Django, as a powerful web framework, provides a robust command-line interface called `django-admin` that streamlines various aspects of managing a Django project. These admin commands automate routine tasks, database management, and other essential operations, saving developers significant time and effort.
In this article, we will explore some of the most useful `django-admin` commands and how they can enhance your Django development workflow.
