SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Pattern-based error handling for Django/DRF and React/TypeScript apps, enabling consistent, client-friendly responses across backend and frontend layers when database and runtime errors occur.

Core Features & Use Cases

  • Centralized DRF exception handler that maps database and permission errors to structured responses.
  • Race condition prevention patterns (optimistic updates with filter().update() and pessimistic select_for_update).
  • Savepoint handling for materialized views to guard transactions against missing views.
  • Frontend error boundaries and React Query global error handling to surface clear user feedback.
  • Axios interceptors to log and manage server errors consistently.
  • Optimistic UI updates with rollback on mutation failures.

Quick Start

Configure the custom exception handler in Django settings and wire frontend error handling strategies to surface consistent error feedback.

Frequently Asked Questions about error-handling

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I handle Django IntegrityError and ProgrammingError in DRF responses?▼

Handle Django IntegrityError and ProgrammingError by configuring a centralized DRF exception handler that maps database and permission errors into structured, client-friendly API responses.

What is the best way to prevent race conditions with Django select_for_update?▼

Prevent race conditions using Django select_for_update for pessimistic locking, or apply optimistic updates with filter().update() to safely manage concurrent database modifications.

How do I implement React error boundaries with React Query for global error handling?▼

Implement React error boundaries and React Query global error handling to orchestrate frontend errors, surfacing clear user feedback when server or runtime errors occur.

Does this error handling approach support optimistic UI updates with rollback?▼

Yes, this approach supports optimistic UI updates with automatic rollback on mutation failures, ensuring React interfaces recover gracefully when Axios interceptors detect server errors.

When do I need savepoint handling for materialized views in Django transactions?▼

Use savepoint handling for materialized views in Django transactions to guard database operations against failures caused by missing or concurrently refreshing views.
