当我在模型中加载数据库时，如何在Codeigniter Profiler中显示我的数据库查询？ [英] How can I display my database queries in the Codeigniter Profiler when I load my databases in my models?

问题描述

我的Codeigniter系统使用多个数据库。我不需要每个页面上的每个数据库，所以我加载每个连接在模型中需要它，然后在每个控制器中加载所需的模型。

My Codeigniter system uses multiple databases. I don't need every database on every page, so I load each connection in the model where it's needed, then load the required models within each controller. The profiler does not display any of the queries from these databases when I load things this way.

这是我在我的模型中加载数据库的方法：

This is how I load the databases in my models:

$this->Companies_db = $this->load->database( 'companies', TRUE, TRUE );

我用来加载MY_Controller（）（核心控制器的扩展）中的所有数据库。当我加载它们，分析器工作正常。当我在我的模型中加载它们时，它不显示数据库查询。

I used to load all my databases in MY_Controller() ( an extension of the core controller ). When I load them there, the profiler works fine. When I load them in my models, it displays no database queries.

数据库查询正在 _compile_queries c $ c>在 system / libraries / Profiler.php 中。当我的数据库在模型中加载时，它们的对象不会加载到CI对象中。下面的代码是 _compile_queries（）方法的前几行，是发生这种情况的地方。

The database queries are being compiled in the method _compile_queries() within system/libraries/Profiler.php. When my databases are loaded in the model, their objects are not loading into the CI object. The code below is the first few lines from the _compile_queries() method and is where this is happening.

foreach (get_object_vars($this->CI) as $CI_object)
    {
        if (is_object($CI_object) && is_subclass_of(get_class($CI_object), 'CI_DB') )
        {
            $dbs[] = $CI_object;
        }
    }

如何获取CI分析器在我的模型中加载数据库时显示我的查询或者，更具体地说，当数据库加载到模型中时，如何将我的数据库对象加载到主CI对象中。

How do I get the CI profiler to display my queries when I load my databases in my models? Or, more specifically, how do I get my database objects to load into the main CI object when the databases are loaded in the models.

推荐答案

我会得到一个CI对象的实例，并将您的数据库存储在那里，这样也可以用于分析器。

I would get an instance of the CI-object and store your database there, so that is also available to the profiler.

class My_Model {
     private $Companies_db;

     public function __construct(){
           $this->Companies_db = $this->load->database( 'companies', TRUE, TRUE );

           // Pass reference of database to the CI-instance
           $CI =& get_instance();
           $CI->Companies_db =& $this->Companies_db;  
     }
}
