Django Debugging Guide

Overview

Django debugging requires understanding the framework's layered architecture: settings, URL routing, views, templates, models, and middleware. Effective debugging follows a systematic approach - reproducing the bug, isolating the problem, gathering evidence, and implementing verified fixes.

Key principles:

• Reproduce first: Repeat the exact steps that cause the issue
• Isolate systematically: Identify the exact module, function, or code path
• Gather evidence: Collect error messages, stack traces, logs, and database state
• Test your fix: Verify the solution with automated tests

Common Error Patterns
