Yii Extendedactiverecord Enhanced ActiveRecord adds multi-database connection binding capabilities

Extendedactiverecord inherit from Cactiverecord, so the basic function is no different from Cactiverecord

To add support for multiple database connections, a callback to the ConnectionName () method is added, and the usage is consistent with the existing TableName () method, which returns a string of database connection component names.

If the method is not defined, the default database connection (db) is used

The source code is as follows:

Class Extendedactiverecord extends cactiverecord{public    static $db = Array ();    /**     * @return cdbconnection     * @throws cdbexception * * Public    function getdbconnection ()    {        $ ComponentName = $this->connectionname ();        if (Isset (self:: $db [$componentName])) {            return self:: $db [$componentName];        } else {self            :: $db [$ ComponentName] = Yii::app ()->getcomponent ($componentName);            if (self:: $db [$componentName] instanceof Cdbconnection)                return to self:: $db [$componentName];            else {                $message = ' Active Record keyword requires a '. $componentName. ' cdbconnection application component. ';                Yii::log ($message, Clogger::level_error, ' extended ');                throw new CDBException (Yii::t (' Yii ', $message));    }}} Public Function ConnectionName ()    {        return ' db ';    }}

Instance:

Class Somemodelclass extends extendedactiverecord{...    Public Function ConnectionName () {        return ' some-db-connection ';    }    ......}
