The site’s author, Will McGugan, wrote up a blog post describing his experience with turbogears here. He says he chose TurboGears partially because he had already worked with CherryPy and really liked it. Will made this remark after talking about SQLObject:
Incidently, I don’t like the way that Python ORMs specify the database schema as Python code. Since the schema doesn’t change when the application is running, I would prefer a simple xml definition that would be used by the ORM to dynamically build classes for each table that could be derived from in the model code.
I like this idea, but instead of writing XML, I would prefer to write SQL and have python parse that to build classes.
