In addition, the code takes advantage of some of the methods available for an association. We use the +create+ method on +@post.comments+ to create and save the comment. This will automatically link the comment so that it belongs to that particular post.
-Once we have made the new comment, we send the user back to the original post using the +post_path(@post)+ helper.
