您可以使用ModelManager和覆盖默认值objects，例如：
class ExcludeNotAccepted(models.Manager):
def get_queryset(self):
return super().get_queryset().exclude(accepted=False)
class SomeClassModel(models.Model):
value = models.CharField(max_length=244)
accepted = models.BooleanField(default=False)
# make the default objects exclusive of non-accepted
objects = ExcludeNotAccepted()
# still allow explicit access via another name
all_objects = models.Manager()
在访问SomeClassModel.objects.all()时自动过滤掉不可接受的项目具有预期的效果，但是您仍然可以通过显式使用SomeClassModel.all_objects.all()... 访问所有对象。

Mamba is a new state space model architecture showing promising performance on information-dense data such as language modeling, where previous subquadratic models fall short of Transformers. It is based on the line of progress on structured state space models, with an efficient hardware-aware design and implementation in the spirit of FlashAttention.
