Description

the following model can not be saved in admin:

class CourseCollection(models.Model):
    course_type=models.ForeignKey(CourseType)
    days=models.PositiveSmallIntegerField(_("Tage"))
    popup_text=models.TextField(_("Popup Text"))
    info=models.CharField(_("Zusatz Info"),maxlength=100)
    prize=models.PositiveSmallIntegerField(_("Preis"))
    class Admin:
        list_display = ('course_type','type','days','prize')
        list_filter = ('course_type','days','prize')
        search_fields = ('popup_text','info')
    class Meta:
        verbose_name=_('Kurs Gruppe')
        verbose_name_plural=_('Kurs Gruppen')
    def __unicode__(self):
        return "%s(%s)" %(self.course_type,unicode(self.type))
        
class Course(models.Model):
    course_collection=models.ForeignKey(CourseCollection,edit_inline=models.TABULAR,num_in_admin=40)
    code=models.CharField(_("Code"),maxlength=8,unique=True)
    location=models.ForeignKey(Location,core=True)
    start_date=models.DateField(_("Start Datum"),default=datetime.date.today)
    examination_date=models.DateField(_(u"Prüfungs Datum"),null=True,blank=True)

the problem lies with the code field in the Course model. As long as there is a unique=True it will raise the following exception:

{{
