Page not found (404)

No Category matches the given query.
Request Method: GET
Request URL: http://energopribor.uz/ru/store/category/prochee-zapchasty/
Raised by: store.views.store

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

  1. ru/ admin/
  2. ru/ [name='home']
  3. ru/ store/ [name='store']
  4. ru/ store/ category/<slug:category_slug>/ [name='products_by_category']

The current path, ru/store/category/prochee-zapchasty/, matched the last one.

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.
