Type: Uncategorized | Status: new
Component: Database layer | Version: 1.8alpha1
(models, ORM) | Keywords: DateTimeRangeField
Severity: Normal | decompress

-------------------------------------+-------------------------------------
1. Create a model with a DateTimeRangeField and another field (I used just
one other, a SlugField)
2. Via the admin, add a record with a valid slug and datetimerange
3. Try to edit the record, changing the slug
(This was done with a Postgres backend)
