Multi Table Inheritance with rails 3

Question

Are there standards or best practices yet when it comes to multi table inheritance in rails 3? So far the best article I could find was:

http://mediumexposure.com/multiple-table-inheritance-active-record/

But even that needed some changes(e.g. moving the requires to an initializer instead of the old /config/environment.rb)

Any better resources / standards?

Answer 1

For an easy way to do multi-table inheritance take a look at 'acts_as_relation' plugin https://github.com/hzamani/acts_as_relation.

Answer 2

I recently forked a promising gem to implement multiple table inheritance and class inheritance in Rails. I have spent a few days subjecting it to rapid development, fixes, commenting and documentation and have re-released it as CITIER (Class Inheritance and Table Inheritance Embeddings for Rails).

Consider giving it a look: https://github.com/PeterHamilton/citier

It actually takes some concepts from that article you mention.
