Re: how to save in inline form total sum

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

Hello,

 

ModelB in inline

choice               men           women

option1               6                   4

option2               1                   3

option3               2                  1

i need save in other field total this sum for example men = 9  and women total is = 8

Right, it seems to me that the "total"  need to be on a separate model from the individual counts, maybe on ModelA?
