我正在尝试结合使用 MongoDB(mongoid) 和 MySQL 在 Rails 4 中创建一个应用程序。
但我无法设置它。
我正在按照以下步骤操作：
rails new myapp -d mysql- 然后将这些行添加到 Gemfile 中：
gem "mongoid"
gem "bson_ext"
bundle installrails g mongoid:config
步骤 4 失败。我无法找出问题所在。它显示以下错误。

我正在关注这个url https://sachkadam.wordpress.com/2013/05/03/setup-a-rails-app-to-use-both-mongodb-and-mysql-together/.
一些细节：
- 操作系统-ubuntu 14.04
- 红宝石 v2.2.2
- 导轨 4.2.3
将这些行添加到您的application.rb file:
config.generators do |g|
g.orm :active_record
end
这将强制 Rails g 使用活动记录。
每当您想为 mongodb 生成模型时，请使用：
rails g mongoid:model yourmodelname
