Rails 4设计多个用户模型STI [英] Rails 4 Devise Multiple User Models STI

问题描述

感谢您的阅读。

我正在使用Devise和Rails 4.我想添加多个用户模型（admin，usertype1，usertype2），以便它们继承自主要用户模型我搜索了很多帖子，得出结论，我可以使用CanCan，我不想要，或者我可以使用单表继承。

我看到的方式是将类型字符串列添加到我使用Devise创建的主用户模型。我还需要从父级扩展每个子类，如：

  class Admin<用户
 end 
 
 class Usertype1<用户
 end 
 
 class Usertype2<用户
结束
  

我的问题是：下一步该怎么办？我如何知道如何访问类型列？我还需要覆盖 current_user 帮助器方法的Devise控制器，以便我可以使用 current_admin ？

再次感谢

解决方案

您还可以使用easy_roles宝石。它可以在github上使用。这个宝石为您的不同用户角色提供了一个bitmask解决方案。你只需要有一个模型，例如User，这个模型得到一个属性role。只需检查github上的文档。
Devise + easy_roles + CanCan是一个非常好的设置，在我看来非常方便。我经常使用这个。

Thanks for reading.

I am using Devise and Rails 4. I want to add multiple User Models(admin, usertype1, usertype2) such that they inherit from the main User Model. I have searched many posts and come to the conclusion that I may use CanCan, which I do not want, or I may use Single Table Inheritance.

The way I see it is to add a type string-column to my main User model I created with Devise. I will also need to extend each sub-class from the parent as in:

class Admin < User
end

class Usertype1 < User
end

class Usertype2 < User
end

My question is: what do I do next? How exactly do I know how to access the type column? Do I also need to override the Devise Controller for the current_user helper method such that I can have current_admin for example?

Thanks again.

解决方案

You can also use the easy_roles gem. It is available on github. This gem provides a bitmask solution for your different user roles. You just must have one model, e.g User, this model gets an attribute "role". Just checkout the docs on github. Devise + easy_roles + CanCan is a very good setup, it is very convenient in my opinion. I use this quite often.
