django-pgcrypto

I recently wrote some python (and Django) utilities for working with pgcrypto. Includes a fun pure python implementation of ASCII Armor format – http://www.ietf.org/rfc/rfc2440.txt

GzipFileSystemStorage

I just posted a snippet for a Django file storage backend that transparently compresses files using the gzip python module. Nothing fancy, but it gets the job done, with a few caveats:

Many-To-Many Subsets

I'm modeling game results in a Django app I'm working on. A team consists of one or more players, and players may be on multiple teams – a ManyToManyField in Django. Then there are locations that maintain a list of players (not teams) who are authorized to play there, and players may be authorized for multiple locations – another ManyToManyField. What I wanted to find was, given a location, a list of teams whose players are all authorized to play at that location.

I posted a snippet containing the code I wrote to accomplish this. Basically, it's just some convenience code to avoid having to drop down to SQL or use triggers for the simple case of having a model where you want certain fields to be full-text searchable. A SearchableModel will, by default, automatically update it's search index when you call its save() method. The API is documented at the top of the snippet, so I won't duplicate it here, but I will share the search view this site uses:

FastCGI, et. al.

I've been wanting to drop mod_python since the day I installed it. After the saga of setting it up, I was left feeling unclean. So I sat down yesterday and started downloading new versions of stuff. Apache, mod_fastcgi, Python, Subversion, PHP… you name it. My biggest concerns were upgrading to Python 2.5, and switching this site (and others) from mod_python to mod_fastcgi. But I sure am glad I did. Deploying a Django site was never my favorite thing to do under mod_python, but with mod_fastcgi, it became an almost joyous experience.
