Using the URLconf defined in backend.urls, Django tried these URL patterns, in this order:

  1. admin/
  2. [name='home']
  3. profile/? [name='profile']
  4. ob_avtore/?
  5. kniga/?
  6. ochnaya-programma-russkaya-model-kontrollinga/?
  7. online-programma-russkaya-model-kontrollinga/?
  8. konsalting/?
  9. raspisanie/?
  10. contacts/?
  11. investitsionnaya-deyatelnost/?
  12. spasibo/?
  13. users/

The current path, prakticheskie-materialy-knigi/2333-prochie-vidy-stoimostnoy-ocenki-elementov, didn't match any of these.

You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.
