Release 1.7.1 of pretix

If you already upgraded to today's release 1.7.0, you might have run into the following error on MySQL:

django.db.utils.OperationalError: (1072, "Key column 'payment_fee_tax_rule_id' doesn't exist in table")

Or on PostgreSQL:

psycopg2.ProgrammingError: column "payment_fee_tax_rule_id" does not exist

On PostgreSQL

On PostgreSQL, you can just upgrade to version 1.7.1 directly and run migrations like you normally would.

On MysQL

On MySQL, if you created a backup before the upgrade, please revert to it and upgrade to 1.7.1 directly. If you do not have a current backup, please proceed with the following steps:

First, create a full backup of your database. Then, upgrade to pretix 1.7.1 without running migrations.

Now execute the following command:

python3 -m pretix migrate --fake pretixbase 0077_auto_20170829_1126

And the following SQL commands on your database:

ALTER TABLE `pretixbase_taxrule`
    ADD CONSTRAINT `pretixbase_taxrule_event_id_178a74ee_fk_pretixbase_event_id`
    FOREIGN KEY (`event_id`) REFERENCES `pretixbase_event` (`id`);
ALTER TABLE `pretixbase_item`
    ADD CONSTRAINT `pretixbase_item_tax_rule_id_f501b784_fk_pretixbase_taxrule_id`

    ADD CONSTRAINT `pretixbase_subeventm_subevent_id_b97a87d2_fk_pretixbas`

    ADD CONSTRAINT `pretixbase_orderfee_tax_rule_id_082755a4_fk_pretixbas`
    FOREIGN KEY (`tax_rule_id`) REFERENCES `pretixbase_taxrule` (`id`);

You can then complete upgrade to 1.7.1.
