rails 2.3.x link_to tag

I have this in the view

<%= link_to 'Rename', :controller => 'ocrs', :action => 'rename_file', :query => file_name %>

when i click on the link, i want it to show a prompt box ( just like :confirm =>'Are you sure', :method =>delete) but instead of yes/no , i want the user to input something in that box. ( the name the file is going to be renamed to), and that entry to be available in the controller/action (ocrs / rename_file) .

You can prompt to link button as follows

<%= link_to 'Rename', 'javascript:prompt("Your file name? : ")' %>
