Hi all,

I have used url aliasing on my site. say suppose my url is

domain/blog/1 to domain/blog/1/title in this i have succeded to redirect  
the url to a particular blog on its id with blog title, by defining the  
routes

map.blog ‘blog/edit/:id/:title’, :id=\> ‘id’, :controller =\> ‘blog’,  
:action =\> ‘show’

when i edit a particular blog it is giving me this error like

Couldn’t find Service with ID=update

means it is not getting the id for tht blog, so wht should i define in  
controller or in routes so tht i can take id of tht blog with title,  
???//\>???

any help would be appreciated,

Thanks a lot
