Odoo 17.0 Development Skill

A comprehensive skill set for building production-quality Odoo 17.0 custom modules. Covers the full development lifecycle: module structure, ORM, views, actions, performance, and testing — following official Odoo coding guidelines.

When to Apply

Reference these rules when:

• Creating or extending a custom Odoo 17.0 module
• Defining models, fields, or compute methods
• Writing @api decorators, constraints, or onchange handlers
• Building XML views, menus, and actions
• Optimizing queries or processing large recordsets
• Writing unit tests, integration tests, or UI tours
• Adding chatter, sequences, ratings, or portal access to a model

3	ORM Fields	HIGH	fields-
4	API Decorators	HIGH	decorators-
5	Recordset & Domains	MEDIUM	recordsets-
6	Actions	MEDIUM	actions-
7	Performance	MEDIUM	performance-
8	Testing	MEDIUM	testing-
9	Mixins	LOW	mixins-

Quick Reference

1. Module Manifest (HIGH)

• manifest-required-keys — Every module must have name, version, depends, license, installable
• manifest-data-order — Security CSV always first in data, menus always last
• manifest-assets-bundle — Register JS/OWL/SCSS files under assets.web.assets_backend
• manifest-version-format — Use {odoo}.{major}.{minor}.{patch} e.g. 17.0.1.0.0
• manifest-dependencies — Missing or wrong depends prevents module installation

2. ORM Models (HIGH)

• models-class-order — Follow canonical attribute → field → constraint → compute → CRUD → action → helper order
• models-type-selection — Use Model for persistence, TransientModel for wizards, AbstractModel for mixins
• models-inherit-modes — Know the 4 _inherit modes: extend, copy, compose, delegate
• models-sql-constraints — Prefer _sql_constraints over Python for uniqueness checks
• models-required-attributes — _name and _description are required on every new model

3. ORM Fields (HIGH)

• fields-monetary-currency — Monetary fields always require a paired currency_field
• fields-many2one-index — Always set index=True on Many2one fields used in searches
• fields-store-decision — Use store=True only when field needs to be searched or sorted
• fields-m2m-commands — Use ORM write commands (0,0,v) (4,id) (6,0,ids) for relational writes
• fields-selection-add — When extending a Selection, always define ondelete for new keys

4. API Decorators (HIGH)

• decorators-depends-completeness — List ALL fields that affect the computed result
• decorators-depends-assign-all-branches — Always assign computed field in every code path
• decorators-constrains-exception — @api.constrains must raise ValidationError, never UserError
• decorators-constrains-loop — Always loop for rec in self inside @api.constrains
• decorators-onchange-not-enforced — @api.onchange does not run on programmatic create/write
• decorators-onchange-newid — self.id inside @api.onchange is a NewId, not an integer
• decorators-create-multi — Always use @api.model_create_multi for create() overrides in 17.0
• decorators-depends-context-no-store — Fields with @api.depends_context cannot be store=True

5. Recordset & Domains (MEDIUM)

• recordsets-search-count — Use search_count() instead of len(search()) for counting
• recordsets-batch-write — Call write() on the whole recordset, never inside a loop
• recordsets-batch-create — Pass a list to create([...]) instead of calling it in a loop
• recordsets-domain-operators — | and & are prefix operators applying to the next two conditions
• recordsets-sudo-comment — Always add a comment explaining why sudo() is used
• recordsets-raw-sql-params — Never format SQL strings; always use %s parameterized queries

6. Actions (MEDIUM)

• actions-window-menu — Always bind leaf <menuitem> to an ir.actions.act_window record
• actions-data-order — Declare actions in view XML, menus in a separate menus.xml loaded last
• actions-python-return — Return action dicts from Python methods to open views or wizards
• actions-cron-method — Cron methods must be decorated with @api.model and handle their own errors
• actions-server-binding — Use binding_model_id to add server actions to the Action dropdown

7. Performance (MEDIUM)

• performance-prefetch — Rely on ORM prefetch; use mapped() to extract cross-record field values
• performance-no-loop-write — Never call write() or create() inside a for loop
• performance-index-searched-fields — Add index=True on fields used in search() domains or ORDER BY
• performance-read-group — Use read_group() for aggregations instead of loading full recordsets
• performance-invalidate-after-sql — Call invalidate_model() after any raw SQL write

8. Testing (MEDIUM)

• testing-setup-class — Use setUpClass for shared fixtures; setUp only when full isolation is needed
• testing-post-install-tag — Tag tests with @tagged('post_install', '-at_install')
• testing-constrains-coverage — Every @api.constrains method must have a test that triggers it
• testing-wizard-pattern — Test wizards by creating them with context, then calling the action method
• testing-tour-js — UI tours must be registered in the web_tour.tours registry and tested via HttpCase

9. Mixins (LOW)

• mixins-mail-thread — Add _inherit = ['mail.thread', 'mail.activity.mixin'] for chatter + activities
• mixins-tracking — Use tracking=True on fields to log changes in the chatter automatically
• mixins-sequence — Use ir.sequence + next_by_code() in field default= for auto-numbering
• mixins-portal — Implement _compute_access_url when using portal.mixin
• mixins-message-post — Use message_post() for programmatic chatter messages
