Django

What This Skill Does

The Django skill is a comprehensive technical assistant for OpenClaw designed to help developers build, debug, and optimize Django applications. It focuses on high-performance practices, preventing common ORM bottlenecks like N+1 queries, and enforcing security best practices to protect against common web vulnerabilities. Whether you are architecting a new project or optimizing a legacy codebase, this skill provides actionable advice on database management, request lifecycle handling, and secure authentication workflows.

Installation

To integrate this skill into your environment, run the following command in your terminal: clawhub install openclaw/skills/skills/ivangdavila/django

Use Cases

• Database Optimization: Automatically detect and refactor code causing N+1 queries using select_related and prefetch_related.
• Security Auditing: Review existing views and models to ensure protection against XSS, SQL injection, and CSRF vulnerabilities.
• Architecture Design: Determine the best strategy for handling async views in Django, managing custom signal logic, or designing complex migration paths.
• Error Resolution: Troubleshoot production-level issues, such as MultipleObjectsReturned exceptions or race conditions during atomic updates.

Example Prompts

1. "Analyze this Django queryset snippet and tell me if it will cause an N+1 query issue or if I should use prefetch_related."
2. "I am getting a 403 Forbidden error on my POST request, can you walk me through a checklist to ensure my form is handled correctly?"
3. "Show me how to perform an atomic increment on a model field using F() expressions instead of standard save methods."

Tips & Limitations

• Caching: Always remember that QuerySets are lazy. Iterating over them twice triggers multiple database hits; use list() to cache results if you need to perform multiple passes.
• Atomic Updates: Be aware that the update() method bypasses the save() method. This means signals won't fire and auto_now fields will not be updated automatically.
• Async Constraints: Django's ORM is fundamentally synchronous. If working in an async view, ensure you use sync_to_async to avoid runtime errors.
• Model References: To avoid circular dependency errors, always use string references for foreign keys (e.g., 'app.Model') rather than direct class imports.
