Sequence Mixin Extension

Add daily reset support to Odoo 19 accounting sequence detection without patching core files.

This module extends Odoo's native sequence logic so account.move can recognize and work with daily reset numbering such as BILL/2026/05/02/0001. It is designed as a narrow, upgrade-friendly extension: native yearly, monthly, and financial-year behaviors stay intact, while a new day reset mode becomes available when the sequence format explicitly includes a day component.

Highlights

• Detects daily reset sequence patterns like PREFIX/YYYY/MM/DD/0001.
• Preserves standard Odoo sequence behaviors for:
  • yearly reset
  • monthly reset
  • year-range reset
  • year-range-month reset
  • fixed numbering
• Extends account.move warnings so daily formats are explained correctly to users.
• Extends the Resequence Wizard preview and recomputation flow for daily periods.
• Respects sequence_override_regex on journals.
• Keeps all changes addon-local with no Odoo core edits.

Example

Once a journal is intentionally using a daily sequence pattern, Odoo can continue with values such as:

INV/2026/05/02/0001
INV/2026/05/02/0002
INV/2026/05/03/0001

Technical Notes

• models/sequence_mixin.py Introduces the custom daily regex, reset deduction, date-range handling, and next-sequence formatting support.
• models/account_move.py Extends the onchange warning logic so daily sequence structures are recognized and described correctly.
• models/account_resequence.py Enhances preview and recomputation logic in account.resequence.wizard for exact per-day periods.
