我是rails和mongodb的新手。我已经在我的rails项目名称中生成了mongod模型作为论坛 当我尝试使用rails控制台中的以下命令添加记录时
f = Forum.new
f.topic_name = "my_topic"
f.save
我收到以下错误

a set #<Moped::Cluster:25470936 @seeds=[<Moped::Node resolved_address=nil>]>
我在端口27017上运行mongod服务器 以下是我的mongoid.yml文件

怎么做??
答案 0 :(得分:0)
查看您的hosts文件中的localhost映射,或尝试使用0.0.0.0:27017
作为主机。
