好吧，在我的 cakephp 项目中，我有 6 个模型，它们是 {User,Property,Category,Status,Comments,Attachable}
属性模型： $belongsTo = {User,Category,Status} 。和 $hasMany = {评论，可附加} ..
属性控制器索引方法..
public function index() {
$this->Property->recursive = 0;
$this->set('properties', $this->paginate());
$properties= $this->paginate();
//pr($properties);
//exit;
}
输出：
Array
(
[0] => Array
(
[Property] => Array
(
[id] => 1
[user_id] => 1
[category_id] => 1
)
[User] => Array
(
[id] => 1
[name] => zals
[username] => admin
[userLevel] => 1
)
[Category] => Array
(
[id] => 1
[name] => villa
[property_count] => 0
)
[Status] => Array
(
[id] => 1
[name] => New
[property_count] => 0
)
)
[1] => Array
(
[Property] => Array
(
[id] => 2
[user_id] => 1
[phone] => 78666
)
[User] => Array
(
[id] => 1
[name] => zals
[username] => admin
)
[Category] => Array
(
[id] => 1
[name] => villa
[description] => villas are iby a wealthy person.
[property_count] => 0
)
[Status] => Array
(
[id] => 1
[name] => New
[description] => New Property
[property_count] => 0
)
)
[2] => Array
(
[Property] => Array
(
[id] => 3
[user_id] => 1
[category_id] => 1
)
[User] => Array
(
[id] => 1
[name] => zals
[username] => admin
[email] => admin@realty.com
[userLevel] => 1
)
[Category] => Array
(
[id] => 1
[name] => villa
[property_count] => 0
)
[Status] => Array
(
[id] => 1
[name] => New
[property_count] => 0
)
)
)
那么上面的方法只从 $belongsTo 变量中的模型中检索数据。我想要的是将相关的评论和可附加模型与相同的查询结合起来。这可以通过 LEFT JOIN 手动查询评论和附加模型。
这就是查询的样子
function index() {
$properties = $this->Property->query("SELECT `Property`.`id`, `Property`.`user_id`, `Property`.`category_id`, `Property`.`status_id`, `Property`.`state_id`, `User`.`id`, `User`.`name`, `User`.`username`,`Category`.`id`, `Category`.`name`, `Category`.`description`, `Status`.`name`, `Status`.`description``Comment`.`id`,`Comment`.`name`,`Comment`.`comment`,`Attachment`.`id`,`Attachment`.`AttachmentName` FROM `properties` AS `Property`
LEFT JOIN `users` AS `User` ON (`Property`.`user_id` = `User`.`id`)
LEFT JOIN `categories` AS `Category` ON (`Property`.`category_id` = `Category`.`id`)
LEFT JOIN `statuses` AS `Status` ON (`Property`.`status_id` = `Status`.`id`)
LEFT JOIN `cities` AS `City` ON (`Property`.`city_id` = `City`.`id`)
LEFT JOIN `comments` AS `Comment` ON (`Property`.`id` = `Comment`.`id`)
LEFT JOIN `attachments` AS `Attachment` ON (`Property`.`id` = `Attachment`.`id`) WHERE 1 = 1 LIMIT 20");
//pr($properties);
//exit;
$this->set('properties',$properties);
}
输出：
Array
(
[0] => Array
(
[Property] => Array
(
[id] => 1
[user_id] => 1
[category_id] => 1
[status_id] => 1
)
[User] => Array
(
[id] => 1
[name] => za
[username] => admin
)
[Category] => Array
(
[id] => 1
[name] => villa
[description] => villa by a wealthy person.
)
[Status] => Array
(
[name] => New
)
[Comment] => Array
(
[id] => 1
[name] => A
[comment] => hello
)
[Attachment] => Array
(
[id] => 1
[AttachmentName] => 1342009083_4c2380.jpg
)
)
[1] => Array
(
[Property] => Array
(
[id] => 2
[user_id] => 1
[category_id] => 1
[status_id] => 1
)
[User] => Array
(
[id] => 1
[name] => zals
[username] => admin
)
[Category] => Array
(
[id] => 1
[name] => villa
[description] => villas a
)
[Status] => Array

[Comment] => Array

)
[Attachment] => Array
(
[id] => 2
[AttachmentName] => 92f2e3c067d731a3823762.jpg
)
)
)
我确信后一种方法不是正确的方法。或者
假设我在控制器中使用了 cakephp 的默认索引方法，并且在 VIEW 中我可以在主 foreach 循环内执行嵌套的 foreach 循环..即
<?php foreach ($properties as $property) { ?>
$id = $property['Property']['id'];
$comments = ..... //here to query for the associated comments passing the id value ..
?>
可以这样解决吗？或如何？请指导..谢谢..
