I'm trying to do render_to_response to return the worked out response of my view to an ajax call, but I get the following error, which I really don't understand ...
Internal Server Error: /schedules/calendar/2014/10/1/

I do not understand where this error came from. I call request_to_response according to the instructions in the django documentation. Here is my opinion:
def month_view(
request,
year,
month,
template='monthly_view.html',
user_id=None,
queryset=None
):
year, month = int(year), int(month)
cal = calendar.monthcalendar(year, month)
dtstart = datetime(year, month, 1)
last_day = max(cal[-1])
dtend = datetime(year, month, last_day)
if user_id:
profile = get_object_or_404(UserProfile, pk=user_id)
queryset = profile.occurrence_set
queryset = queryset._clone() if queryset else Occurrence.objects.select_related()
occurrences = queryset.filter(start_time__year=year, start_time__month=month)
def start_day(o):
return o.start_time.day
by_day = dict([(dt, list(o)) for dt,o in itertools.groupby(occurrences, start_day)])
data = {
'today': datetime.now(),
'calendar': [[(d, by_day.get(d, [])) for d in row] for row in cal],
'this_month': dtstart,
'next_month': dtstart + timedelta(days=+last_day),
'last_month': dtstart + timedelta(days=-1),
}
if request.is_ajax():
my_html = render_to_string('monthly_view.html', data)
return HttpResponse(json.dumps(my_html), content_type="application/json")
else:
raise Http404
Has anyone encountered an error like this before, or had an idea of where it came from? On the line right before the call to change the parameters for the reverse are
View_name: graphs: monthly view Args: [2014, 9] kwargs: {'User_pk': ''}
The template I'm trying to do is:
<h4>
<a href="{% url 'schedules:monthly-view' last_month.year last_month.month user_pk=object.profile.pk %}"
title="Last Month">←</a>
{{ this_month|date:"F" }}
<a title="View {{ this_month.year}}" href='#'>
{{ this_month|date:"Y" }}</a>
<a href="{% url 'schedules:monthly-view' next_month.year next_month.month user_pk=object.profile.pk %}"
title="Next Month">→</a>
</h4>
<table class="month-view">
<thead>
<tr>
<th>Sun</th><th>Mon</th><th>Tue</th><th>Wed</th><th>Thu</th><th>Fri</th><th>Sat</th>
</tr>
</thead>
<tbody>
{% for row in calendar %}
<tr>
{% for day,items in row %}
<td{% ifequal day today.day %} class="today"{% endifequal %}>
{% if day %}
<div class="day-ordinal">
<a href="{% url 'schedules:daily-view' this_month.year this_month.month day user_pk=object.profile.pk %}">{{ day }}</a>
</div>
{% if items %}
<ul>
{% for item in items %}
<li>
<a href="{{ item.get_absolute_url }}">
<span class="event-times">{{ item.start_time|time }}</span>
{{ item.title }}</a>
</li>
{% endfor %}
</ul>
{% endif %}
{% endif %}
</td>
{% endfor %}
</tr>
{% endfor %}
</tbody>
</table>
and urls.py -
from django.conf.urls import patterns, url
from .views import (
CreateSessionView, CreateListingsView, SessionsListView,
month_view, day_view, today_view
)
urlpatterns = patterns('',
url(
r'^(?:calendar/)?$',
today_view,
name='today'
),
url(
r'^calendar/(?P<year>\d{4})/(?P<month>0?[1-9]|1[012])/(?P<user_pk>\d+)/$',
month_view,
name='monthly-view'
),
url(
r'^calendar/(?P<year>\d{4})/(?P<month>0?[1-9]|1[012])/(?P<day>[0-3]?\d)/(?P<user_pk>\d+)/$',
day_view,
name='daily-view'
),
In addition, an ajax request is presented here:
<script>
function update_calendar(url) {
console.log("Calling url " + url)
$.ajax({
type: 'GET',
dataType: 'json',
url: url,
success: function(data, status, xhr) {
console.log('success')
console.log(data);
$('#schedule').html(data)
},
error: function() {
console.log('Something went wrong');
}
});
}
$(document).ready(function() {
var today = new Date();
var year = today.getFullYear();
var month = today.getMonth()+1;
var user_pk = {{ object.profile.pk }};
var url = '../schedules/calendar/'+year+'/'+month+'/'+user_id+'/';
url = "{% url 'schedules:monthly-view' year month user_pk=user_pk %}"
update_calendar(url);
$('#schedule > a').click(function(event) {
var url = $(this).attr('href');
update_calendar(url);
});
});
</script>
