在关联模型上思考 Sphinx Facets答案

【问题描述】：

是否在关联模型的 int 类型列上定义 facet？如果定义为 facets 的所有字段属于关联模型列，sphinx 是否会将它们转换为字符串？

我正在尝试将我的子表的一列定义为一个方面。之后当我做 Model1.facets 时重建我得到这个错误。

class Model1 < ActiveRecord::Base
  ....

  has_many :communities, :through => :model2

  ...

  define indexes

     ...

     indexes model2.community_id, :as => :community_id, :facet => :true

     ...

  end

end

模型 1 - 当前模型模型 2 - 使用 :through 加入模型

Model1.facets

【解决方案1】：

如果你使用整数作为构面，那么它们应该被定义为属性：

has model2.community_id, :as => :community_id, :facet => :true

indexes 方法适用于字段 - 您希望人们能够搜索的文本数据。我猜使用您网站的人不会在搜索字段中输入社区 ID。如果不是这样，请发表评论，我将详细说明如何将 community_id 既作为字段又作为属性。
