This is with Django v2.2.
We use tombstoning via a custom BaseModelManager to mark items as deleted
in the database but keep them around for reference.
class BaseModelManager(models.Manager):
def __init__(self, *args, **kwargs):
self.include_tombstoned = kwargs.pop('include_tombstoned',False)
super(BaseModelManager, self).__init__(*args, **kwargs)
def get_queryset(self):
if not self.include_tombstoned:
return
TombstonedQuerySet(self.model).filter(is_tombstoned=False)
return TombstonedQuerySet(self.model)
class BaseModel(models.Model):
def __init__(self, *args, **kwargs):
super(BaseModel, self).__init__(*args, **kwargs)
# manager
objects = BaseModelManager()
all_objects = BaseModelManager(include_tombstoned=True)
This way models can reference Model.objects when they want undeleted items
and Model.all_objects when they want to included deleted items.
We now have a situation where we want a ForeignKey, which uses objects, to
use all_objects instead.
That is instead of this:
ref_member = models.ForeignKey(Member, related_name='+', null=True,
blank=True, on_delete=models.CASCADE)
Do something like this:
ref_member = models.ForeignKey(Member, *queryset=Member.all_objects.all()*,
related_name='+', null=True, blank=True, on_delete=models.CASCADE)
Is there any way to do the equivalent of this?
thanks
