django-modeldict-rc 1.3.1

ModelDict is a very efficient way to store things like settings in your database. The entire model is transformed into a dictionary (lazily) as well as stored in your cache. It’s invalidated only when it needs to be (both in process and based on CACHE_BACKEND).

Quick example usage. More docs to come (maybe?):

class Setting(models.Model):
    key = models.CharField(max_length=32)
    value = models.CharField(max_length=200)
settings = ModelDict(Setting, key='key', value='value', instances=False)

# access missing value
settings['foo']
>>> KeyError

# set the value
settings['foo'] = 'hello'

# fetch the current value using either method
Setting.objects.get(key='foo').value
>>> 'hello'

settings['foo']
>>> 'hello'
