与 mongo-1.8.3、mongoid 3.1.2 一起使用 rails
我想组合许多字符串字段并创建一个全文索引.. 但在初始设置期间我收到此错误
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
在 rake db:create_indexes 上出现错误
rake aborted!
undefined method `db' for #<Moped::Collection:0x007fba5c768f18>
