Изображения не отображаются в слайдере на сайте Django

Я выполнил все необходимые шаги для отображения слайдера изображений в моем проекте Django-сайта. Но изображения не отображаются, не выдавая никаких ошибок, я думаю, что есть ошибка в моем home.html файле Django кода. Для этого руководство меня. Спасибо за ваше доброе ожидание

views.py

from django.shortcuts import get_object_or_404, render

# Create your views here.
def cars(request):
    cars = Car.objects.order_by('-created_date')
    data = {
        'cars': cars,
        }
    return render(request, 'cars/cars.html', data)
def car_detail(request, id):
    single_car = get_object_or_404(Car, pk=id)
    data = {

    all_cars = Car.objects.order_by('-created-date')
    data = {
        'all_cars' : all_cars,
    } 

    return render(request, 'cars/car_detail.html', data)

home.html Я думаю, что мой код Django в home.html содержит ошибки. помогите в этом вопросе.

all_cars = Car.objects.order_by('-created-date')

all_cars = Car.objects.order_by('-created_date')
