => '',
            'fields' => '',
            'order' => ''
        )
    );

    var $hasMany = array(
        'PublicationProperty' => array(
            'className' => 'PublicationProperty',
            'foreignKey' => 'publication_id',
            'dependent' => false,
            'conditions' => '',
            'fields' => '',
            'order' => '',
            'limit' => '',
            'offset' => '',
            'exclusive' => '',
            'finderQuery' => '',
            'counterQuery' => ''
        ),
        'PublicationNumeration' => array(
            'className' => 'PublicationNumeration',
            'foreignKey' => 'publication_id',
            'conditions' => '',
            'fields' => '',
            'order' => ''
        )
    );

PublicationNumeration模型
var $belongsTo = array( 'Publication' => array( 'className' => 'Publication', 'foreignKey' => 'publication_id', 'conditions' => '', 'fields' => '', 'order' => '' ) ); var $hasMany = array( 'Publication' => array( 'className' => 'Publication', 'foreignKey' => 'publication_id', 'conditions' => '', 'fields' => '', 'order' => '' ) ); } ？＆GT;
收集模式
var $hasMany = array( 'Property' => array( 'className' => 'Property', 'foreignKey' => 'collection_id', 'dependent' => false, 'conditions' => '', 'fields' => '', 'order' => '', 'limit' => '', 'offset' => '', 'exclusive' => '', 'finderQuery' => '', 'counterQuery' => '' ), 'Publication' => array( 'className' => 'Publication', 'foreignKey' => 'collection_id', 'dependent' => false, 'conditions' => '', 'fields' => '', 'order' => '', 'limit' => '', 'offset' => '', 'exclusive' => '', 'finderQuery' => '', 'counterQuery' => '' ) ); } ？＆GT;

Answer 1

你可以像这样加入蛋糕：

$joins = array(
     array('table' => 'publication_numerations',
       'alias' => 'PublicationNumeration',
       'type' => 'LEFT',
       'conditions' => array(
          'Publication.id = PublicationNumeration.publication_id',
       )
     )
);

$this->Publication->find('all', array('joins' => $joins));

Answer 2

尝试用蛋糕烘烤模型/控制器/视图，但所有它加入出版物的时间和属性，没有 publication_numerations。

因此，手动创建关联 - Associations: Linking Models Together。你似乎不需要'加入'。通过正确设置关联，您可以使用控制器中的find('list')获取所需的列表 - http://book.cakephp.org/view/1017/Retrieving-Your-Data#find-list-1022。

Answer 3

尝试将 $ join 数组的类型属性设置为'LEFT OUTER'，而不是'LEFT'。

如何离开外连接下表？
