It sounds like you're confused about how to add more than one piece of
information to a template. When you render a template, the template is
given a context, which is a Python dict object. A dict is a bunch of
key-value pairs. So, right now, you're probably doing something like:
return render_to_response('path/to/template.html', {'items': items})
Where items is a list of item objects. You can simply add more key-value
pairs to the dict to add your counts:
items_25_to_50_count = Item.objects.filter(price__gte=25,
price__lte=50).count()
return render_to_response('path/to/template.html',
{'items': items, 'items_25_to_50_count': items_25_to_50_count})
Hopefully this helps with your question.
