{% endif %}

and code pagination in views.py:

    paginator = paginator(queryset_list, 2) # show 2 contacts per page  page = request.get.get('page') try:     queryset = paginator.page(page) except pagenotaninteger:     # if page not integer, deliver first page.     queryset = paginator.page(1) except emptypage:     # if page out of range (e.g. 9999), deliver last page of results.     queryset = paginator.page(paginator.num_pages)  index = queryset.number -1 max_index = len(paginator.page_range) start_index = index - 5 if index <= max_index - 5 else 0 end_index = index + 5 if index <= max_index - 5 else max_index page_range = paginator.page_range[start_index:end_index]
