Yii - Eliminate default controller ID for a module from URL - php

Question

I created a module and there exists a default controller inside that. Now I can access the index action (default action) in the default controller like /mymodule/. For all other action i need to specify the controller id in the url like /mymodule/default/register/ . I would like to know is it possible to eliminate the controller id from url for the default controller in a module.
I need to set url rule like this:
before beautify : www.example.com/index.php?r=mymodule/default/action/
after beautify : www.example.com/mymodule/action/
Note: I want this to happen only for the default controller.
Thanks

This is a little tricky because the action part might be considered as a controller or you might be pointing to an existing controller. But you can get away with this by using a Custom URL Rule Class. Here's an example (I tested it and it seems to work well):
class CustomURLRule extends CBaseUrlRule
{
const MODULE = 'mymodule';
const DEFAULT_CONTROLLER = 'default';
public function parseUrl($manager, $request, $pathInfo, $rawPathInfo)
{
if (preg_match('%^(\w+)(/(\w+))?$%', $pathInfo, $matches)) {
// Make sure the url has 2 or more segments (e.g. mymodule/action)
// and the path is under our target module.
if (count($matches) != 4 || !isset($matches[1]) || !isset($matches[3]) || $matches[1] != self::MODULE)
return false;
// check first if the route already exists
if (($controller = Yii::app()->createController($pathInfo))) {
// Route exists, don't handle it since it is probably pointing to another controller
// besides the default.
return false;
} else {
// Route does not exist, return our new path using the default controller.
$path = $matches[1] . '/' . self::DEFAULT_CONTROLLER . '/' . $matches[3];
return $path;
}
}
return false;
}
public function createUrl($manager, $route, $params, $ampersand)
{
// #todo: implement
return false;
}
}
