模式复杂的mongodb批插入

Question

我一直在网上寻找解决我的问题的方法。我正在使用Mongoid写一组数据到MongoDB。

我试图做一个批量插入与mongoid如下:

class Geonode
  include Mongoid::Document
  include Mongoid::Timestamps
  embeds_one :location
  embeds_one :transport
end
class Location
  include Mongoid::Document
  field :city,        :type => String
  embedded_in :geonode
end
class Transport
  include Mongoid::Document
  embeds_many :trainstation
  embedded_in :geonode
end
class Trainstation
  include Mongoid::Document
  field :station, :type => String
  belongs_to :transport
end

一个一个地做很好，但如果我想批量处理很多，我该怎么做?

我试过了。

require 'moped'
require 'rubygems'
require 'mongo'
require 'mongoid'
require 'skySchema.rb' #schema is the file i defined the classes just before

Mongoid.load!("./mongoid.yml", :development)
include Mongo
batch = []
batch << {:location => Location.new(:city => "London"),
          :transport => Transport.new(:trainstation => 
           [Trainstation.new(:station => "Kings Cross")])}}
and then doing this many many times, after which 
Geonode.collection.insert(batch)

但它不起作用。我做错什么了吗?

问题是，对于批量插入，您需要做:

Geonode.insert(batch)

并以不同的方式格式化批处理。现在一切都好了。谢谢大家的帮助。
