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)?
