CakePHP：从MySQL View加载的Save Model

Question

我有一个CakePHP模型“Person”，它从mysql视图加载数据（public $useTable = 'people_rel';，people_rel是视图）。
视图将一些数据连接到表'people'。

视图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：

在此模型中，region_id，district_id和country_id列是只读的，它们在模型Outpost，Region和District中进行编辑。
问题是我无法保存模型，因为它是从视图加载的 我想从视图people_rel加载数据并将它们保存到表人员中。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时升级到3）

非常感谢提前！

修改
这没有帮助：
模范人物：

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

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

一个非常类似的解决方案。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');
}
