link_to to pass an entire row of a table

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
