"""Data-adapter base class: routes data lookups across three backends.
|
|
|
|
The fusion_accounting_ai sub-module's tools (e.g. get_unreconciled_bank_lines)
|
|
must work in any of three install profiles:
|
|
|
|
1. FUSION mode — a fusion native sub-module (e.g. fusion_accounting_bank_rec)
|
|
is installed; route to its model.
|
|
2. ENTERPRISE mode — Odoo Enterprise (e.g. account_accountant) is installed;
|
|
route to Enterprise APIs.
|
|
3. COMMUNITY mode — neither; fall back to a pure Odoo Community search/read.
|
|
|
|
Subclasses implement the three backend methods and define which fusion model
|
|
and which Enterprise module they probe.
