Apply Odoo 18.0 coding standards for clean, upgrade-friendly code (bridge to 19).
<list> (19 mandates); direct attributes (readonly="state == 'done'") over attrs; <chatter/> available.models.Constraint; _sql_constraints still valid; @api.constrains for logic.@api.model_create_multi for create.type='json' still works; adopt type='jsonrpc' for forward compatibility.self._context works; can use self.env.context..mapped().NewIdA compute (e.g. a related-record count feeding a form smart button) that
builds a dict via read_group()/search_count() keyed by self.id, then
does a raw dict lookup like counts[record.id], throws
KeyError: <NewId 0x... instance> the moment a user opens a brand-new,
unsaved form — the in-memory NewId record is never a key in that dict
because it has no matching related rows yet. Always use counts.get(record.id, 0)
(or equivalent .get() with a safe default) in any compute that indexes a
read_group/aggregate result by record id. This is a real, reproducible bug
class — verified live in production Odoo 18 code, not theoretical (see
docs/docker-sandbox/phase-8/live-test.md step 7 in odoo-agent-pro-kit).
CRITICAL: All XML data files (views, data, security, reports, menus) MUST follow the RELAX NG schema defined in odoo/import_xml.rng. This schema is the authoritative definition of valid XML structure.
Root elements: <odoo>, <openerp>, or <data> (with optional noupdate, auto_sequence, uid, context attributes)
Record structure:
<record id="unique_id" model="model.name">
<field name="field_name">value</field>
<!-- Field types: base64, char, file, int, float, list, tuple, html, xml -->
<!-- Field attributes: ref, eval, search (mutually exclusive) -->
</record>
Template structure:
<template id="unique_id" name="Template Name" inherit_id="base.template" primary="True">
<!-- Optional: t-name, forcecreate, context, priority, groups, active -->
</template>
Menu items:
<!-- Root menu: can have web_icon, action, children -->
<menuitem id="menu_root" name="Root" web_icon="module,static/icon.png" sequence="10"/>
<!-- Sub-menu: requires parent, can have action OR children -->
<menuitem id="menu_sub" name="Sub" parent="menu_root" action="action_id" groups="base.group_user"/>
Window actions:
<act_window id="action_id" name="Action" res_model="model.name" view_mode="tree,form"
domain="[]" context="{}" target="current" groups="base.group_user"
binding_model="other.model" binding_type="action"/>
❌ WRONG:
<record model="ir.ui.view"> <!-- Missing required 'id' -->
<field name="x" type="int" eval="123"/> <!-- Can't mix type with eval -->
<field name="x" ref="module.id" eval="123"/> <!-- Can't mix ref with eval -->
<menuitem id="x" web_icon="icon.png" parent="y"/> <!-- web_icon only for root menus -->
<module> <!-- Invalid root element -->
✅ CORRECT:
<odoo>
<record id="view_form" model="ir.ui.view">
<field name="name">model.form</field>
<field name="arch" type="xml">
<form><field name="name"/></form>
</field>
</record>
</odoo>
