本文介绍了在CakePHP 2.2中为模型和控制器定义全局变量的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

目前我使用的是这样:

  //在bootstrap.php文件
配置:: write ('from','mymail@mydomain.com')

//在控制器或模型文件
$ var = Configure :: read('from')

事情是,我想通过数据库管理这个变量,以便能够以更简单的方式修改它。 p>

我正在考虑用 AppModel 这样做,但是它只能被模型和控制器访问。



在这种情况下该怎么办?



谢谢。

解决方案

您可以创建一个单独的模型/插件,它将映射到数据库中的配置表。然后通过控制器的 $ uses 语句和模型的 App :: import()加载它。

  class SystemSetting extends AppModel {

/ **
*返回所有设置的列表
*
* @access public
* @return array
* /
public function getSettings(){
return $ this-> find('all');
}
}

然后,在您的控制器中:

 类SomeController扩展AppController {

var $ uses = array('SystemSetting');

public function displaySettings(){
$ settings = $ this-> SystemSetting-> getSettings();
// ..您的代码
}
}

模型:

  App :: import('Model','SystemSettings.SystemSetting'); 
$ settings = new SystemSetting();
$ mySettings = $ settings-> getSettings();

这个很好。当然,您还可以在 AppController AppModel 中加载设置,以遵循 DRY 规则。


Currently i am using something like this:

//at bootstrap.php file
Configure::write('from', 'mymail@mydomain.com')

//at controllers or models files
$var = Configure::read('from')

The thing is, i would like to manage that variable through the database to be able to modify it in a simpler way.

I was thinking about doing it with AppModel but then it would only be accessible for Models and not controllers.

What should I do in this case?

Thanks.

解决方案

You can create a separate model / plugin which will be mapped to a configuration table in your database. Then load it through $uses statement for controllers and App::import() for models.

class SystemSetting extends AppModel {

/**
 * Return a list of all settings
 *
 * @access public
 * @return array
 */
    public function getSettings() {        
        return $this->find('all');
    }
}

Then, in your controller:

class SomeController extends AppController {

    var $uses = array('SystemSetting');

    public function displaySettings() {
        $settings = $this->SystemSetting->getSettings();
        // .. your code
    }
}

In model:

App::import('Model', 'SystemSettings.SystemSetting');
$settings = new SystemSetting();
$mySettings = $settings->getSettings();

This works just fine. Of course, you might also load settings in both AppController and AppModel to follow the DRY rule.
