I have a custom manager class that has use_for_related_field set to true,
and I set it to be the default manager in my model. But when I make a
query using select_related on the related field, I seem to get a plain
queryset, not my custom one. Here's a quick sketch of what I'm doing:
class MyQuerySet(models.query.QuerySet):
@property
def foo(self):
return self.filter(foo=True)
class MyManager(models.Manager):
use_for_related_field = True
def get_query_set(self):
return MyQuerySet(self.model)
class Widget(models.Model):
thingies = models.ManyToManyField(Thingy, related_name='widgets')
objects = MyManager()
When I run this query:
Thingy.objects.select_related('widgets').foo
Django tells me that
AttributeError: 'QuerySet' object has no attribute 'foo'
Is this something I should expect to work? I seem to have reached the thin
edge of both documentation and discussions.
