Re: how to save in inline form total sum

[Collin Anderson]

Hello,

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 :(


It's probably because ModelA is saved before the individual ModelB's.

You could calculate this _after_ the ModelB inlines(?) have been saved 
using the save_related hook.

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

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

Re: how to save in inline form total sum

[carlos]

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

Re: how to save in inline form total sum

[Collin Anderson]

Hello,

I'm not sure what you're trying to do, but to fix the None error set 
default=0 on the total columns.

Or do something like this:
self.total_men = (self.total_men or 0) + (self.men or 0)

Thanks,
Collin

how to save in inline form total sum

[carlos]

Hi, i need sum inlines field but i no have idea

example for more clean, i have 2 models

in models.py i have:

class ModelA(models.Model):
field1 = charfield(...)
field2 = integeterfield()
.

CHOICE_TYPE = ((1,"option1"),(2,"option2"),(3,"option3"))

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 admin.py :

class ModelBInline(admin.TabularInline):
model = ModelB
extra = 3
max_num = 3

class ModelAAdmin(admin.ModelAdmin)
inlines = [ModelBInline]


admin.site.register(ModelA, ModelAAdmin)

but this override save not working, this error when save datas
unsupported operand type(s) for +=: 'NoneType' and 'int'
and the line error is this:   self.total_men += self.men


any idea for this working.

Cheers
