php - CakePHP:保存从 MySQL View 加载的模型

Question

我有一个 CakePHP 模型“Person”，它从 mysql View 加载其数据(public $useTable = 'people_rel';，people_rel 是 View )。
该 View 将一些数据连接到表“people”。

View prefix_people_rel:

CREATE 
    ALGORITHM = UNDEFINED 
    DEFINER = `xxxxxxx`@`%` 
    SQL SECURITY DEFINER
VIEW `prefix_people_rel` AS
    select 
        `prefix_people`.`id` AS `id`,
        `prefix_people`.`username` AS `username`,
        `prefix_people`.`first_name` AS `first_name`,
        `prefix_people`.`last_name` AS `last_name`,
        `prefix_people`.`email` AS `email`,
        `prefix_people`.`password` AS `password`,
        `prefix_people`.`status` AS `status`,
        `prefix_people`.`outpost_id` AS `outpost_id`,
        `prefix_outposts`.`region_id` AS `region_id`,
        `prefix_regions`.`district_id` AS `district_id`,
        `prefix_districts`.`country_id` AS `country_id`
    from
        (((`prefix_people`
        left join `prefix_outposts` ON ((`prefix_people`.`outpost_id` = `prefix_outposts`.`id`)))
        left join `prefix_regions` ON ((`prefix_outposts`.`region_id` = `prefix_regions`.`id`)))
        left join `prefix_districts` ON ((`prefix_regions`.`district_id` = `prefix_districts`.`id`)))

表 prefix_people:

列region_id、district_id和country_id在此模型中是只读的，它们可以在模型Outpost、Region和District中进行编辑。
问题是我无法保存模型，因为它是从 View 加载的。
我想从 View people_rel 加载数据并将它们保存到表 people 中。我怎样才能做到这一点？ (我使用 CakePHP 2.5.3，并希望在稳定版本可用后升级到 3)

非常感谢!

这没有帮助:
模特:

public function beforeSave($options = array())
{
    // ... Password hashing ...
    $this->useTable = 'people';
    return true;
}

public function afterSave($created, $options = array()) {
    $this->useTable = 'people_rel';
}

一个非常相似的解决方案是有效的。请参阅下面的答案。

Answer 1

根据 Nunser 的想法，我找到了解决方案。
在模型中，我添加了beforeSave()和afterSave():

public function beforeSave($options = array())
{
    //$this->useTable = 'people'; <= Does not work
    $this->setSource('people'); // Works
    return true;
}

public function afterSave($created, $options = array()) {
    //$this->useTable = 'people_rel'; <= Does not work
    $this->setSource('people_rel'); // Works
}

删除对象所必需的:

public function beforeDelete($cascade = true) {
    $this->setSource('people');
    return true;
}

public function afterDelete() {
    $this->setSource('people_rel');
}
