using routing on codeigniter

[eluser]gordon Stewart[/eluser]
hello, I am trying to adjust

/application/config/routes.php so I can have flexible URL's

what I'm after, is to have a URL of

http://domain.com/maps/
http://domain.com/maps/region_name_1
http://domain.com/maps/region_name_2 etc...


I have

application/controllers/maps.php

and

application/models/maps_model.php


routes.php >> i have this line :-


$route['maps/(:any)'] = "maps/maps_model/$1";



is that above correct ?


when I put in my url maps/region_name or maps/region I get a 404 error

EDIT:-

from my logs, I see :-

ERROR - 2010-05-15 03:41:40 --> 404 Page Not Found --> maps/maps_model

is maps_model in a subdirectory of my controllers directory ????

or should it be in my 'models' directory ?
