An introduction to Django Simple History

Wouldn’t it be useful if we could document changes in our life and revisit them later at will? It would allow us to better analyze situations, remember what we were thinking, or help us remember how we got to our current state. Although no such tool currently exists for changes in life, one such tool does exist in Django. It is called django-simple-history.

Django-simple-history stores Django model state on every create, update, or delete database operation; it can even revert back to old versions of a model, record which user changed a model, interact with multiple databases, and more. Rather than making code changes, django-simple-history gives us the ability to view and perform many of the changes via the admin interface.

Let’s imagine we are creating a simple Polling application and our models.py file looks like this:

from django.db import models

class Poll(models.Model):
    question = models.CharField(max_length=200)
    pub_date = models.DateTimeField('date published')
    published = models.BooleanField(default="False")

    def __str__(self):
        return self.question

How do we get django-simple-history to work on our application
