Django Auth Database Schema Diagram
Django's built-in auth app creates a set of authentication tables when you run migrate: auth_user, auth_group, auth_permission, plus the many-to-many join tables auth_user_groups, auth_user_user_permissions, and auth_group_permissions. This diagram maps the full schema - including how permissions link to content types through django_content_type, and how admin actions are logged in django_admin_log.

Frequently asked questions

How do Django users relate to groups and permissions?
Users relate to groups through the auth_user_groups join table and to permissions through auth_user_user_permissions. Groups relate to permissions through auth_group_permissions. All three are many-to-many relationships.
