Страница не найдена (404). Ни одна категория не соответствует заданному запросу

Я создаю сайт электронной коммерции на фреймворке Django. При создании раздела категории, который ведет пользователя в отдельную категорию для доступа ко всем ее элементам, возникает следующая ошибка.

Page not found (404)
No Category matches the given query.
Request Method: GET
Request URL:    http://127.0.0.1:8000/search/ring/
Raised by:  store.views.category_list
Using the URLconf defined in core.urls, Django tried these URL patterns, in this order:

admin/
[name='all_product']
item/<slug:slug>/ [name='product_detail']
search/<slug:category_slug>/ [name='category_list']
The current path, search/ring/, 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.

Здесь находится файл urls.py

from django.urls import path

from . import views

app_name = 'store'

urlpatterns = [
    path('', views.all_product, name='all_product'),
    path('item/<slug:slug>/', views.product_detail, name='product_detail'),
    path('search/<slug:category_slug>/', views.category_list, name='category_list'),
]

файлviews.py

from django.shortcuts import get_object_or_404, render

from .models import  Product, Category

# Create your views here.
def categories(request):
    return {
        'categories': Category.objects.all()
    }


def all_product(request):
    product = Product.objects.all()
    return render(request, 'store/home.html', {'product': product})


def category_list(request, category_slug):
    category = get_object_or_404(Category, slug=category_slug)
    product = Product.objects.filter(category=category)
    return render(request, 'store/products/category.html', {'category': category, 'product': product})

def product_detail(request, slug):
    product = get_object_or_404(Product, slug=slug, in_stock=True)
    return render(request, 'store/products/detail.html', {'product': product})

файл models.py

from django.db import models
from django.contrib.auth.models import User
from django.urls import reverse
# Create your models here.
class Category(models.Model):
    name = models.CharField(max_length=100, db_index=True)

    def get_absolute_url(self):

    def __str__(self):
        return self.name
    
class Product(models.Model):
    category = models.ForeignKey(Category, related_name='product' , on_delete= models.CASCADE)
    created_by= models.ForeignKey(User, on_delete=models.CASCADE, related_name='product_creator' )
    title = models.CharField(max_length=100)
    author = models.CharField(max_length=100, default='admin')
    description = models.TextField(blank=True)
    image = models.ImageField(upload_to='images/')

        return reverse('store:product_detail', args=[self.slug])
    
    
    def __str__(self):
        return self.title

И файл category.html

{% extends "../base.html" %}
{% load static %}
{% block title %}
{% if category %}{{ category.name }}{% else %}Product{% endif %}
{% endblock %}
{% block content %}

  <div class="album py-5 bg-light">

        {% for product in product %}

            <div class="card-body">

          </div>
        </div>

        {% endfor %}

      </div>
    </div>
  </div>


</main>

{% endblock %}

Каждый раз, когда я ввожу '127.0.0.1:8000/search/ring' в строке url, он выдает ошибку для поиска категории, упомянутой выше, но он работает нормально для деталей продукта, т.е. '127.0.0.1:8000/item/ring'.
