$ pip install django-dirtyfields


To use django-dirtyfields, you need to:

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

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()


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

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

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