python - django 1.9 slug field is not working for foreign language -

i building post app, automatically creates slug post title. if there foreign language in title, slug not getting generated.

i have gone through of answers here, it's not helping much. missing in below ?

class post(models.model):     title = models.charfield(max_length=120)     slug = models.slugfield(unique=true, allow_unicode=true)     content = models.textfield()  def create_slug(instance, new_slug=none):     slug = slugify(instance.title)     if new_slug not none:         slug = new_slug      qs = post.objects.filter(slug=slug).order_by("-id")     exists = qs.exists()     if exists:         new_slug = "%s-%s" %(slug, qs.first().id)         return create_slug(instance, new_slug=new_slug)      return slug  def pre_save_post_receiver(sender, instance, *args, **kwargs):     if not instance.slug:         instance.slug = create_slug(instance) 

added below in settings.py:

allow_unicode_slugs = true 

you need tell slugify should allow unicode, too. see docs.

def create_slug(instance, new_slug=none):     slug = slugify(instance.title, allow_unicode=true) 

also, careful: default max_length slugfield is 50 characters. converting long title may result in slug long slugfield , raise exception.
