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.
| 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 |
