Configure Rails 4, MongoDB, Cucumber, Capybara

Question

我目前正在设置我的第一个Mongodb，Rails 4环境，需要在运行捆绑安装之前配置gem。这是我的宝石文件。

source 'https://rubygems.org'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.0.1'
# User mongoid for database.
gem 'mongoid', github: 'mongoid/mongoid'
# Use SCSS for stylesheets
gem 'sass-rails', '~> 4.0.0'
# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '>= 1.3.0'
# Use CoffeeScript for .js.coffee assets and views
gem 'coffee-rails', '~> 4.0.0'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', platforms: :ruby
# Use jquery as the JavaScript library
gem 'jquery-rails'
# Turbolinks makes following links in your web application faster. Read more:      https://github.com/rails/turbolinks
gem 'turbolinks'
# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder
gem 'jbuilder', '~> 1.2'
group :doc do
# bundle exec rake doc:rails generates the API under doc/api.
gem 'sdoc', require: false
end
group :test do
  gem 'cucumber-rails', :require => false
  gem 'capybara'
  #database_cleaner is not required, but highly recommended
  gem 'database_cleaner'
end

似乎Mongo

不会安装，因为我找不到Mongo：Config文件。

Answer 1

通过运行以下命令生成配置文件：

rails g mongoid:config

请阅读mongoid文档，它非常好。
