Understanding Permissions in Django and Access Control Across Modules

Django’s built-in authentication and authorization system is a cornerstone of its security framework, allowing developers to manage user permissions with precision. Permissions control what actions users can perform on your application’s data, ensuring security and compliance. In this guide, we’ll explore how permissions work across Django’s modules, clarify common misconceptions, and provide actionable examples for implementation.

What Are Permissions in Django?

Permissions in Django are rules that determine whether a user can perform specific actions on a model. By default, Django creates three permissions for every model you define:

1. Add (add_<modelname>): Grants the ability to create new instances of the model.
2. Change (change_<modelname>): Allows modification of existing model instances.
3. Delete (delete_<modelname>): Enables deletion of model instances.

Starting in Django 2.1, developers can optionally include a View permission (view_<modelname>) by explicitly defining it in the model’s Meta class. This is not enabled by default, so you must configure it manually if needed.
