  - by Prairiedogg

  I'm in the processes of internationalizing an iPhone app - I need to make programmatic changes to certain views based on what the user's current locale is.

• Adding a generic image field onto a ModelForm in django

  - by Prairiedogg

  - by Prairiedogg

  I'm trying to reuse a group of Obj-C clases between iPhone applications. The values that differ from app to app have been isolated and I'm trying to figure out the best way to apply these custom values to the classes on an app-to-app basis.
