I'm running into this issue:

sqlite3.IntegrityError: UNIQUE constraint failed: ordering_orderround.collect_datetime

I'm assuming this is because there are existing OrderRounds with not equal dates.

When I removed the Order round with equal dates the migrate went successfully.

I'm assuming this fails because unit tests create OrderRounds on the same date (now)?

Yeah it looks like the collect_datetime is autofilled and it's not unique.

I'm closing this one, it's probably not the right approach.
