如何从现有的Rails 4应用程序中删除ActiveRecord?

问题描述：

我开始了一个Ruby on Rails项目，该项目包括一个带有ActiveRecord和Neography的简单推荐系统.现在，我发现了有关 neo4j.rb 的信息，这将大大简化我的生活. :-)

I started off a Ruby on Rails Project which includes a simple recommender system with ActiveRecord and Neography. Now I found out about neo4j.rb, which is going to simplify my life by a lot. :-)

到现在为止，我了解到，可以在没有ActiveRecord的情况下创建新的应用程序，如下所示:

I learned by now, that I could create a new Application without ActiveRecord as follows:

rails new xyz -O

我可以这样做，然后将我的大多数文件/代码复制粘贴到该新项目中.还是有更简单的方法?

I could do that and copy paste most of my files / code into that new project. Or is there an easier way?

我仍在考虑该步骤是否必要.是否可以同时使用neo4j.rb和ActiveRecord?我正在考虑在Neo4j中使用ActiveRecord和我的推荐系统运行身份验证系统(例如Devise).有没有人有使用这种方法的经验?

I am still thinking about if that step is even necessary. Is it possible to use both neo4j.rb and ActiveRecord in parallel? I am thinking of running the authentication system (e.g. Devise) with ActiveRecord and my recommender system in neo4j. Does anyone have experiences with such an approach?

答

执行以下步骤

从Gemfile中删除数据库适配器gem，例如mysql2，sqlite3等

Remove database adapter gems from your Gemfile, e.g., mysql2, sqlite3, etc

从application.rb中删除require 'rails/all'并需要框架(在这些

From application.rb, remove require 'rails/all' and require frameworks (among those available in your rails version, the list varies, do not just copy) you want to use, for example:

require "action_controller/railtie"
require "action_mailer/railtie"
require "sprockets/railtie"
require "rails/test_unit/railtie"

删除database.yml，schema.rb和所有迁移

Delete database.yml, schema.rb and all the migrations

希望这会有所帮助！
