如何添加的ActiveRecord到一个Rails应用程序没有ActiveRecord的初始化？ [英] How do I add ActiveRecord to a rails app initialized without ActiveRecord?

问题描述

我创建了-O选项（即没有ActiveRecord的）一个Rails应用程序。但现在我想主动记录添加到它。我怎样才能实现这个目标？

I created a rails app with the -O option (i.e. without ActiveRecord). But now I want to add active record to it. How can I accomplish that?

推荐答案

在配置/ application.rb中，你应该看到的 ActiveRecord的 railtie被注释掉了（见下文）。

Inside of config/application.rb you should see where the ActiveRecord railtie is commented out (see below).

# Pick the frameworks you want:
# require "active_record/railtie"
require "action_controller/railtie"
require "action_mailer/railtie"
require "active_resource/railtie"
require "sprockets/railtie"
require "rails/test_unit/railtie"

取消注释了。

Uncomment it.

另外，还要确保到的database.yml 文件和数据库适配器宝石（如 sqlite3的）添加到您的Gemfile。

Also make sure to add a database.yml file and the a database adapter gem (e.g. sqlite3) to your Gemfile.
