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
iPhone Web App Links
I was working on an iPhone web app recently (my first, actually) and came across an annoyance: any links in a web app with apple-mobile-web-app-capable set to "yes" will open in Safari, not the app itself. I wanted to keep things as simple as possible, and not have to change my code to support AJAX loading. Some research turned up this article which did almost exactly what I wanted, except I didn't want to load a page into a container. I wanted all links to Just Work how you'd expect links to work. So I dropped this bit of jQuery code into my base template, and everything seems to work great:
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.
Searchable Models
If you happen to be one of about 4 people that actually reads this, you may notice I added a search box to the sidebar. What's far more interesting is the code behind it. 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:
