Page not found (404)

Request Method: GET
Request URL: https://cmkdelta.ru/service/nerazrushayushij-kontrol/None

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

  1. home/
  2. service/
  3. production/
  4. admin/
  5. service/ <slug:slug>/ [name='service_detail']
  6. production/
  7. projects/
  8. personal/
  9. vacancy/
  10. ckeditor/
  11. [name='home_page']
  12. <slug:slug>/ [name='page_name']
  13. ^media/(?P<path>.*)$
  14. ^static/(?P<path>.*)$

The current path, service/nerazrushayushij-kontrol/None, 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.
