How to change the slug to the desired view?

Question

Django

You need to save the slug in this form
site.com/123-blablabla
. I do this in the Model

class Article(models.Model):
  title = models.CharField(max_length=120, null=False)
  slug = models.SlugField(null=False, blank=True, unique=True)

  def save(self, *args, **kwargs):
    self.slug = slugify(f"{str(self.id)}-{self.title}", lowercase=True)
    super().save(*args, **kwargs)

url

path('articles/<slug:slug>/', DetailArticleView.as_view(), name='article_detail'),

I receive
site.com/none-blablabla

Answer 1

none turns out because the slug is set before the record is saved and self.id does not work as expected, there is no record in the database yet and there is no id itself. Take advantage of signals
