ContentType Form

When working with the ContentType model there are generally two issues. 1. Models are listed in the table but not imported. 2. Unicode only returns model not application so being able to select a a app/model is sometimes difficult when to applications have a model with the same name. This snippet gets a listing of imported models and creates a drop down for selection. I also included a function that uses the returned from to get and save the correct ContentType within the primary model.

Now you can get 'today', 'yesterday', 'tomorrow' or '2009/9/10 11:56'

create and authenticate an anonymous user

If you want anonymous visitors to your site, or parts of your site to be authenticated as real users so that you can treat them as such in your views and models, use this snippet. Add the above AuthenticationBackendAnonymous middleware into AUTHENTICATION_BACKENDS in your settings.py and use the snippet anonymous_or_real(request) in your views, which returns a user. Comment out the bit where it creates a profile if you are not using profiles.

Conditional Caching

HTTP Authorization Middleware/Decorator

Use HTTP Authorization to log in to django site. If you use the FORCE_HTTP_AUTH=True in your settings.py, then ONLY Http Auth will be used, if you don't then either http auth or django's session-based auth will be used. This assumes that the regular auth middleware is already installed. If you provide a HTTP_AUTH_REALM in your settings, that will be used as the realm for the challenge. Having both a decorator and a middleware means that for site-wide http auth, you only need to specify it once, but the same code can be used as a decorator if you want part of your site protected using htty basic auth, and the other bits freely visible. Of course, since this is basic auth, then you need to make sure your site is running under SSL (HTTPS), else your users passwords are effectively transmitted in the clear.
