Rails 4:一起使用MySql和MongoDB [英] Rails 4: Use MySql and MongoDB together
问题描述
我正在尝试使用MongoDB(mongoid)和MySQL一起在Rails 4中创建一个应用程序. 但是我无法设置它.
I'm trying to make an application in rails 4 using MongoDB(mongoid) and MySQL together. But I'm not able to set it up.
我正在执行以下步骤:
-
rails new myapp -d mysql
- 然后将这些行添加到Gemfile中:
gem "mongoid"
gem "bson_ext"
-
bundle install
-
rails g mongoid:config
rails new myapp -d mysql
- Then added these lines to Gemfile:
gem "mongoid"
gem "bson_ext"
bundle install
rails g mongoid:config
步骤4失败.我无法解决问题.它显示以下错误.
The step 4 fails. I'm not able to figure out the problem. It shows the following error.

我正在关注一些细节:
- 操作系统-ubuntu 14.04
- 红宝石v2.2.2
- 导轨4.2.3
推荐答案
将以下行添加到您的application.rb
文件中:
config.generators do |g|
g.orm :active_record
end
add these line to your application.rb
file:
config.generators do |g|
g.orm :active_record
end
这将迫使rails g使用活动记录.
This will force rails g to use active record.
每当要为mongodb生成模型时,请使用:
rails g mongoid:model yourmodelname
And whenever you want to generate a model for mongodb, use:
rails g mongoid:model yourmodelname
