assigning many partially deviant variables

This was a much better way of incrementing variables that only changed a small amount in name. deltab in #python also said I could have used tuples, but I'm not familiar with them yet, so I added this to a list of things to look into.

Basic HTTP Authentication

A patch (against django svn trunk [4649](http://code.djangoproject.com/browser/django/trunk/?rev=4649)) that allows users to log in with Basic HTTP Authentication i.s.o. login forms using some simple middleware (entire patch is ~50 lines). I was unaware of http://code.djangoproject.com/wiki/GenericAuthorization so I'm not sure about its usefulness in the long run. You can enable it by including 'django.contrib.auth.middleware.BasicAuthenticationMiddleware' in your MIDDLEWARE_CLASSES and then adding the following lines in your settings.py: BASIC_WWW_AUTHENTICATION = True WWW_AUTHENTICATION_REALM = "djangolures.com" Updated: See also http://code.djangoproject.com/ticket/3609 (patch now availble here as well).

Detect iPhone & Switch Template via render_to_response

A fast way to implement an iPhone template switcher, especially if you have a lot of existing views using the render_to_response() shortcut. This checks for the iPhone browser and then modifies the chosen template by adding -mobile to the html's file name. Check out [this more complete list of user agents](http://minidetector.googlecode.com/svn/trunk/minidetector/tests/mobile_useragents.txt) if you need to detect specific mobile devices.

Declaring django views like web.py views

I work a little with [web.py framework](http://webpy.org/) and I like a lot the view definition. For each view you define a class and in that class you can define two method, GET and POST. If the http request is a GET request the GET method will be called and if http request is a POST request the POST method is called. Then you can define common stuff in another method that could be called inside each method, and you have a class for each view.
