odoo-report（奥多报告）

Odoo Email Templates & QWeb Reports Skill (v2.1)

A skill for creating, managing, debugging, and migrating Odoo email templates and QWeb reports across versions 14-19.

Workflows

This skill handles all template and report workflows via natural language:

Configuration

• Supported Versions: Odoo 14, 15, 16, 17, 18, 19
• Core Model: mail.template
• Rendering Engines: inline_template (Jinja2-like) for headers, QWeb for body_html

User overrides: Check for odoo-report.local.md in the project .claude/ directory. If found, use its YAML frontmatter settings (default_version, author, default_layout) as defaults.

Template Architecture

mail.template
├── Inherits: mail.render.mixin (rendering engine)
├── Inherits: template.reset.mixin (reset - Odoo 16+)
│
├── Header Fields (inline_template engine):
│   subject, email_from, email_to, email_cc, reply_to, partner_to
│
├── Content Fields (QWeb engine):
│   body_html
│
├── Attachment Fields:
│   attachment_ids (static)
│   report_template (Odoo 14-16) / report_template_ids (Odoo 17+)
│   report_name (dynamic filename)
│
└── Configuration:
    email_layout_xmlid, auto_delete, mail_server_id,
    use_default_to, scheduled_date, template_category (16+)

Rendering Flow

mail.template.send_mail_batch(res_ids)
  ├─► _generate_template(res_ids, render_fields)
  │     ├─► _classify_per_lang()
  │     ├─► _render_field() per field (inline_template or qweb)
  │     ├─► _generate_template_recipients()
  │     ├─► _generate_template_attachments() (static + PDF report)
  │     └─► Return rendered values dict
  ├─► Create mail.mail records
  ├─► Apply email_layout_xmlid (if set)
  └─► Send via mail_server_id or default

Two Rendering Engines

1. Inline Template (Jinja2-like)

Used for: subject, email_from, email_to, email_cc, reply_to, partner_to, lang, scheduled_date

{{ object.name }}
{{ object.partner_id.name }}
{{ (object.user_id.email_formatted or user.email_formatted) }}
{{ object.state == 'draft' and 'Quotation' or 'Order' }}
{{ ctx.get('proforma') and 'Proforma' or '' }}

2. QWeb Engine

Used for: body_html

<!-- Output (use t-out for Odoo 15+, t-esc for Odoo 14) -->
<t t-out="object.name"/>
<t t-out="format_amount(object.amount_total, object.currency_id)"/>

<!-- Conditionals -->
<t t-if="object.state == 'draft'">Draft</t>
<t t-elif="object.state == 'sent'">Sent</t>
<t t-else="">Confirmed</t>

<!-- Loops -->
<t t-foreach="object.order_line" t-as="line">
    <tr><td t-out="line.name"/></tr>
</t>

<!-- Dynamic attributes -->
<a t-att-href="object.get_portal_url()">View</a>

Version Decision Matrix

Version Detection Priority

1. User-specified --version flag
2. Directory path (odoo14, odoo17, etc.)
3. __manifest__.py version string (e.g., '17.0.1.0.0')
4. Ask user if ambiguous

Email Layout Templates

Best Practices

1. Always Use Fallbacks

<t t-out="object.partner_id.name or 'Valued Customer'"/>

2. Use Format Helpers

<t t-out="format_amount(object.amount_total, object.currency_id)"/>
<t t-out="format_date(object.date_order)"/>

3. Use Layouts for Consistency

<field name="email_layout_xmlid">mail.mail_notification_layout</field>

4. Handle Empty HTML (16+)

<t t-if="not is_html_empty(object.description)">
    <div t-out="object.description"/>
</t>

5. Version-Appropriate Output

<!-- Odoo 15+ --> <t t-out="value"/>
<!-- Odoo 14 -->  <t t-esc="value"/>

6. Report Attachment by Version

<!-- Odoo 14-16 -->
<field name="report_template" ref="module.report_action"/>
<!-- Odoo 17+ -->
<field name="report_template_ids" eval="[(4, ref('module.report_action'))]"/>

7. Email Tables for Compatibility

<!-- Email clients require table-based layout with inline styles -->
<table border="0" cellpadding="0" cellspacing="0" width="100%">
    <tr><td style="padding: 20px;">Content</td></tr>
</table>

8. Safe Dynamic Filenames

<field name="report_name">{{ (object.name or 'Document').replace('/', '-') }}</field>

wkhtmltopdf (Required for PDF Reports)

Installation

# Windows
winget install wkhtmltopdf.wkhtmltox

# Ubuntu/Debian
sudo apt-get install wkhtmltopdf

# macOS
brew install wkhtmltopdf

Odoo Configuration (MANDATORY)

[options]
bin_path = C:\Program Files\wkhtmltopdf\bin   # Windows
# bin_path = /usr/local/bin                    # Linux

Key Limitation: OFFLINE Mode

wkhtmltopdf runs WITHOUT network access:

• Google Fonts CDN will NOT load
• External images will NOT render
• Use web.external_layout for fonts
• Use system fonts: 'DejaVu Sans', 'Arial', sans-serif

Common Errors

Arabic/RTL Support

MANDATORY Template Wrapper for Non-Latin Text

<template id="report_document">
    <t t-call="web.html_container">        <!-- Provides UTF-8 meta tag -->
        <t t-foreach="docs" t-as="o">
            <t t-call="web.external_layout"> <!-- Loads proper fonts -->
                <div class="page">
                    <!-- Content here -->
                </div>
            </t>
        </t>
    </t>
</template>

Without web.html_container, Arabic text displays as Ùاتورة (UTF-8 bytes read as Latin-1).

Bilingual Labels

<th style="background: #1a5276; color: white; padding: 12px;">
    Date | التاريخ
</th>

RTL Alignment

<div style="direction: rtl; text-align: right;">
    يرجى إرسال حوالاتكم على الحساب المذكور أعلاه
</div>

Report SCSS Styling

Asset Bundle

'assets': {
    'web.report_assets_common': [
        'module/static/src/scss/report_styles.scss',
    ],
},

Google Fonts Pitfall

// BROKEN - Semicolons in URL break SCSS parsing
@import url('https://fonts.googleapis.com/css2?family=Poppins:wght@300;400;500;600;700&display=swap');

// FIXED - Use weight range syntax
@import url('https://fonts.googleapis.com/css2?family=Poppins:wght@300..700&display=swap');

// BEST - Don't use Google Fonts (wkhtmltopdf is offline!)

Recommended Font Stack

$report-font-family: 'DejaVu Sans', 'Arial', 'Helvetica', sans-serif;

Paper Format Configuration

<record id="paperformat_custom" model="report.paperformat">
    <field name="name">Custom A4</field>
    <field name="format">A4</field>
    <field name="orientation">Portrait</field>
    <field name="margin_top">20</field>
    <field name="margin_bottom">20</field>
    <field name="margin_left">15</field>
    <field name="margin_right">15</field>
    <field name="header_line" eval="False"/>
    <field name="dpi">90</field>
</record>

Link to report: <field name="paperformat_id" ref="module.paperformat_custom"/>

Debug Workflow

When diagnosing report or template issues, follow this order:

1. Infrastructure: wkhtmltopdf installed? bin_path in odoo.conf? Server restarted?
2. Template structure: web.html_container → web.external_layout → div.page?
3. Report action: report_name matches template id? binding_model_id correct?
4. Shell test: env.ref('module.report_action')._render_qweb_pdf([record_id])
5. Browser cache: Clear cache (Ctrl+Shift+R)

Migration Workflow

1. Detect source version (syntax heuristics or directory name)
2. Create backup: {file}.bak
