This. And in the desciption() method, you want to do "return
self.description[0:20] and not print..." - print will just print the
output in the console at that point - you need to "return" the value
from the method.
So:
def shorten_words(self):
if len(self.description) > 20:
return self.desciption[0:20]
else:
return self.desciption
That, and {{ product.shorten_words }} in your template should do the trick.
All the best,
