[Francisco Souza] Flying with Flask on Google App Engine

A little late, finally I introduce the third part of using Python frameworks in Google App Engine. I wrote before about web2py and Django, and now is the time of Flask, a Python microframework based on Werkzeug, Jinja2 and good intentions. Unlike Django and web2py, Flask is not a full stack framework, it has not a database abstraction layer or an object relational mapper, Flask is totally decoupled from model layer. It is really good, because we can use the power of SQLAlchemy (which is, IMHO, the best ever data abstraction framework =P) when we are working with relational databases, and when work with non-relational databases, we can use the native API.
