Re: What's the best way to create a reusable pagination template?

Yep. My solution is a custom template tag

from django.template.defaulttags import register
from urllib.parse import urlencode

@register.simple_tag(takes_context=True)
def querystringmod(context, *args):
    """Modify current querystring:
     {% querystringmod name value [name value [...]] %}
    """
    if (len(args) % 2) !=0:
        args.append("")
    request = context['request']
    current_qs = request.GET.dict()
    current_qs.update(dict([ (args[n], args[n+1]) for n in range(0, len(args), 2) ]))
    return urlencode(current_qs)

in template

<a href="?{% querystringmod "page" page_obj.previous_page_number %}">previous</a>
