# 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](#date--period-utilities) | Find first/last date of period, period iteration |
| [Timezone](#timezone-conversion) | Convert local to UTC, UTC to local |
| [Barcode](#barcode-utilities) | Check barcode exists, generate EAN13 |
| [Batch Processing](#batch-processing) | Split large recordsets into batches |
| [after_commit](#after_commit-decorator) | Execute code after transaction commit |
| [Vietnamese Text](#string--text-utilities) | Strip accents, convert to non-accent |
| [File Utilities](#file-utilities) | Zip directories, get file size |
| [Number Utilities](#number-utilities) | Round to decimal places |

## DTGBase Abstract Model

### Inherit from DTGBase

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

```python
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')
```
