Added pagination

Sept. 24, 2017, Jochen

Implementing pagination was also quite easy. Since I'm using class based views, I only had to add the attribute paginated_by = 5 to my view class and this snippet to my blogpost_list.html template:

{% verbatim %}

<nav aria-label="pagination">
  <ul class="pagination">
    {% if page_obj.has_previous %}
      <li class="page-item"><a class="page-link" href="?page={{ page_obj.previous_page_number }}">previous</a><li>
    {% endif %}
    {% if page_obj.has_next %}
      <li class="page-item"><a class="page-link" href="?page={{ page_obj.next_page_number }}">next</a></li>
    {% endif %}
  </ul>
</nav>

{% endverbatim %}
