I'm trying to write my first django app, so maybe my problem is stupid.
But I have problems in using relationships in my models.
My models.py looks like this:
# -*- coding: utf-8 -*-
from django.db import models
from django.contrib.auth.models import User
import datetime
class Kalender(models.Model):
name = models.CharField("Kalendername", max_length=100)
description = models.TextField("Beschreibung")
class Meta:
verbose_name_plural = "Kalender"
class Termin(models.Model):
in_calendar = models.ForeignKey(Kalender)
name = models.CharField("Terminname", max_length=100)
date = models.DateTimeField("Datum und Uhrzeit")
description = models.TextField("Beschreibung")
def is_today(self):
return self.date.date() == datetime.date.today()
is_today.short_description = "Termin findet heute statt?"
participants = models.ManyToManyField(User)
class Meta:
verbose_name_plural = "Termine"
Syncdb creates the tables without errors.
Next I configured the admin to include both classes:
from kalender.models import *
from django.contrib import admin
admin.site.register(Kalender)
admin.site.register(Termin)
The admin-interface for the class Kalender works fine, but Termin
produces errors:
OperationalError at /admin/kalender/termin/
(1054, "Unknown column 'kalender_termin.in_calendar_id' in 'field list'")
Traceback:
