Hi can you tried this function

class Training(models.Model):
    title = models.CharField(max_length=250)
    text = models.TextField()
    created_date = models.DateTimeField(
    auto_now_add=True, editable=False, )
    slug = models.SlugField(unique=True, editable=False, max_length=250)

    def __unicode__(self):
       return self.title

    def save(self, *args, **kwargs):
       self.slug =get_unique_slug(self.id,self.title,Training.objects)
       return super(Training, self).save(*args, **kwargs)

def get_unique_slug(id,title,obj):
    slug = slugify(title.replace('ı', 'i'))
    unique_slug = slug
    counter = 1
    while obj.filter(slug=unique_slug).exists():
       if(obj.filter(slug=unique_slug).values('id')[0]['id']==id):
           break
       unique_slug = '{}-{}'.format(slug, counter)
       counter += 1
    return unique_slug
