Haystack Search Pager

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

  1. Create a templatetag:

    @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:

    {% 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.
