我如何从 Ruby 代码连接到 mongodb？

Answer 1

首先，您必须安装 MongoDb gem:

gem install mongo

然后运行代码:

require 'rubygems'  # not necessary for Ruby 1.9
require 'mongo'
db = Mongo::Connection.new.db("mydb") # OR
db = Mongo::Connection.new("localhost").db("mydb") # OR
db = Mongo::Connection.new("localhost", 27017).db("mydb")
