I'm trying to make a small modification to django lfs project, that will allow me to deactivate products with no stocks. Unfortunatelly I'm just beginning to learn python, so I have big trouble with its syntax. That's what I'm trying to do. I'm using method 'has_variants' which returns true if product has any. Then I'm building a list from variants for this product. Next for every product in this list (I've called it 'set') I check it's stock and set bool variable 'inactive' to true if product has no stocks and to false if there are any. Finally if 'inactive' is false I'm setting self.active to 0. Code fails in line with:
set[] = s
How to correct it ?
def deactivate(self):
"""If there are no stocks, deactivate the product. Used in last step of checkout.
"""
if self.has_variants():
for s in self.variants.filter(active=True):
set[] = s
for var in set:
if var.get_stock_amount() == 0:
inactive = True
else:
inactive = False
else:
if self.get_stock_amount() == 0:
inactive = True
if inactive:
self.active = False
return 0
