AccountingService: maps Transaction dataclasses to journal entries and posts to the Ledger.
Supports reversal (counter-entries) for step-back simulation.
Classes:
-
AccountingService–Maps Transaction records to journal entries and posts them to a Ledger.
AccountingService()
Maps Transaction records to journal entries and posts them to a Ledger.
The service looks up named accounts from the ledger's chart of accounts so that callers do not need to pass account references explicitly.
Methods:
-
post–Map transaction to journal entries and post each one to ledger.
-
post_all–Post all transactions to ledger and update positions as needed.
-
reverse–Post the reversal (counter-entries) of transaction to ledger.
post(transaction: Transaction, ledger: Ledger) -> None
Map transaction to journal entries and post each one to ledger.
post_all(
transactions: list[Transaction],
ledger: Ledger,
position_store: PositionStore,
) -> None
Post all transactions to ledger and update positions as needed.
reverse(transaction: Transaction, ledger: Ledger) -> None
Post the reversal (counter-entries) of transaction to ledger.
This undoes the effect of a prior :meth:post call for the same
transaction, restoring account balances to their pre-post state.
