Implementing User Comments with SQLAlchemy

One of the most basic ways to keep the users of your web application engaged is to give them a space to write comments. These days, there are third-party services pretty much for everything, and comments is not an exception. Disqus and Facebook are popular services that allow you to embed comments into your site.

But what if you don't want to use an external service? In this article, I'm going to show you how I implement comments in Python, using the SQLAlchemy ORM and any of the database engines it supports. I'm going to start with an extremely simple approach, and then will go on to discuss a few advanced implementations with support for multiple levels of replies.
