如何使用ThinkingSphinx對多個模型進行地理搜索？

Question

我有兩個模型索引搜索（用戶和項目）。我試圖做模型之間的地理搜索：

ThinkingSphinx::Search.search('keywords', :geo => [ degrees_to_radians(params[:lat].to_f), degrees_to_radians(params[:lon].to_f) ], )

但我只得到一個錯誤：

Sphinx Error: index item_core,item_delta,user_core,user_delta: unknown latitude attribute ''

搜索每個模型單獨正常工作......但我我不知道這裏的問題是什麼。這裏有指標：

用戶索引：

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  

項目指標：

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

這是一個遲到的反應，但有總比沒有好，希望：

當你不在特定模型上搜索，思維獅身人面像沒有參考點來知道什麼屬性可用，所以你需要明確告訴它使用的經緯度和長度屬性：

ThinkingSphinx::Search.search('keywords', 
    :geo => [ 
    degrees_to_radians(params[:lat].to_f), 
    degrees_to_radians(params[:lon].to_f) 
    ], 
    :latitude_attr => "latitude", 
    :longitude_attr => "longitude" 
)
