This video answers (hopefully) a question that a viewer was asking, How can i use the same comments entity with different other entities using a single relationship, this is where a polymorphic relationship is used, and in the case of Symfony or Doctrine we use what's called inheritance mapping.

This video does the following:
Create A Comment, Post, Video and parent entity called Comment.
Setup the inheritance type and identifiers for the targets.
Create a comments for both Post and Video and fetching them.
