如何使用ThinkingSphinx对多个模型进行地理搜索？

Question

我有两个模型索引搜索（用户和项目）。我试图做模型之间的地理搜索：

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

但我只得到一个错误：

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

搜索每个模型单独正常工作......但我我不知道这里的问题是什么。这里有指标：

用户索引：

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  

项目指标：

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 

Answer 1

这是一个迟到的反应，但有总比没有好，希望：

当你不在特定模型上搜索，思维狮身人面像没有参考点来知道什么属性可用，所以你需要明确告诉它使用的经纬度和长度属性：

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" 
)
