"Executing DDL statements while in a transaction on databases "
TransactionManagementError: Executing DDL statements while in a transaction on databases that can't perform a rollback is prohibited.
This occurs when we attempt to drop a db table's constraints and indexes before loading. Apparently MySQL doesn't support transactional DDL statements, though PostgreSQL, SQL Server and a few other db managers do.
There might be a way around this. Like instead of using the Django schema_editor, we could build the SQL statement and execute it raw. Feels a little dangerous, though.
For now, I'll skip the dropping and re-adding of constraints and indexes when loading into MySQL.
Got this error when testing Django 1.11:
