Tracking dirty fields on a Django model instance.
Dirty means that field in-memory and database values are different.

This package is compatible and tested with the following Python & Django versions:

Install
=======

.. code-block:: bash

    $ pip install django-dirtyfields


Usage
=====

To use ``django-dirtyfields``, you need to:

- Inherit from ``DirtyFieldsMixin`` in the Django model you want to track.

.. code-block:: python

    from django.db import models
    from dirtyfields import DirtyFieldsMixin

    class ExampleModel(DirtyFieldsMixin, models.Model):
        """A simple example model to test dirty fields mixin with"""
        boolean = models.BooleanField(default=True)
        characters = models.CharField(blank=True, max_length=80)

- Use one of these 2 functions on a model instance to know if this instance is dirty, and get the dirty fields:

  * ``is_dirty()``
  * ``get_dirty_fields()``


Example
-------

.. code-block:: python

    >>> model = ExampleModel.objects.create(boolean=True,characters="first value")
    >>> model.is_dirty()
    False
    >>> model.get_dirty_fields()
    {}

    >>> model.boolean = False
    >>> model.characters = "second value"

    >>> model.is_dirty()
    True
    >>> model.get_dirty_fields()
    {'boolean': True, "characters": "first_value"}
