Coding Conventions

Before writing code, run the odoo-workflow skill if it is installed (trace the real source, Context Brief with file:line, definition of done); install it alongside this pack.

Read references/api-highlights.md before writing code and apply its Quick review checks: the ❌ items are what not to use in Odoo 19.

Apply the convention section in the guide you open. Odoo 19 runtime behavior, then existing stable-addon style, takes precedence; keep diffs focused.

  • Module naming, assets, JavaScript, CSS, and SCSS: development guide.
  • XML formatting and IDs: data, actions, reports, security, and views guides.
  • Python, recordsets, transactions, and translations: model, field, decorator, performance, transaction, and translation guides.
