What I'm trying to do is grab the site sponsors according to site
section. Some sponsor section A, others section B, etc.
As I have it, I'm returning a list of sponsors filtered by section.
This works, but it seems dumb, since I'm always returning a list of one
(section). In my template, which then forces me to use two loops in the
template, one for the section, and one for the sponsors associated with
it.
What I want to do is just return the appropriate section object, then
loop through it for the sponsors.
Here's the template tag I have, which I call with something like {%
get_sponsors_list sectionA as sponsor_list %}
from django import template
from gretschpages.sponsors.models import *
register = template.Library()
class SponsorsListNode(template.Node):
def __init__(self, section, varname):
self.section = section
self.varname = varname
def __repr__(self):
return "<Sponsor Node>"
def render(self, context):
context[self.varname] =
Section.objects.all().order_by('?').filter(section=self.section)
return ''
class DoGetSponsorsList:
"""
{% get_sponsors_list as sponsors_list %}
"""
def __init__(self, tag_name):
self.tag_name = tag_name
def __call__(self, parser, token):
bits = token.contents.split()
if len(bits) != 4:
raise template.TemplateSyntaxError, "'%s' tag takes three
arguments" % bits[0]
if bits[2] != "as":
raise template.TemplateSyntaxError, "second argument to
'%s' tag must be 'as'" % bits[0]
return SponsorsListNode(bits[1], bits[3])
register.tag('get_sponsors_list',
DoGetSponsorsList('get_sponsors_list'))
