route parameters with "/"

Hello everyone,

I have a problem about routing

First of all, routes.php

Route::resource('user,'UserController');

url
user/{slug}/edit/

normally it works fine but if slug contains "/" (e.g. abc/123) it will breaks the routing and causes page not found.

I did some search about this issue and I found one in StackOverFlow
http://stackoverflow.com/questions/21552604/how-to-define-a-laravel-route-with-a-parameter-that-contains-a-slash-character

What if i need to do if I define routes using "resource" to handle this problem and is it good to allow route parameters contains "/" ?
Thanks a lot
