生成mongoid数据库配置文件
rails generate mongoid:config
create config/mongoid.yml
在这里不对mongoid.yml进行任何更改（假设已安装MongoDB并以默认设置启动），顺便贴一下生成的mongoid.yml 的文件内容
development:
# Configure available database sessions. (required)
sessions:
# Defines the default session. (required)
default:
# Defines the name of the default database that Mongoid can connect to.
# (required).

使用scaffold脚手架生成测试程序
rails generate scaffold User name:string email:string
invoke mongoid
create app/models/user.rb
invoke resource_route
route resources :users
invoke scaffold_controller
create app/controllers/users_controller.rb
invoke erb
create app/views/users
create app/views/users/index.html.erb
create app/views/users/edit.html.erb
create app/views/users/show.html.erb
create app/views/users/new.html.erb
create app/views/users/_form.html.erb
invoke helper
create app/helpers/users_helper.rb
invoke jbuilder
create app/views/users/index.json.jbuilder
create app/views/users/show.json.jbuilder
invoke assets
invoke coffee
create app/assets/javascripts/users.js.coffee
invoke scss
create app/assets/stylesheets/users.css.scss
invoke scss
create app/assets/stylesheets/scaffolds.css.scss
顺便也贴一下生成的model文件 user.rb
class User
include Mongoid::Document
field :name, type: String
field :email, type: String
end
运行测试服务器
rails server
=> Booting WEBrick
=> Rails 4.0. application starting in development on http://0.0.0.0:3000
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server
[-- ::] INFO WEBrick 1.3.
[-- ::] INFO ruby 2.0. (--) [x86_64-linux]
[-- ::] INFO WEBrick::HTTPServer#start: pid= port=
访问地址http://localhost:3000/users 并添加一条数据
运行mongo查看数据是否添加成功
mongo
MongoDB shell version: 2.4.
