A Comment can be related to any other model.
For example Event 123 could have a comment which would look like this:
INSERT INTO comments ('class','foreign_id','name','body') VALUES
('Event',123,'title','comment body');
Or Post 456 may have a comment which would look like this:
INSERT INTO comments ('class','foreign_id','name','body') VALUES
('Post',456,'another title','another comment body');
When you define the foreign_id in the Post or Event model, this is
used for finding data, not for saving data.
In order to save the comment to the right record you need to define a
Comment.class and Comment.foreign_id.
Hope this helps to explain it.
