我想从django中的数据库中仅获取特定类别的产品（女性）产品

Question

 {% regroup products by categories as products_by_category %}
    {% for c in products_by_category %}
       <h1>{{c.grouper}}</h1>
       <ul>
        {% for p in c.list %}
            <li>{{p.name}}</li>
            <li> <img src="{{ MEDIA_URL }}{{ p.image.url }}" alt="IMG-PRODUCT" height="290" width="190"></li>
            <li>{{ p.price }}</li>
        {% endfor %}
       </ul>
    {% endfor %}

这是我的Views.py

def product_list_women(request, category_slug=None):
    category = None
    categories = Category.objects.filter(name='women', slug='women')
    products = Product.objects.filter(available=True)
    if category_slug:
        category = get_object_or_404(Category, slug=category_slug)
        products = products.filter(category=categories)
    return render(request, 'product_women.html',{'category': category,'categories':categories,'products':products})

这是我的models.py文件

class Category(models.Model):
    name = models.CharField(max_length=150, db_index=True)
    slug = models.SlugField(max_length=150, unique=True ,db_index=True)
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)

    class Meta:
        ordering = ('name', )
        verbose_name = 'category'
        verbose_name_plural = 'categories'

    def __str__(self):
        return self.name

    def get_absolute_url(self):
        return reverse('demo:category', args=[self.slug])

    def get_products(self):
        return Product.objects.filter(category=self)


class Product(models.Model):
    category = models.ForeignKey(Category, related_name='products', on_delete=models.CASCADE)
    name = models.CharField(max_length=100, db_index=True)
    slug = models.SlugField(max_length=100, db_index=True)
    description = models.TextField(blank=True)
    price = models.DecimalField(max_digits=10, decimal_places=2)
    available = models.BooleanField(default=True)
    stock = models.PositiveIntegerField()
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)
    image = models.ImageField(upload_to='products/%Y/%m/%d', blank=True)

    class Meta:
        ordering = ('name', )
        index_together = (('id', 'slug'),)

    def __str__(self):
        return self.name

    def get_absolute_url(self):
        return reverse('demo:product_detail', args=[self.id, self.slug])

我想仅列出女性产品而不是所有类别的产品类别。我想制作显示产品的页面，当我点击该类别时。此代码显示所有产品类别明智。我怎么能这样做？
