Ruby Developer Interview Question:

Tell me what is Polymorphic Association in Ruby on Rails?

Submitted by: Muhammad

Polymorphic Association allows an ActiveRecord object to be connected with Multiple ActiveRecord objects. A perfect example of Polymorphic Association is a social site where users can comment on anywhere whether it is a videos, photos, link, status updates etc. It would be not feasible if you have to create an individual comment like photos_comments, videos_comment and so on.
