未初始化的常量Mongoid ::空間::文檔:: ClassMethods ::蒙戈

Question

我想使用mongoid_spacial寶石，這裏是我的模型的外觀：

 
class Place 
    include Mongoid::Document 
    include Mongoid::Spacial::Document 

     field :name, :type => String 

     field :source,   type: Array, spacial: true 
     field :mouth,    type: Array, spacial: {lat: :latitude, lng: :longitude, return_array: true } 

     spacial_index :source 

     end 

的錯誤是

 
    uninitialized constant Mongoid::Spacial::Document::ClassMethods::Mongo 
    MONGOID: Attempted to constantize Property, trying without namespacing. 
    MONGOID: Failed to determine model from app/models/property.rb: 
    NameError:uninitialized constant Mongoid::Spacial::Document::ClassMethods::Mongo` 

任何幫助表示讚賞。

升級到mongoid_spacial 0.2.17，修復了a namespacing bug you're seeing。
