Cached model property decorator (like @property)

This is a nice decorator for using the cache to save the results of expensive-to-calculate but static-per-instance model properties. There is also a decorator for when the property value is another model, and the contents of the other model should not be cached across requests. 3 levels of caching implemented: * outermost: django cache * middle: obj._cache (for multiple properties on a single object) * innermost: replace the attribute on this object, so we can entirely avoid running this function a second time.

Decorate every view in a url tree

Add login_required (or any other combination of decorators) to any view references by the urls created by patterns(...). My personal little itch as an example... urlpatterns += required( login_required, patterns('', (r'^api/', include(api.urls)), ) )

Active Directory Authentication Backend (with User object updating)

I used the code from http://djangosnippets.org/snippets/901/ and expanded the code to have the possibility to map AD groups to the superuser attribute of Django's users. The code updates the Django users database every time a user connects, so every change in the AD is replicated to the Django database.

staff_or_404 Decorator

Sometimes I don't want to reveal a staff-only view so I created this decorator, using ``django.contrib.admin.views.decorators.staff_member_required`` as my boilerplate. Non staff members are kicked to the 404 curb. Suggestion: Create a file, ``decorators.py`` in your project (or single app) and import like so: ``from myproject.app_name.decorators import staff_or_404``.

Updated: GeoJSON Serializer for GeoDjango (gis)

Unfortunately the built in Django JSON serialzer encodes GeoDjango GeometyrField as WKT text. This snippet extends django's serializer and adds support for GEOJson format. Built in JSON serializer output: [{"pk": 1, ... "geopoint": "POINT (-76.5060419999999937 44.2337040000000030)" ... }] GeoJSON serializer ouput: [{"pk": 1, ... "geopoint": {"type": "Point", "coordinates": [-76.503296000000006, 44.230956999999997], "__GEOSGeometry__": [ "__init__", [ "SRID=4326;POINT (-75.5129950000000036 44.2442360000000008)" ] ] }] Note: the "__GEOSGeometry__" is a class hint as defined by JSON-RCP and used during deserilization.
