One way I think is just like what you do: create a extra_context.
The other way is create a custom tag to create a list. Someone has
submit this patch before. http://code.djangoproject.com/ticket/1162
Or you can use a custom tag written by me to calculate the list in
template: expr tag

{% expr range(pages) as page_number %}
{% for i in page_number %}
...
{% endfor %}
