Re URLs Have look at http://itekblog.com/django-url-dispatcher-routing-beginners-tutorial/ ... and bear in mind that the 'r' and the '^' are not directly related and serve two purposes.
The very basic "overview" of Django is that urls point to views; views typically make use of models (and other bits-and-pieces such as forms or business logic code) to help handle data going in and/or out; and models are mapped to tables in your database (and themselves have code to help ensure data integrity). Very logical and not *too* hard! Without those layers, your web app ends up being a huge mish-mash of code and data and HTML ... like "old skool" PHP. Easy to start off, but a nightmare to maintain as it gets more complex. Derek On Saturday, 20 July 2013 17:17:06 UTC+2, Randy Baxley wrote: > > The Django tutorial is not quite making it for me.
