The core script ``l10n_fr_account/migrations/2.1/end-migrate_update_taxes.py``
calls ``account.chart.template.try_loading('fr', company)``. During
``_post_load_data``, Odoo 18 resolves the French template's default accounts via
``self.ref()`` WITHOUT ``raise_if_not_found=False`` (chart_template.py:711/714
and the ``_get_property_accounts`` loop at :746). If any expected
``account.<company>_<key>`` xml-id is missing, it raises
``ValueError: External ID not found`` and aborts the registry load.
This happens when a database customized its chart of accounts: the generic PCG
account was deleted (e.g. 607000) or recreated without its xml-id (e.g. 707000).
Add a generic ORM ``post-migration`` script that, for every company with a
``chart_template``, reads the expected account xml-ids from the template API
(``_get_property_accounts`` / ``_get_chart_template_data`` /
``_get_account_account``) and recreates any missing ``account.<company>_<key>``
``ir.model.data`` pointing to the best matching account: exact code, else the
company account sharing the longest common code prefix, else a non-blocking
warning. It runs at stage ``post`` (before the native ``end`` script) and only
creates missing xml-ids — no account is modified. Idempotent, generic across
all migrated FR databases.
Remove the previous hardcoded 607/707 SQL block from
``versions/18.0/pre_upgrade.sh`` now superseded by this script.
Custom migration scripts for a core module used to require copying the
whole module into ``versions/18.0/addons/`` so its ``migrations/`` folder
would be picked up. Because the migration container mounts that copy with
priority (``--addons-path=mig,addons``) and ``get_module_path`` returns the
first match, the copy fully shadowed the core module — dragging along its
entire data/models just to carry one script.
Instead, inject the scripts through a dedicated OpenUpgrade ``upgrade_path``:
- New ``versions/18.0/scripts/l10n_fr_account/18.0.2.2/`` holding
``pre-migration-0k-fix-orphan-expressions.py`` (converted to the
``@openupgrade.migrate()`` / ``migrate(env, version)`` convention) and
``post-migration-0k-vat-box25.py`` + ``noupdate_changes.xml`` that reapply
the box 25 VAT-report customization via ``openupgrade.load_data``.
- ``config/compose.yml``: mount it as ``/opt/odoo/auto/upgrade`` for ou18.
- ``versions/18.0/upgrade.sh``: pass
``--upgrade-path=/opt/odoo/auto/upgrade,/opt/odoo/auto/addons/openupgrade_scripts/scripts``.
Odoo appends every path to ``odoo.upgrade.__path__`` and concatenates the
per-version scripts, so our scripts run IN ADDITION to the native ones;
the native path is listed explicitly because ``--upgrade-path`` overrides
``config['upgrade_path']`` which ``openupgrade_framework`` only sets when empty.
Files are named with a ``-0k-`` marker so they never collide with the native
``pre-migration.py`` / ``post-migration.py``. This removes the need for the
shadowing module copy entirely.
Also ignore ``__pycache__``/``*.pyc``.
