未定義的方法`define_index'與思維 - 斯芬克斯

Question

當我運行rake ts：index或rake ts：configure時得到這個錯誤。我不記得我嘗試過的所有事情 - 我發現的大部分解決方案都與舊版本的gem等有關。顯然，它不是我的define_index定義，我按照最新的思想 - 獅身人面像自述。

    define_index do

    validates :name, presence: true, length: { maximum: 50 } 
    validates :ftype, presence: true, length: { maximum: 50 } 
    validates :description, presence: true, length: { maximum: 100 }

define_index方法是在使用中的3.0.0版本之前思維獅身人面像。現在索引定義使用ThinkingSphinx::Index.define方法並駐留在app/indices/文件夾中，而不是模型文件。實際上，您已經有了新的定義，因此您可以從item.rb中刪除define_index代碼塊。
