Hi +Collin the idea is sum all data for example de model is
class ModelB(models.Model):
choice = models.Integerfield(choices='CHOICE_TYPE')
men = models.IntegerField()
women = models.IntegerField()
total_men = integerField(editable=False)
total_women = integerField(editable=False)
fk_model_a = fk(ModelA)
def save(self, *args, **kwargs): #this is for sum all 3 data put in
admin inlines
self.total_men += self.men
self.total_women += self.women
super(ModelB, self).save(*args, **kwargs)
in the admin look liked this:
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
for this reason i create 2 field more
total_men = integerField(editable=False)
total_women = integerField(editable=False)
and create the override save method
def save(self, *args, **kwargs): #this is for sum all 3 data put in admin
inlines
self.total_men += self.men
self.total_women += self.women
super(ModelB, self).save(*args, **kwargs)
but no working :(
any idea to save the sums of the inlines options
Cheers
