Ticket #58 (closed defect: fixed)
Attribute errors cause MySQL to partially apply a migration
|Reported by:||andrew@…||Owned by:||andrew|
add_column(...) add_index(...) <---- oops!
will obviously not work, but mysql won't rollback the added column.
- For mySQL, do a dry run and warn if things might break
- If there's an exception during migration, output the sql from reverse() to try and assist
- Suggest the user changes to postgres ;)
