I continued to work on on data import (cpas2lino) for #147.

When running cpas2lino a second time on the same database, it can take a considerable time to delete the vouchers generated by the previous run. Here is how I can save that time.

I create a delete_ledger.sql with this content (a manual selection from the output of sqlflush):

BEGIN;
DELETE FROM "ledger_voucher";
DELETE FROM "vatless_accountinvoice";
DELETE FROM "finan_bankstatement";
DELETE FROM "finan_journalentryitem";
DELETE FROM "finan_bankstatementitem";
DELETE FROM "ledger_movement";
DELETE FROM "vatless_invoiceitem";
DELETE FROM "finan_paymentorder";
DELETE FROM "finan_journalentry";
DELETE FROM "finan_paymentorderitem";
COMMIT;

Note that the output of sqlflush depends on the database engine. For MySQL it is different than for SQLite.

And then I run the following command before doing cpas2lino:

$ cat delete_ledger.sql | python manage.py dbshell
