Vittorino, this is not related to your initial question and you must
consider that the format() returns always a string. And why do you use
format() in total_no_vat()?
I would separate the "total":
...
def total_no_vat(self):
return self.total_income + self.total_fee
def total(self):
return self.total_no_vat() * 1.21
def formatted_total(self):
return format(self.total(), settings.DECIMAL_SEPARATOR, 2)
now you can use formatted_total in your list_display
