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

DTGBase Abstract Model

Inherit from DTGBase

Location: addons_customs/erp/dtg_base/models/dtg_base.py

from odoo import models

class MyModel(models.Model):
    _name = 'my.model'
    _inherit = ['dtg_base.dtg_base']

    def my_method(self):
        # Now you have access to all DTGBase utilities
        first_date = self.find_first_date_of_period('2024-01-15', 'month')
        utc_date = self.convert_local_to_utc('2024-01-15 10:00:00')
