未初始化的常量Mongoid :: Spacial :: Document :: ClassMethods :: Mongo

Question

I am trying to use mongoid_spacial gem and here is how my model looks:

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

The error is

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`

Any help is appreciated.

升级到mongoid_spacial 0.2.17，它修复了您看到的命名空间错误 。
