Odoo Code Reviewer

Python Guidelines

General

• PEP8: Strictly follow PEP8 (120 chars line length is often acceptable in Odoo).
• Imports:
  • odoo imports first.
  • from odoo import models, fields, api, _
  • from odoo.exceptions import UserError, ValidationError

ORM Methods

• Search: Use search_count() instead of len(search()).
• Filtered: Use filtered() for in-memory filtering of recordsets.
• Mapped: Use mapped() to extract values.
• Write/Create: Batch operations where possible.
• SQL: Avoid direct SQL (self.env.cr.execute) unless absolutely necessary for performance. If used, never inject variables directly; use parameters.

Fields & Models

• Naming:
  • Fields: snake_case. Many2one fields usually end with _id (e.g., partner_id).
  • One2many/Many2many: usually plural (e.g., line_ids, tag_ids).
• Computed Fields: Always add @api.depends.
• Constrains: Use @api.constrains for data integrity checks.
• Translations: Wrap user-facing strings in _().

XML Guidelines

Views

• Records: Use <record id="..." model="ir.ui.view">.
• Arch: All views must have an <arch type="xml"> block.
• XPath: Use concise XPath expressions. Prefer name attributes over indices.
  • Bad: //field[3]
  • Good: //field[@name='description']
• Attributes:
  • invisible: Use strictly for hiding.
  • readonly: For uneditable fields.
  • required: For mandatory fields.
• Noids: Avoid hardcoded database IDs. Use ref="module.xml_id".

Data Files

• NoUpdate: Use noupdate="1" in <data> for data that shouldn't be reset on upgrade (like sequence numbers or cron jobs).

Manifest (manifest.py)

• Ensure depends lists all required modules.
• Ensure data lists all XML/CSV files in correct order (security -> views -> data).
• Ensure license is specified (e.g., LGPL-3).

Review Checklist

1. Security: Are access rights (ir.model.access.csv) defined?
2. Performance: Are there loops doing SQL queries inside? (N+1 problem).
3. Upgrade: Will this code break on module update?
4. Idempotency: Can this XML be loaded multiple times without duplicating data?
