     1== Example views ==
     2
     3This is an example to break up long lists into several pages. It uses one url (get) variable "?offset=xxx"
     4{{{
     5def item_index(request):
     6    offset = int(request.GET.get("offset", 0))
     7    item_count = items.get_count()
     8    limit=50
     9    if (offset + limit) < (item_count - 1):
     10        new_offset = offset + limit
     11    else:
     12        limit= (item_count - offset)
     13        new_offset = False
     14    latest_item_list = items.get_list(order_by=['-date'], offset=offset, limit=limit)
     15    return render_to_response('item/list', {
     16        'latest_item_list': latest_item_list,
     17        'item_count': item_count,
     18        'from': offset + 1,
     19        'to': limit,
     20        'offset': new_offset,
     21    })
     22}}}
     23
     24This is the template I use. It’s a very simple one, only displaying a row counter and a date column:
     25
     26{{{
     27{% if latest_item_list %}
     28    <p>
     29    {% if item_count %}
     30        There {% ifequal item_count "1" %}is{% endifequal %}
     31        {% ifnotequal item_count "1" %}are{% endifnotequal %}
     32        {{ item_count }} item{{ item_count|pluralize }}.
     33    {% else %}
     34        No itemcount provided to the template
     35    {% endif %}
     36    You are looking at {{ from }} to {{ to }}.
     37    </p>
     38    <table width="100%">
     39        <tr>
     40            <th style="text-align:left;">#</th><th style="text-align:left;">Date</th>
     41        </tr>
     42    {% for item in latest_item_list %}
     43        <tr>
     44            <td>{{ forloop.counter }}</td>
     45            <td>{{ item.date }}</td>
     46        </tr>
     47    {% endfor %}
     48    </table>
     49{% else %}
     50    <p>There are no items available.</p>
     51{% endif %}
     52<p>
     53{% if offset %}
     54    <a href="?offset={{ offset }}">next</a>
     55{% else %}
     56    End of list.
     57{% endif %}
     58</p>
     59}}}
