Rails - Jul 2010 - Search...

Hi,

I''ve implemented two boxes of research which correspond to two columns
of my table. This solution works well:

In my index.html.erb:
       <% form_tag search_intervenants_path, :method => :get do %>
               <%= label_tag "code" %>
               <%= text_field_tag "search[by_code]",
params[:search].try(:
[], :code) %>
               <%= label_tag "id" %>
               <%= text_field_tag "search[by_id]",
params[:search].try(:[], :id) %>
           <%= submit_tag "Search" %>
         <% end %>

In my controller:
def search
       @intervenants = Intervenant.search(params[:search])
   render :index
 end

In my model:
 def self.search(params)
     params.keys.inject(scoped({})) do |found, k|
     params[k].blank?  ? found : found.send(:"#{k}", params[k])
       end
 end
  scope :by_code, lambda {|name| where("intervenants.code LIKE ?",
"%#{name}%")}
  scope :by_id, lambda {|name| where("intervenants.id LIKE ?",
"%#{name}%")}

I would like to have an only search area, I tried but I didn''t suceed
in it... Who can help me? Thanks a lot !
