我可以通过修改后的HTMLCalendar（）从Django模型中迭代对象吗？

Question

This code will only retrieve a single object from the database, rather than iterate them throughout the calendar on their applicable date.

cal.py

from www.wednesday.models import Event
import calendar

class EventCal(calendar.HTMLCalendar):         
    def formatday(self, day, weekday):     
        if day == 0:
            return '<td class="noday">&nbsp;</td>' # Day outside month
        if day == int(event.dateDay.day):
            return '<td class="%s">%d</p><a href=\"%s\" target=\"_blank\">%s</a></td>' % (self.cssclasses[weekday], day, event.linkURL, event.restaurant)
        else:
            return '<td class="%s">%d</td>' % (self.cssclasses[weekday], day)

events = Event.objects.all()
for event in events:
    class rendCal():
        c = EventCal(calendar.SUNDAY)

views.py

from django.shortcuts import render_to_response
from www.wednesday.models import Event
from www.wednesday.cal import *
import datetime as dt

Months = ['', 'January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December']

now = dt.datetime.now()
mon = now.month

def calend(request):
    cal = rendCal.c.formatmonth(now.year, now.month)
    events = Event.objects.all()
    return render_to_response('cal.html', {'calendar': cal,
                                           'title': 'Win-Win Wednesday Calendar for %s' % Months[int(mon)]})

cal.html

# ...
<div id='calendar'>

<div>
</div>
{% block main %}
{{ calendar|safe }}
{% endblock %}
    </div>
</div>

Answer 1

Most of your question is murky.

And, it's printing the django tag {{ event.restaurant }} rather than the data from the model.

That's because formatday() returns the string "{{ event.restaurant }}" .

The template rendering inserts that string into the template.

The template rendering doesn't look at the data it inserts to see if the data is more template code. It just inserts data into the template.
