Haystack Search Pager

Mar 06, 2014 · by Tim Kamanin

To make haystack search pager place nicelly with other get parameters, we can do something like this:

1) Create a templatetag:

python

@register.simple_tag
def get_search_pager_link(request):
  params = []
  link = '?'
  for key, value in request.GET.items():
    if key != 'page':
      params.append(u'{}={}'.format(key, value))
      link += '&'.join(params)
    if len(link) > 1:
      link += '&'
  return link

2) Use it in your search pager template like this:

html

{% load core_tags %}
{% if page.has_previous or page.has_next %}
<ul class="pagination">
  {% if page.has_previous %}
    <li class="previous"><a href="{% get_search_pager_link request %}page={{ page.previous_page_number }}">previous</a></li>
  {% endif %}

  {% for pg in page.paginator.page_range %}
    {% if page.number == pg %}
      <li class="active"><a href="{% get_search_pager_link request %}page={{ pg }}">{{ pg }}</a></li>
    {% else %}
      <li><a href="{% get_search_pager_link request %}page={{ pg }}">{{ pg }}</a></li>
    {% endif %}
  {% endfor %}

  {% if page.has_next %}
    <li class="next"><a href="{% get_search_pager_link request %}page={{ page.next_page_number }}">next</a></li>
  {% endif %}
</ul>
{% endif %}

That way we'll achieve some nice functionality: search pager will play well with other GET parameters.
