I found what I think is a slick solution to a problem of mine but I’d
like to know if there is a better way to accomplish what I did.
I have 2 tables:
category # can be either ‘ADMIN’, ‘AUDITOR’ or ‘TENANT’
I need the audits to belong to both an AUDITOR and a TENANT user:
class User < ActiveRecord::Base
class Audit < ActiveRecord::Base
belongs_to :user # !!! This does not work even using :class_name,
After tinkering for a while with it I couldn’t find an easy way of
making it work. Then I had an idea that has worked and I think is
pretty slick. I created 3 models:
class Admin < User
Admin specific functionality here
class Auditor < User
Auditor specific functionality here
class Tenant < User
Tenant specific functionality here
When a user is retrieved for access and functionality validations, I
re-retrieve the user through the specific user class as in:
user = User.find(…)
The user is found and passes validations.
Now I re-retrieve it through the specific user class based in the
user = user.category.capitalize.constantize.find(user.id) if user
From that moment on I have the user retrieved through its correct type
and my associations work wonderfully.
Is there a better way of making this work?
