I have two models indexed for searching (User and Item). I’m trying to do a geo-search across models:
ThinkingSphinx::Search.search('keywords', :geo => [ degrees_to_radians(params[:lat].to_f), degrees_to_radians(params[:lon].to_f) ], )
But I only get an error:
Sphinx Error: index item_core,item_delta,user_core,user_delta: unknown latitude attribute ''
Searching each model individually works fine… but I’ve no idea what the problem here is. Here are the indexes:
User Index:
define_index do indexes [:first_name, :last_name], :as => :name indexes login indexes email indexes headline indexes description indexes business.name, :as => :business_name indexes [addresses.street_1, addresses.street_2, addresses.city, addresses.postal_code], :as => :address has created_at, :sortable => true has addresses.latitude, :as => :latitude, :type => :float has addresses.longitude, :as => :longitude, :type => :float set_property :delta => true end Item index:
define_index do indexes title, :sortable => true indexes description indexes [address.street_1, address.street_2, address.city, address.postal_code], :as => :address indexes images.title, :as => :image_titles indexes images.description, :as => :image_descriptions indexes categories(:name), :as => :category_names has price, :sortable => true has created_at, :sortable => true has address.latitude, :as => :latitude, :type => :float has address.longitude, :as => :longitude, :type => :float has categories(:id), :as => :category_ids where '`items`.`state` = 'for_sale'' set_property :delta => true end
This is a late response, but better than nothing, hopefully:
When you’re not searching on a specific model, Thinking Sphinx has no reference point for knowing what attributes are available, so you need to explicitly tell it the lat and long attributes to use:
