Hi, +Collin
i update my ModelA and now is this:
class ModelA(models.Model):
field1 = charfield(...)
field2 = integeterfield()
total_men = integerField(editable=False)
total_women = integerField(editable=False)
def save(self, *args, **kwargs): #this is for sum all 3 data put in
admin inlines
self.total_men = sum(map(sum, ModelB.objects.filter(choice__in =
[1,2,3], modela_id = self.id).values_list('men',)))
self.total_total_women = sum(map(sum,
ModelB.objects.filter(choice__in = [1,2,3], modela_id = self.id
).values_list('women',)))
super(ModelA, self).save(*args, **kwargs)
the only problem that is save correct total sum but a hit 2 o 3 time button
save in the admin, not first time
why? i don't know :(
any idea
Cheers
