ordering=['Name']
abstract=True
class Comment(models.Model):
CommentSchoolNum=models.ForeignKey('People')
CommentWord=models.TextField()
CommentTime=models.DateField()
def __unicode__(self):
return self.CommentWord
why I cannot use such sentense:
s=People.objects.filter(Position='A')
s.comment_set.all()
The django says that the queryset does not have the attribution
comment_set.Why?
