how can I put a simple search form into the application layout in rails 2.3.x?

I want to create a search form that appears in the header of my application (like the search in Stackoverflow).

T do this, I thought that I would put it into the layout for application.html.erb

But then what do I use as a route and action in the controller?

I want to pass the parameter to search through several ActiveRecords, probably using searchlogic.

Thanks.

This is very simple, may index with texticle later:

Here is my searches_controller.rb

  1 class SearchesController < App开发者_开发问答licationController
  2 
  3   def search
  4 
  5     @contacts_search = Contact.search(:first_name_like => params[:search])
  6 
  7 
  8 
  9   end
 10 end

You should use a SearchController. I use ThinkingSphinx and it works fine, so no code to help there, but using a SearchController will allow you to route that way quite easily.

    <% form_tag search_search_path, :method => :get do %>
    <p id="search_header">
        <%= text_field_tag 'q', params[:q], {:size => 40} %>
        <%= submit_tag 'Search for Shops', :name => nil %>
        </p>
    <% end %>

Something like this. I called my search method search in the Search controller... that's why the double search in the route.
