Link_to to pass an entire row of a table rather than by id

Hi

How can i use link_to in form to pass an already fetched row of a
table to an action.I can pass it by :id...But in action i have to again
use the find method to get the rows again

in show.rhtml I have

<%= link_to 'Edit Resolution', :controller => 'service_desk',:action =>
'define_sd_resolution_ui', :id => @sd_ticket %>

Here @sd_ticket contains title ,owner etc..Which i can print in the
show.rhtml like

@sd_ticket.title
@sd_ticket.owner

How can I pass the entire @sd_ticket to action define_sd_resolution_ui
?(rather by using :id)..If I use the above link to then again i have to
get data using find
again
Pls help
Sijo
