Project Description

django-modeldict

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).

It was originally created by Disqus, but due to the inactivity we at YPlan have taken over maintenance on this fork.

Requirements

Tested with all combinations of:

  • Python: 2.7, 3.5
  • Django: 1.8, 1.9, 1.10

Install

Install it with pip:

pip install django-modeldict-yplan

Make sure you pip uninstall django-modeldict first if you’re upgrading from the original to this fork - the packages clash.

Example Usage

# You'll need a model with fields to use as key and value in the dict
class Setting(models.Model):
    key = models.CharField(max_length=32)
    value = models.CharField(max_length=200)

# Create the ModelDict...
settings = ModelDict(Setting, key='key', value='value', instances=False)

# And you can treat it like a normal dict:

# Missing values = KeyError
settings['foo']
>>> KeyError

# Sets supported
settings['foo'] = 'hello'

# Fetch the current value using normal dictionary access
settings['foo']
>>> 'hello'

# ...or by normal model queries
Setting.objects.get(key='foo').value
>>> 'hello'

Pending release

  • New release notes here

1.5.4 (2016-10-28)

1.5.3 (2016-09-20)

  • Stop rounding time.time() down to the nearest integer, so we are more fine grained around expiration. It might also fix a subtle timing bug around re-fetching the remote cache unnecessarily.

1.5.2 (2016-07-31)

  • Fixed update missing when _local_last_updated could be set even when it wasn’t updated
  • Fixed update missing from integer rounding in time comparison
  • Fixed CachedDict.__repr__ so it works for other subclasses of CachedDict than ModelDict (don’t assume self.model exists)

1.5.1 (2016-06-13)

  • Fixed local cache never expiring if value was checked too often.
  • Use Django’s cache.set_many for more efficient storage.

1.5.0 (2016-01-11)

  • Forked by YPlan
  • Fixed concurrency TOCTTOU bug for threaded Django servers.
  • Stopped including the ‘tests’ directory in package
  • Django 1.8 and 1.9 supported.
  • Python 3 support added.
  • Fixed setdefault() to return the value that was set/found, as per normal dict semantics. Thanks @olevinsky.
