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 |

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')
