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>
