If statement issue driving me nuts
Hi I have a small project and I have been unable to get the following statement to work. Any help would great. User inputs can either self_sale_head which is a $ value,if a $ value is not add a self.estimated_weight_hd is used to get the total weight, the code below should return a estimated_weight_total which can be used for the total sale price. All works when I add the estimated_weight_total manually. I am lost as why. def calc_estimated_weight_total(self): if self.sale_head <= 0: amount = (self.number * self.estimated_weight_hd) return amount def save(self): self.estimated_total_weight = self.calc_estimated_weight_total() super(SaleNote, self).save() -- https://mail.python.org/mailman/listinfo/python-list

Hi All I am probably doing something wrong but don't know what Any help would great Code below the calc_total does not return a estimated_total_weight if add the estimated_total_weight the rest of the code works I am at a lose as to why ? def calc_total(self): amount = 0 if self.estimated_weight_hd > 0: amount = self.number * self.estimated_weight_hd return amount def save(self): self.estimated_total_weight = self.calc_total() super(SaleNote, self).save() def calc_total_price(self): amount_price = 0 if self.sale_head > 0: amount_price = self.number * self.sale_head return amount_price else: if self.estimated_total_weight > 0: amount_price = self.estimated_total_weight * self.sale_kg return amount_price def save(self): self.total_price = self.calc_total_price() super(SaleNote, self).save() thanks anthony -- https://mail.python.org/mailman/listinfo/python-list
