Django Transactions & Concurrency

Handle race conditions, locking, and transaction boundaries in Django.

Overview

Django provides robust transaction management to ensure data consistency:

• atomic - Transaction boundaries with rollback on error
• select_for_update - Row-level locking for concurrent access
• on_commit - Deferred callbacks after transaction commits
• update_or_create - Upserts with race condition handling
• M2M ordering - ManyToMany relationships require PK first
