Question

I’m working on a calendar via Python’s HTMLCalendar and Django. The functions I’m using to input data into the calendar are showing up as unbound, and therefore not working.

Here’s the calendar code:

from www.wednesday.models import Event
import calendar
e = Event()
class EventCal(calendar.HTMLCalendar):

    def formatday(self, day, weekday):
        if day == 0:
            return '<td class="noday">&nbsp;</td>' # Day outside month
        if day == e.dd():
            return '<td class="%s">%d</p><a href=\"%s\" target=\"_blank\">%s</a></td>' % (self.cssclasses[weekday], day, e.link(), e.res())
        else:
            return '<td class="%s">%d</td>' % (self.cssclasses[weekday], day)

class rendCal:
    c = EventCal(calendar.SUNDAY)

Here’s my models.py:

from django.db import models

class Event(models.Model):
    Restaurant = models.CharField(max_length=200)
    LinkURL = models.CharField(max_length=200)
    created = models.DateTimeField(auto_now_add=True)
    DateDay = models.IntegerField(max_length=2)

    def dd(self):
        return '%i' % self.DateDay

    def link(self):
        return '%s' % self.LinkURL

    def res(self):
        return '%s' % self.Restaurant

And lastly, my views.py:

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

def calendar(request):
    now = dt.datetime.now()
    cal = rendCal.c.formatmonth(now.year, now.month)
    return render_to_response('cal.html', {'calendar': cal})

Everything works except for the functions from Event that are called inside the EventCal class.

Obviously I’m quite new at this.

Okay, @Marcin asked for an error, this is what I’m seeing, also I corrected the capitalization.

TypeError at /calendar/
unbound method dd() must be called with Event instance as first argument (got nothing instead)
cal.py in formatday, line 9

The environment variables in EventCal from Event are showing up blank, I’m pretty sure that’s why I’d been getting the needs int not str error. When I change e.dd() to a static number, it returns everything but e.link() and e.res().

Answer 1

dd() is a method of an instance of the class.

You call it like this:

e = Event()
x = e.dd()

You can’t apply dd to Event itself.

I am not sure what exactly you are trying to do, so I am not sure how you need to modify your code.
