Base Addon Deep Dive

The base addon provides the foundation for all Odoo applications.

Key Models

• ir.model, ir.model.fields: model metadata and fields registry.
• ir.ui.menu, ir.actions.*: client actions and menu hierarchy.
• ir.config_parameter: runtime configuration key/value store.
• ir.attachment: binary attachments with filestore storage.
• res.users, res.groups, res.company, res.partner, res.currency.

Controllers

• Minimal endpoints for attachments and common actions.

Security

• Group definitions and default access rights via ir.model.access.csv.
• Record rules for multi-company and user-specific data.

Data

• Seed actions, menus, parameters, currencies, companies, languages.

Notes

• Many application modules only extend these models via _inherit.
