    copied!<p>I want to refresh a div tag in Django that contains temperature data. The data is fetched every 20 seconds. So far I have achieved this using these functions:</p> <pre><code>function refresh() { $.ajax({ url: '{% url monitor-test %}', success: function(data) { $('#test').html(data); } }); }; $(function(){ refresh(); var int = setInterval("refresh()", 10000); }); </code></pre> <p>And this is my urls.py:</p> <pre><code>urlpatterns += patterns('toolbox.monitor.views', url(r'^monitor-test/$', 'temperature', name="monitor-test"), url(r'^monitor/$', 'test', name="monitor"), ) </code></pre> <p>views.py:</p> <pre><code>def temperature(request): temperature_dict = {} for filter_device in TemperatureDevices.objects.all(): get_objects = TemperatureData.objects.filter(Device=filter_device) current_object = get_objects.latest('Date') current_data = current_object.Data temperature_dict[filter_device] = current_data return render_to_response('temp.html', {'temperature': temperature_dict}) </code></pre> <p>temp.html has an include tag:</p> <pre><code>&lt;table id="test"&gt;&lt;tbody&gt; &lt;tr&gt; {% include "testing.html" %} &lt;/tr&gt; &lt;/tbody&gt;&lt;/table&gt; </code></pre> <p>testing.html just contains a for tag to iterate through the dictionary:</p> <pre><code>{% for label, value in temperature.items %} &lt;td &gt;{{ label }}&lt;/td&gt; &lt;td&gt;{{ value }}&lt;/td&gt; {% endfor %} </code></pre> <p>The div is refreshed every 10 seconds and allows me to use the template system without patching it with js. However, I get repeated calls to '/monitor-test', 3-4 at the same time after a couple of minutes. Also, I was wondering if there is a better way to do this while being able to use the template system in Django. Thanks.</p>
