Frontend design
Model-View-Controller (MVC) design pattern
• Supported by Django
• The model is the information held by the application
(stored in a database as tables of legislation, user
accounts, discussion threads, etc).
• The view is the user interface that presents the
information in the model.
• The controller responds to user interactions with the view
and updates the view and model accordingly.
Backend design
Will periodically run a Django script with cron that:
• Grabs web pages from Senate.gov, etc
• Parses them with lxml
• Interprets the data and adds new data to the database
Resources
There are numerous prebuilt Django applications:
• django-authopenid
• django-registration
• django-voting
• django-forum
• django-graphs
• django-yacaptcha
