Example views

This is an example to break up long lists into several pages. It uses one url (get) variable "?offset=xxx"

def item_index(request):
 offset = int(request.GET.get("offset", 0))
 item_count = items.get_count()
 limit=50
 if (offset + limit) < (item_count - 1):
 new_offset = offset + limit
 else:
 limit= (item_count - offset)
 new_offset = False
 latest_item_list = items.get_list(order_by=['-date'], offset=offset, limit=limit)
 return render_to_response('item/list', {
 'latest_item_list': latest_item_list,
 'item_count': item_count,
 'from': offset + 1,
 'to': limit,
 'offset': new_offset,
 })

This is the template I use. It’s a very simple one, only displaying a row counter and a date column:

{% if latest_item_list %}
 <p>
 {% if item_count %}
 There {% ifequal item_count "1" %}is{% endifequal %}
 {% ifnotequal item_count "1" %}are{% endifnotequal %}
 {{ item_count }} item{{ item_count|pluralize }}.
 {% else %}
 No itemcount provided to the template
 {% endif %}
 You are looking at {{ from }} to {{ to }}. 
 </p>
 <table width="100%">
 <tr>
 <th style="text-align:left;">#</th><th style="text-align:left;">Date</th>
 </tr>
 {% for item in latest_item_list %}
 <tr>
 <td>{{ forloop.counter }}</td>
 <td>{{ item.date }}</td>
 </tr>
 {% endfor %}
 </table>
{% else %}
 <p>There are no items available.</p>
{% endif %}
<p>
{% if offset %}
 <a href="?offset={{ offset }}">next</a>
{% else %}
 End of list.
{% endif %}
</p>
