Re: if statement in django

It appears that you might have an indentation problem within the else:
statement of calc_total_price function.

Re: if statement in django

[Anthony Smith]

thanks now  but getting the following error

File "/home/tony/Documents/stockapp/stock/models.py" in save
  128. self.total_price = self.calc_total_price()
File "/home/tony/Documents/stockapp/stock/models.py" in calc_total_price
  124. amount_price = (self.estimated_total_weight * self.sale_kg)

have attached the code if you have time if not dont worry

def calc_estimated_total_weight(self):
amount = 0
if self.sale_head <= 0:
amount = (self.number * self.estimated_weight_hd)
return amount
def save(self):
self.estimated_total_weight = self.calc_estimated_total_weight()
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:
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()

 def __unicode__(self):
return self.buyer

cheers

Anthony,

In your first function, when the if condition evaluates to False it not 
return anything.


A possible version is:

def calc_estimated_weight_total(self):
if self.sale_head <= 0:
amount = self.number * self.estimated_weight_hd
else:
amount = 0  # (or your default value or other code to calculate 
amount)

return amount

Another version

def calc_estimated_weight_total(self):
amount = 0
if self.sale_head <= 0:
amount = self.number * self.estimated_weight_hd
return amount

Both versions will return a value not matter whether the test condition 
evaluates to True or False. The second version assumes the default value 
is 0
