PySIG Notes, 23-Sept-2010, Bill Freeman and Django

Seven folks attended the September meeting of the Python Special Interest Group of the Greater New Hampshire Linux User Group held as usual on the 4th Thursday of the month at the Amoskeag Business Incubator in Manchester. Bill Sconce, PySIG’s organizer, supplied milk and Janet supplied (excellent!) chocolate chip cookies.

Bill Freeman was the presenter for the night, and spoke about Django. Django is a web framework written in Python. It supports the WSGI web server gateway interface specification which allows a standard way of connecting to web servers and provides facilities to “stack” additional WSGI-compliant applications to act as filters, caches, security modules, etc. between the web server and your application. Bill walked through the flow of data through the application’s architecture from http request, through parsing, views and the template language, processing in the ORM and out as the http response. There are hooks galore where you can add your own code, modifying the flow of data and responses. Django is a world-class web framework, with facilities to plug in additional “engines” — mini-applications — and add your own template tags, customize the automated generate of the data schema, and of course, write your own application logic. It’s Open Source, it’s Python, and the code is there for you to mess with. Django’s most popular add-on provdes an administrative function that provides developers (and, optionally, their customers) with simple add/edit/delete forms. Django seems to be a platform well worth considering if you’re interested in web apps in Python. Bill’s slides are available on the GNHLUG wiki.

Thanks to Bill Freeman for a great presentation, to Bill Sconce for organizing the meeting, to Janet for the awesome cookies, and to the Amoskeag Business Incubator for providing the fine facilities.
