Dear Guys,
I have created the drop down list for state and city. Now when the user 
selects the state say florida and city say miami, I want to display these 
names on the new page when the user clicks the search link. Using link_to,  
I am not able to pass these names to the new page. Ideally these selected 
names should go as :paramsbut they arent going through the url .Please me 
know if its still not clear. Thanks a lot!! Heres the code:

<%= form_for Investopp.new do |f| %><div class="field"><%= f.label :state_id 
%><br/><%= f.collection_select  :state_id, Investopp.year_lookup(@state_ids), 
:label, :value, include_blank: true %></div>
<div class="field"><%= f.label :city_id, "city" %><br /><%= 
f.grouped_collection_select :city_id, Investopp.year_lookup(@state_ids), 
:cities, :value, :id,:name, include_blank: true %></div><% end %><%= link_to 
'Back', investopps_path %><%= link_to 'Search', investopps_browsedisplay_path %>
