Hi Doug,
Thanks for your reply. I've been trying to get something together to
see if I can figure this all out. In the end I came up with something
like this (so far):
from myproject.shop.models import Product
from django import template
register = template.Library()
def get_latest_products(parser, token):
# Get list of products by date.
latestProducts = Product.objects.all().order_by('pub_date')[:5]
return latestProductsNode()
class latestProductsNode(template.Node):
def __init__(self):
# Get list of products by date.
self.latestProducts =
Product.objects.all().order_by('pub_date')[:5]
def render(self, context):
return self.latestProducts
register.tag('latest_products', get_latest_products)
Something tells me this is not the way to go about what I want to do.
Anyone care to give me any pointers on this?
Thanks,
James
