        "description": "===================\nDjango Dirty Fields\n===================\n\nTracking changed fields on a Django model instance.\n\nMakes a Mixin available that will give you the properties:\n\n * ``is_dirty``\n * ``dirty_fields``\n\n\nInstalling\n==========\n\nInstall the package using pip_. Then use the instructions in \"Using the Mixin in the Model\".\n\n::\n\n    $ pip install django-dirtyfields\n\nor if you're interested in developing it, use virtualenv_. The default ``settings.py`` will look for the dirtyfields package in its current location.\n\n::\n\n    $ virtualenv --no-site-packages ve/\n    $ source ve/bin/activate\n    (ve)$ cd example_app\n    (ve)$ pip install -r requirements.pip\n    (ve)$ ./manage.py test testing_app\n\n\n.. _pip: http://www.pip-installer.org/en/latest/\n.. _virtualenv: https://pypi.python.org/pypi/virtualenv\n\n\n\nUsing the Mixin in the Model\n============================\n\n::\n\n    from django.db import models\n    from dirtyfields import DirtyFieldsMixin\n\n    class TestModel(DirtyFieldsMixin, models.Model):\n        \"\"\"A simple test model to test dirty fields mixin with\"\"\"\n        boolean = models.BooleanField(default=True)\n        characters = models.CharField(blank=True, max_length=80)\n\n\nUsing it in the shell\n=====================\n\n::\n\n    (ve)$ ./manage.py shell\n    >>> from testing_app.models import TestModel\n    >>> tm = TestModel(boolean=True, characters=\"testing\")\n    >>> tm.save()\n    >>> tm.is_dirty\n    False\n    >>> tm.dirty_fields\n    ()\n    >>> tm.boolean = False\n    >>> tm.is_dirty\n    True\n    >>> tm.dirty_fields\n    ('boolean', )\n    >>> tm.characters = \"have changed\"\n    >>> tm.is_dirty\n    True\n    >>> tm.dirty_fields\n    ('boolean', 'characters', )\n    >>> tm.save()\n    >>> tm.is_dirty\n    False\n    >>> tm.get_dirty_fields\n    ()\n\nWhy would you want this?\n========================\n\nWhen using signals_, especially pre_save_, it is useful to be able to see what fields have changed or not. A signal could change its behaviour depending on whether a specific field has changed, whereas otherwise, you only could work on the event that the model's `save()` method had been called.\n\nCredits\n=======\n\nThis code has largely be adapted from what was made available at `Stack Overflow`_.\n\n.. _Stack Overflow: http://stackoverflow.com/questions/110803/dirty-fields-in-django\n.. _signals: http://docs.djangoproject.com/en/1.2/topics/signals/\n.. _pre_save: http://docs.djangoproject.com/en/1.2/ref/signals/#django.db.models.signals.pre_save",
