class Answer_Category(models.Model):
    title = models.CharField(max_length=200)
    url = models.CharField(max_length=200,blank=True, null=True)
    parent = models.ForeignKey('Answer_Category',blank=True, null=True)
    description=models.CharField(max_length=200,blank=True, null=True)

    published=models.BooleanField(default=True)
    position=models.IntegerField(default=0)

    def __str__(self):
        return self.title

    def save(self, *args, **kwargs):
        url=slugify(self.title, 'ru')
