Question on a resembling function on truncatewords
Hi, I started learning Django(also new to Python) and I would like to use
it in Japanese.
Since truncatewords doesn't seem working in non-English language, I tried
to create a resembling function.
I wrote the function in my Product class in my models.py:
class Product(models.Model):
title = models.CharField(max_length=220)
description = models.CharField(max_length=3000, null=True, blank=True)
price = models.DecimalField(max_digits=1000, decimal_places=2, null=True,
blank=True)
slug = models.SlugField()
timestamp = models.DateTimeField(auto_now_add=True, auto_now=False)
updated = models.DateTimeField(auto_now_add=True, auto_now=False)
active = models.BooleanField(default=True)
def __unicode__(self):
return self.title
class Meta:
ordering = ['title',]
*def shorten_words(self):*
* if len(self.description) > 20:*
* print self.desciption[0:20]*
* else:*
* print self.desciption*
and I added a code in my products.html page:
{{ product.description*.shorten_words()* }}
And it's not working..
Could you give me some advices?
Thank you!

Don't use the parenthasesbin the template. Just call
{{product.description.shorten_words}}

Hello,
Should it be?:
{{ product.shorten_words }}

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,
Sanjay

>>> You received this message b
validate answers from a detail view
I'm using a Class based Generic Detail View to show end users their answers to previous mulit-page forms. How can I use that final detail view to validate the answers? Should I not be using a Detail view or can I somehow do a conditional get to the next view based upon those answers? Right now I just have a link to the next page where they can submit all their answers from the forms. If they haven't filled out a field, I want to take them back to the form they need to go to to fix that. All it does on that final page after the datail is set a true value in the db that they are done updating their application form. -- You received this message because you are subscribed to the Google Groups "Django users" group.
