SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill prevents common, production-breaking mistakes when implementing Frappe Jinja templates for Print Formats, Email/Notification templates, Portal pages, and reusable template methods.

Core Features & Use Cases

  • Choose the correct template type & engine behavior: uses Jinja syntax for Print Formats and templates, and warns about JS microtemplates for Report Print Formats to avoid blank output.
  • Implement correct formatting and localization: ensures numbers, dates, and currency use doc.get_formatted() and wraps user-facing strings with _() for translations.
  • Render safely and efficiently: avoids N+1 queries in templates, handles null values with defaults/conditionals, and restricts | safe usage to trusted HTML only.
  • Support full template workflows: covers Print Format creation, Email Template/Notification message authoring, Portal page context + rendering, custom jenv methods/filters, and practical debugging patterns.
  • Handle PDF rendering differences across Frappe versions: includes rules and CSS guidance to reduce wkhtmltopdf inconsistencies and notes V16 Chrome PDF differences.

Quick Start

Ask the AI to generate a complete Jinja Print Format template for Sales Invoice (v14/v15) that renders correctly in PDF by using get_formatted for currency/date, safe child-table formatting with row.get_formatted(..., doc), and translation-ready labels.

FAQPage Schema
How do I create a Frappe Jinja Print Format that renders correctly in PDF?▼

To create a Frappe Jinja Print Format that renders correctly in PDF, use Jinja syntax with proper Frappe variables like doc and frappe._. Apply doc.get_formatted() for currency and dates, use row.get_formatted(..., doc) for child tables, and wrap user-facing strings with _() for translations.

Why does my Frappe Print Format show blank output when printing a report?▼

Frappe Report Print Formats show blank output when using Jinja syntax instead of JS microtemplates.
