Django Authorization

Definition

Authorization in Django is the process of verifying what an authenticated user is allowed to do (permissions, roles, and ownership).

Why It Matters

Authentication says “I am Alice”; Authorization says “Alice is allowed to edit this specific post but not that one.” Without robust authorization, even a secure login system remains vulnerable to data leaks and unauthorized manipulation.

Core Concepts

• Permissions: Flags assigned to users or groups (e.g., can_add_log).
• Decorators: @login_required ensures a user is logged in.
• Ownership Checks: Logical checks in views to ensure a user can only access their own data.

from django.contrib.auth.decorators import login_required
from django.http import Http404

@login_required
def edit_entry(request, entry_id):
    """Edit an existing entry."""
    entry = Entry.objects.get(id=entry_id)
    # Authorization check: Ensure entry belongs to user
    if entry.topic.owner != request.user:
        raise Http404
    # ... logic to edit entry
