DTG Base Skill Complete reference for DTG Base module utilities and helpers in Odoo 18. What is DTG Base? DTG Base is a custom abstract model ( dtg_base.DTGBase ) that provides common utility methods for Odoo development. It's designed to be inherited by other models to gain access to helpful utilities. Quick Reference Utility Description Date & Period Find first/last date of period, period iteration Timezone Convert local to UTC, UTC to local Barcode Check barcode exists, generate EAN13 Batch Processing Split large recordsets into batches after_commit Execute code after transaction commit Vietnamese Text Strip accents, convert to non-accent File Utilities Zip directories, get file size Number Utilities Round to decimal places Main Guide File : odoo-18-dtg-base-guide.md When to use this skill Working with DTG Odoo codebase Need date/period calculations Timezone conversions Barcode validation Batch processing large recordsets Vietnamese text processing File zipping utilities DTGBase Abstract Model Inherit from DTGBase Location : addons_customs/erp/dtg_base/models/dtg_base.py from odoo import models class MyModel ( models .
