If datetimefield is not timezone-aware get_or_create fails.

[mmkhitaryan]

SELECT "sold_date","id","review","created_at","seller_id","buyer_id","purshare_type_id" FROM "purchase" WHERE "id"=94562 AND "sold_date"='2024-02-10 13:55:04' AND "review"='' AND "purshare_type_id"=1 AND "buyer_id"=2 AND "seller_id"=1 LIMIT 2

This sql query got generated before I made the sold_date timezone.make_aware()

SELECT "seller_id","purshare_type_id","sold_date","created_at","buyer_id","id","review" FROM "purchase" WHERE "id"=93707 AND "sold_date"='2024-01-29 04:16:46+00:00' AND "review"='' AND "purshare_type_id"=2 AND "buyer_id"=20 AND "seller_id"=1 LIMIT 2: None

Before I made the datetime timezone-aware, get_or_none would fail with UNIQUE CONSTRAINT error.

I want to understand, is it a bug or a feature? Because to me it sounds like a bug. IMHO tortoise should at least show warning message that the datetime field must be timezone-aware.

Making the sold_date datetime field timezone-aware fixed the problem for me: mmkhitaryan/odinscraper@cfd1f70#diff-e544f072d0253f9a2c630fb985108e2f779a5d5db5e7eb0cb6319304756ceee3R107

I have implemented minimal reproducible example: https://gist.github.com/mmkhitaryan/bf46cb557cae421452ba938989005b70
When you run it, you get "successfully created" message but when the datetime is naive you get error below:
