Data Model:
class A(models.model):
desc: model.CharField()
class B(models.model):
a: model.ForeignKey('A')
desc: models.CharField()

num_a
from B group by a) as x;
I've tried this:
result
Tengo el siguiente modelo de datos:
class A(models.model):
desc: model.CharField()
class B(models.model):
a: model.ForeignKey('A')
desc: models.CharField()

select max(num_a) as max_num_a from (select a, count(desc) as num_a
from B
Talla.objects.filter(tallaje=self.padre.tallaje) but it doesn't work.
