Как разделить категории на разных страницах в Python и Django?
Мне нужна помощь с моим проектом сайта электронной коммерции. У меня будет 5 категорий в выпадающем меню. Я хочу видеть разные категории на разных страницах, когда я нажимаю на категорию в выпадающем меню. Сейчас я вижу все товары на главной странице, а когда я нажимаю на категорию BOOKS, я вижу книги на главной странице, но я не хочу этого. Я хочу использовать главную страницу для объявлений, а когда я нажимаю на категорию, я хочу видеть ее на другой странице. Как я могу разделить их?
Мои модели:
class Category(models.Model):
name = models.CharField(max_length=250, unique=True)
slug = models.SlugField(max_length=250, unique=True)
description = models.TextField(blank=True)
class Meta:
ordering = ('name',)
verbose_name = 'category'
verbose_name_plural = 'categories'
def get_url(self):
return reverse('products_by_category', args=[self.slug])
def __str__(self):
return str(self.name)
# Model: Product
# Model: Cart
class Add(models.Model):
image = models.ImageField(upload_to='add', blank=True)
image1 = models.ImageField(upload_to='add', blank=True)
image2 = models.ImageField(upload_to='add', blank=True)
class Meta:
verbose_name = 'add'
verbose_name_plural = 'adds'
def __str__(self):
return str(self.image)
class Product(models.Model):
name = models.CharField(max_length=250, unique=True)
slug = models.SlugField(max_length=250, unique=True)
description = models.TextField(blank=True)
category = models.ForeignKey(Category, on_delete=models.CASCADE)
price = models.DecimalField(max_digits=10, decimal_places=2)
image = models.ImageField(upload_to='product', blank=True)
image1 = models.ImageField(upload_to='product', blank=True)
image2 = models.ImageField(upload_to='product', blank=True)
image3 = models.ImageField(upload_to='product', blank=True)
stock = models.IntegerField()
available = models.BooleanField(default=True)
created = models.DateTimeField(auto_now_add=True)
updated = models.DateTimeField(auto_now=True)
class Meta:
ordering = ('name',)
verbose_name = 'product'
verbose_name_plural = 'products'
def get_url(self):
return reverse('product_detail', args=[self.category.slug, self.slug])
def __str__(self):
return str(self.name)
# Model: Cart
class Cart(models.Model):
cart_id = models.CharField(max_length=250, blank=True)
date_added = models.DateField(auto_now_add=True)
class Meta:
db_table = 'Cart'
ordering = ['date_added']
Мое мнение:
def home(request, category_slug=None):
category_page = None
products_list = None
if category_slug != None:
category_page = get_object_or_404(Category, slug=category_slug)
products_list = Product.objects.filter(category=category_page, available=True)
else:
products_list = Product.objects.all().filter(available=True)
paginator = Paginator(products_list, 8)
try:
page = int(request.GET.get('page', '1'))
except:
page = 1
try:
products = paginator.page(page)
except(EmptyPage, InvalidPage):
products = paginator.page(paginator.num_pages)
return render(request, 'home.html', {'category': category_page, 'products': products})
def productPage(request, category_slug, product_slug):
try:
product = Product.objects.get(category__slug=category_slug, slug=product_slug)
except Exception as e:
raise e
if request.method == 'POST' and request.user.is_authenticated and request.POST['content'].strip() != '':
Review.objects.create(product=product,
user=request.user,
content=request.POST['content'])
reviews = Review.objects.filter(product=product)
return render(request, 'product.html', {'product': product, 'reviews': reviews})
def _cart_id(request):
cart = request.session.session_key
if not cart:
cart = request.session.create()
return cart
def add_cart(request, product_id):
product = Product.objects.get(id=product_id)
try:
cart = Cart.objects.get(cart_id=_cart_id(request))
except Cart.DoesNotExist:
cart = Cart.objects.create(
cart_id=_cart_id(request)
)
cart.save()
try:
cart_item = CartItem.objects.get(product=product, cart=cart)
if cart_item.quantity < cart_item.product.stock:
cart_item.quantity += 1
cart_item.save()
except CartItem.DoesNotExist:
cart_item = CartItem.objects.create(
product=product,
quantity=1,
cart=cart
)
cart_item.save()
return redirect('cart_detail')
Мой URL :
urlpatterns = [
path('', views.home, name='home'),
path('category/<slug:category_slug>', views.home, name='products_by_category'),
