Added support for serialization ofuuid.UUIDobjects. Models¶ Added support for callable values in thedefaultsargument ofQuerySet.update_or_create()andget_or_create(). ImageFieldnow has a defaultvalidate_image_file_extensionvalidator. (This validator moved to the form field inDjango 1.11.2.) ...
With Django, I want to build a queryset with related objects from a ManyToManyField relation. My goal is to aggregate related values in a list, as a group by or string_agg in SQL. Here is my setup: models.py class BaseModel(models.Model): id = models.UUIDField( primary_key = True...
Thank you for the quick answer. However, the proposed solution does not work as changing the uuid lookup to exact causes an error when searching for any string other than valid uuid value. I get ValidationError raised from UUIDField.to_python() ...
On MariaDB 10.7+,UUIDFieldis now created asUUIDcolumn rather thanCHAR(32)column. As a consequence, anyUUIDFieldcreated in Django < 5.0 should be replaced with aUUIDFieldsubclass backed byCHAR(32): classChar32UUIDField(models.UUIDField):defdb_type(self,connection):return"char(32)"defget_db...
Replying toIan Foote: I don't think this field has to be very generic because DBs pk types are very limited. As far as I know, only ints and UUIDs make sense for pk. While I'm not sure it would make sense in anAutoField, string primary keys are possible. For example, you could...
