Hi Pankaj,
Thank you so much!!!! You have saved my day :-) I will be able to test
it tomorrow, and I will let you know if it worked.
I tested all my previous attempts saving an existing item in Admin. But
when nothing is changed in the admin form, def save_formset is not
called......
Regards,
Rob

Hey Rob,
I tested following code and it works.
#### models.py
from django.db import models
# Create your models here.
class Ticket(models.Model):
ticketnumber = models.IntegerField()
total_amount = models.DecimalField(max_digits=7, decimal_places=2,
blank=True)
def update_total_amount(self):
total = 0
for ti in self.ticketitem_set.all():
total += ti.price * ti.amount
self.total_amount = total
self.save()
class TicketItem(models.Model):
name = models.CharField(max_length=30)
ticket = models.ForeignKey(Ticket)
price = models.DecimalField(max_digits=7, decimal_places=2)
amount = models.IntegerField()
#### admin.py
from django.contrib import admin
from tickets.models import Ticket, TicketItem
class TicketItemInline(admin.TabularInline):
model = TicketItem
class TicketAdmin(admin.ModelAdmin):
inlines = [TicketItemInline,]
def save_formset(self, request, form, formset, change):
instances = formset.save(commit=False)
for instance in instances:
instance.save()
formset.save_m2m()
instance.ticket.update_total_amount()
admin.site.register(Ticket, TicketAdmin)
I hope it helps.
Sincerely,
Pankaj Singh

Hi Pankaj,
I have tried many things today, but unfortunately I cannot get anything
working :-( Can you give me a bit more information on this issue? Any hint
would be highly appreciated!
I cannot get anything saved in the database. For testing I made this setup
(added ordernumber to the Tickets model):
class TicketAdmin(admin.ModelAdmin):
def save_formset(self, request, form, formset, change):
instances = formset.save(commit=False)
for instance in instances:
instance.ordernumber = 100
instance.save()
formset.save_m2m()
I expected the value 100 to be saved in the database....but nothing works.

Hey Rob,
You can override save_formset() method of ModelAdmin for this. Create
a method update_total_amount(self) in your Ticket Model.
class TicketAdmin(admin.ModelAdmin):
def save_formset(self, request, form, formset, change):
instances = formset.save(commit=False)
for instance in instances:
instance.user = request.user
instance.save()
formset.save_m2m()
## call update_total_amount()
instance.update_total_amount()

I have two models:
class Tickets(models.Model):
ticketnumber = models.IntegerField()
total_amount = models.DecimalField()
class TicketItems(models.Model):
name = models.Charfield(max_length=30)
ticket = models.ForeignKey(Tickets)
price = models.DecimalField()
amount = models.IntergerField()
I have an inline Adminpage were users can add TicketItems. How do I
update
the total_amount of model Tickets from all TicketItems on save (price *
amount)?
