That method generates HTML with CSS classes. Hence you'll need the style sheet file

<div class="highlight"><pre>def load_generic_related(qs, *args):
 &quot;&quot;&quot;
 Do in 1 + M(number of content types) quries the loading
 of related object which linked via GenericForeignKey
 &quot;&quot;&quot;

items = qs.select_related(&#39;content_type&#39;)

model_map = {}
 item_map = {}

for item in items:
 model_map.setdefault(item.content_type, {})\
 .setdefault(item.object_id, []).append(item.id)
 item_map[item.id] = item

for ctype, ids in model_map.items():
 cobjects = ctype.model_class().objects.select_related(*args)\
 .filter(id__in=ids.keys())
 for obj in cobjects:
