前言

使用 Ruby 处理各种任务时难免会和数据库打交道，而 MongoDB 又是一款应用极其广泛的数据库

RubyGems 是 Ruby 的武器库，类似于 Perl 的 CPAN，各类封装好的处理逻辑应有尽有，我们可以充分利用这些成品包来减轻开发的工作量，其中 mongo 的 gem 就可以很好地满足我们的需求

A Ruby driver for MongoDB
The MongoDB Ruby driver is the officially supported Ruby driver for MongoDB. It’s written in pure Ruby and is optimized for simplicity. It can be used on its own, but it also serves as the basis of several object mapping libraries

这里我分享一下使用 Ruby 来操作 MongoDB 数据库的相关基础，详细可以参考 Ruby Driver Tutorial

Tip: 当前的最新版本为 mongo 2.2.5
