code: def permalink(func):
      
      def inner(*args, **kwargs):
          return app_reverse(*func(*args, **kwargs))
      return wraps(func)(inner)
docs: Decorator that calls app_reverse()
      Use this instead of standard django.db.models.permalink if you want to
      integrate the model through ApplicationContent. The wrapped function
      must return 4 instead of 3 arguments::
          class MyModel(models.Model):
              @appmodels.permalink
              def get_absolute_url(self):
                  return ('myapp.urls', 'model_detail', (), {'slug': self.slug})
