``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 <https://github.com/disqus/django-modeldict>`_, but due to the inactivity we at YPlan have taken over maintenance on this fork.

Requirements
------------

Tested with all combinations of:

* Python: 3.6
* Django: 1.11, 2.0, 2.1

Python 3.4+ supported.

Install
-------

Install it with **pip**:

.. code-block:: bash

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
-------------

.. code-block:: python

# 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
---------------

.. Add new release notes below here

2.0.1 (2019-02-15)
------------------

* No functional changes. This is a re-release of version 2.0.0 to fix immutable
metadata on PyPI so that Pip on Python 2 doesn't pick up the Python 3 only
2.X series. **Version 2.0.0 will be pulled from PyPI on 2019-02-29.**

2.0.0 (2019-01-29)
------------------

----

**This version is due to be pulled from PyPI, please use version 2.0.1 as per
its above release note.**

----

* Drop Python 2 support, only Python 3.4+ is supported now.
* Drop Django 1.8, 1.9, and 1.10 support. Only Django 1.11+ is supported now.
* Remove ``iteritems()``, ``iterkeys()``, and ``itervalues()`` methods from
``ModelDict``, and move ``items()``, ``keys()``, and ``values()`` to Python 3
semantics, returning iterators rather than lists.
* Include LICENSE file in wheel.
* Tested with Django 2.1 (no changes were needed for compatibility).

1.5.4 (2016-10-28)
------------------

* Fixed a race condition in threaded code. See https://github.com/adamchainz/django-modeldict/pull/40 for a detailed
explanation. Thanks @Jaidan.

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.

1.4.1 (2012-12-04)
------------------

* Last release by Disqus
