I've tried low-level api, and must be missing something:
class RideNode(template.Node):
def __init__(self, varname):
self.varname = varname
def render(self, context):
if cache.get('rod'):
context[self.varname] = cache.get('rod')
else:
ride =
Ride.objects.filter(site=settings.SITE_ID).order_by('?')[:1]
cache.set('rod', ride, 30)
context[self.varname] = cache.get('rod')
return ''
