Real example

Lets assume you have event class in models

eventobj=events.objects.all() // list you objects of events class

paginator = Paginator(eventobj, 2)

try:
page = int(request.GET.get(‘page’,'1′))
except ValueError:
page = 1
try:
eventobj = paginator.page(page)
except(EmptyPage, InvalidPage):
eventobj = paginator.page(paginator.num_pages)
return render_to_response(“event.html”,{‘eventobj’:eventobj,’today’:today.strftime(“%B %d %Y %A”)})

event.html

<div >
{% if eventobj %}
<div class=”event”>
<div style=”color:red”>{{ today }} </div>
{% for name in eventobj.object_list %}
<div class=”eventname”><b>{{ name.title }}</b></div>
<div class=”eventaddress”>{{ name.address }}</div>
<div class=”eventdesc”>{{ name.description }}</div>
{% endfor %}
</div>
{% endif %}
</div>
<div class=”paging”>
<table align=”center”>
<tr>
<td>
{% if eventobj.has_previous %}
<a href=”?page={{ eventobj.previous_page_number}}” style=”text-decoration:none;color:#000000;” ><img src=”/static/images/article_previous.gif” border=”0″/>&nbsp;&nbsp;prev&nbsp;&nbsp;&nbsp;|&nbsp;&nbsp;</a>
{% endif %}
</td>
<td>
Page {{ eventobj.number }} of {{ eventobj.paginator.num_pages }}
</td>
<td>
{% if eventobj.has_next %}
<a href=”?page={{ eventobj.next_page_number }}” style=”text-decoration:none;color:#000000;”>&nbsp;&nbsp;&nbsp;|&nbsp;&nbsp;next&nbsp;&nbsp;<img src=”/static/images/article_next.gif” border=”0″/></a>{% endif %}
</tr>
</table></div>
