I use select_tag to create a selection box in a view and how can I get
the current selection value in its controller? For example:
select_tag:project_selection,options_for_select(@project_names),
:onchange
=>remote_function(:update=>'posts',:loading=>'false',
:url => { :action => :update_project_selection })
in the action "update_project_selection", how can I get the current
selection?
thanks,
