Dropdown menu for product search

I have many products with many categories that are related to has_many using membership.

I am trying to create a search box in which anyone can search for products and also filter their search with a dropdown of categories (so that only products with matching categories can be retrieved).

Think_sphinx index is in the product model I am not getting any errors but the dropdown does not affect the search.



MODEL: 
    has_many :memberships,:dependent=> :destroy
    has_many :categories, :through => :memberships
    named_scope :published, :conditions => {:publish => 1}
    define_index do
        indexes product_name
        indexes product_description
        indexes publish
        indexes memberships.product_id
        indexes memberships.category_id
        indexes categories.category_name
      end
    end

CONTROLLER: 
     @products = Product.search params[:search],:conditions=>{@product.memberships.category_id =>params[:category_product] },:page=> params[:page] || 1,:per_page =>4


VIEW:
           form_tag search_path, :method =>:get do 
           text_field_tag :search, params[:search]
           form_tag categories_path, :method => :get do 
           select_tag"category", options_from_collection_for_select (Category.find (:all,   :group=>:id), :id, :category_name,params[:category_product]) 
           end 
           submit_tag "search", :name => nil 
           end

You need to use the attribute for filtering. In your define_index use the "has" method, and in your search use: with parameters. Something like:

define_index do
  …
  has categories(:id), :as => categories_id
  …
end


and the search will look like this:

Product.search params[:search], :with => { :categories_id => params[:category] }
+1
