Почему шаблон не распознает поле моих моделей?

У меня есть приложение под названием ecommerce, и я уже создал базу данных. и все, что мне осталось сделать, это создать шаблон. В шаблоне я попытался создать динамическую панель навигации под названием "Categories"; Но когда я пишу "{{object.category}}" в цикле 'for', это не работает. Помогите, если знаете, где проблема, спасибо.

это моя модель:

from django.db import models

class CategoryManager(models.Manager):
def active(self):
    return self.filter(status=True)

class ProductManager(models.Manager):
    def published(self):
        return self.filter(status='p')

class Category(models.Model):
    name = models.CharField(max_length=200, verbose_name = "title")
    slug = models.SlugField(max_length=100, unique=True, verbose_name = "slug")
    status = models.BooleanField(default=True, verbose_name= "to be displayed?")

    class Meta:
        verbose_name = "category"
        verbose_name_plural = "categories"

    def __str__(self):
        return self.name

    objects = CategoryManager()

class Product(models.Model):
    CURRENCY_CHOICES = (
        ('$', 'Dollar'),
        ('€', 'Euro'),
    )
    STATUS_CHOICES = (
        ('p', 'published'),
        ('d', 'drafted'),
    )
    name = models.CharField(max_length=200, unique=True, verbose_name="product")
    category = models.ForeignKey(Category, on_delete=models.SET_NULL, null=True)
    description = models.TextField(null=True, verbose_name = "description")
    thumbnail = models.ImageField(upload_to="images", verbose_name="image")
    slug = models.SlugField(max_length=100, unique=True, verbose_name="slug")
    price = models.DecimalField(decimal_places=2, max_digits=10)
    currency = models.CharField(max_length=1, choices=CURRENCY_CHOICES, verbose_name="currency")
    status = models.CharField(max_length=1, choices=STATUS_CHOICES, default="p", verbose_name="status")
    newprice = models.DecimalField(decimal_places=2, max_digits=10, null=True, blank=True)
    star = models.CharField(max_length=5, null=True, blank=True)

    class Meta:
        verbose_name = "product"
        verbose_name_plural = "products"
        ordering = ["-price"]

    def __str__(self):
        return self.name

    objects = ProductManager()

вот мое мнение:

from django.shortcuts import render, get_object_or_404
from django.db import models
from django.contrib.auth.models import User
from .models import Product, Category
from django.views.generic import ListView, DetailView, TemplateView

class ProductList(ListView):
    template_name = "blog/product_list.html"
    model = Product
    queryset = Product.objects.published()

class ProductDetail(DetailView):
    def get_object(self):
        slug = self.kwargs.get('slug')
        return get_object_or_404(Product.objects.published(), slug=slug)

class PopularProductList(ListView):
    template_name = "blog/popular_product_list.html"
    model = Product
    queryset = Product.objects.published()

class CategoryList(ListView):
    template_name = "blog/category_list.html"

    def get_queryset(self):
        global category
        slug = self.kwargs.get('slug')
        category = get_object_or_404(Category.objects.active(), slug=slug)
        return category.Products.published()

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context["category"] = category
        return context

def about(request):
    return render(request, "blog/about.html")

и это часть моего шаблона:

<nav class="navbar navbar-expand-lg navbar-light bg-light">
    <div class="container px-4 px-lg-5">
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation"><span class="navbar-toggler-icon"></span></button>
        <div class="collapse navbar-collapse" id="navbarSupportedContent">
            <ul class="navbar-nav me-auto mb-2 mb-lg-0 ms-lg-4">
                <li class="nav-item"><a class="nav-link active" aria-current="page" href="{% url 'home' %}">Home</a></li>
                
                <li class="nav-item"><a class="nav-link" href="{% url 'about' %}">About</a></li>
                        <li class="nav-item dropdown">
                            <a class="nav-link dropdown-toggle" id="navbarDropdown" href="#" role="button" data-bs-toggle="dropdown" aria-expanded="false">Categories</a>
                            <ul class="dropdown-menu" aria-labelledby="navbarDropdown">
                                {% for object in object_list %}
                                <li><a class="dropdown-item" href="#">{{object.category}}</a></li>
                                {% endfor %}
                            </ul>
                        </li>
            </ul>
        </div>
    </div>
    </nav>
