When Odoo Overrides Collide: Why “Deterministic” Does Not Mean “Safe”

📰 Medium · Python

Learn how Odoo's modular architecture can lead to overriding collisions and why deterministic doesn't mean safe, with practical steps to manage these issues

intermediate Published 11 May 2026
Action Steps
  1. Install Odoo and create a new module to understand the modular architecture
  2. Extend an existing model by writing a class with the same _name to see how overrides work
  3. Configure multiple addons to override the same model and observe potential collisions
  4. Test the behavior of deterministic overrides and analyze the results
  5. Apply best practices to avoid overriding collisions and ensure safe module implementation
Who Needs to Know This

Developers and engineers working with Odoo and Python will benefit from understanding how to manage overriding collisions and ensure safe implementation of modules

Key Insight

💡 Deterministic overrides in Odoo do not guarantee safety, and developers must take steps to manage potential collisions
