mongoid_fulltext错误：create_indexes ...未定义的方法`DB”为＃<助力车::收藏

Question

使用导轨与蒙戈-1.8.3以来，mongoid 3.1.2

我想很多串场组合并创建一个full_text指数..但初始安装过程中我得到这个错误

我的模型看起来像这样： -

class User 
    include Mongoid::Document 
    include Mongoid::Timestamps 
    include Mongoid::FullTextSearch 

    field :name, type: String 
    fulltext_search_in :name 

混得耙分贝的错误：create_indexes

低于0.6的mongoid_fulltext版本与Mongoid 3（也就是Moped）不兼容。 更新mongoid_fulltext错误消失
