 Additionally, utilizing triggers for model history tracking in Django promotes data integrity and compliance with auditing requirements. By maintaining a comprehensive record of changes, developers can trace back and analyze the evolution of data, helping to identify potential issues, perform forensic analysis, or meet regulatory obligations.
 
-In this talk, we show how to implement history tracking using [django-pghistory](hub.com/opus10/django-pghistory), an app that uses Postgres triggers to track historical changes. We discuss the philosophy of django-pghistory and how it models historical changes so that engineers can use structured history tables that mirror tracked models. We show how users can attach free-form context from the application to group together changes, forming a more coherent audit trail. We also discuss several other application-specific examples of using django-pghistory in practice, for example, using conditional history triggers to track and snapshot specific events.
