看到django-oscar網站上的案例分享如上圖，就能感受到這款電子商店的媚力，再看到下圖在Github的星級也高達5k，一定要動手下載來測試看看。

但測試過程似乎不怎麼方便，經過幾番的測試，查詢錯誤的訊息，找到相關解決方法，最後整理出下面的的套件，供大家在測試OSCAR沙盒的參考。

最後的測試結果為：

Django 3和Bootstrap 5聯手展現布農族拉芙嵐文化特色

程式碼參考網址：https://getbootstrap.com/docs/5.0/components/carousel/

1.準備三張拉芙嵐的特色照片，利用小畫家修成1920X750，儲存在shop/static/slider目錄下，並分別命名為bg1.jpg, bg2.jpg, 以及bg3.jpg。

2.把參考的程式貼在shop/templates/shop/base.html中。

使用Bootstrap5為電子購物網站換新裝

前一篇文章我們把Django升級到3.2.4版，本篇文章我們來把Bootstrap3升級為Bootstrap5，步驟如下：

1,安裝dajngo-bootstrap-v5

2.使用pip list檢查安裝的套件，發現bootstrap3以及bootstrap-v5都在shopenv環境中。

3.使用pip uninstall 命令來移除bootstrap3

5.修改設定檔django_shop_tutorial/settings.py，將bootstrap3改為bootstrap5。

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'bootstrap5',
    'shop',
    'cart',
    'orders',
    'paypal.standard.ipn',
    'payment',
]

5.修改樣版

四個步驟輕鬆升級Django最新版電子購物網站

前一篇文章：使用Django技術來建置簡易版電子購物網站

為回應讀者反應Django版本太低，應該要用新版的Django，由於原作者twtrubiks在四年前就發展這個專案-twtrubiks/django-shop-tutorial，因此必須將Django版本改成Djangle 1.11.29，才能順利編譯完成。目前Django已經升級到3.2.4，以下四個步驟升級為Django 3.2.4版。

1.修改urls.py，有兩個重點，其一是include函式的參數，其二是除了django_shop_tutorial目錄下的urls.py不需要加上設定app_name變數值，其餘的urls.py都要也就是經由include函式的urls都需要。

(1) django_shop_tutorial/urls.py

"""django_shop_tutorial URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/1.11/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  url(r'^$', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  url(r'^$', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.conf.urls import url, include
    2. Add a URL to urlpatterns:  url(r'^blog/', include('blog.urls'))
"""
from django.conf import settings

2.修改models，有兩個重點，其一是django.core.urlresolvers套件由django.urls套件取代，其二是ForeignKey參數必須要指定on_delete參數值。

(1)shop/models.py

from django.urls import reverse
from django.db import models


class Category(models.Model):
    name = models.CharField(max_length=200,
                            db_index=True)
    slug = models.SlugField(max_length=200,
                            db_index=True,
                            unique=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('shop:product_list_by_category',
                       args=[self.slug])


class Product(models.Model):
    category = models.ForeignKey(Category,
                                 related_name='products', on_delete=models.CASCADE)
    name = models.CharField(max_length=200, db_index=True)
    slug = models.SlugField(max_length=200, db_index=True)
    image = models.ImageField(upload_to='products/%Y/%m/%d',
                              blank=True)
    description = models.TextField(blank=True)
    # 台灣價錢都是整數，所以可以設定 decimal_places=0
    price = models.DecimalField(max_digits=10, decimal_places=0)
    stock = models.PositiveIntegerField()
    available = models.BooleanField(default=True)
    created = models.DateTimeField(auto_now_add=True)
    updated = models.DateTimeField(auto_now=True)

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

    def __str__(self):
        return self.name

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

(2) order/models.py

from django.db import models

from shop.models import Product


class Order(models.Model):
    first_name = models.CharField(max_length=50)
    last_name = models.CharField(max_length=50)
    email = models.EmailField()
    address = models.CharField(max_length=250)
    postal_code = models.CharField(max_length=20)
    city = models.CharField(max_length=100)
    created = models.DateTimeField(auto_now_add=True)
    updated = models.DateTimeField(auto_now=True)
    paid = models.BooleanField(default=False)

    class Meta:
        ordering = ('-created',)

    def __str__(self):
        return 'Order {}'.format(self.id)

    def get_total_cost(self):
        return sum(item.get_cost() for item in self.items.all())


class OrderItem(models.Model):
    order = models.ForeignKey(Order,
                              related_name='items', on_delete=models.CASCADE)
    product = models.ForeignKey(Product,
                                related_name='order_items', on_delete=models.CASCADE)
    # 台灣價錢都是整數，所以可以設定 decimal_places=0
    price = models.DecimalField(max_digits=10, decimal_places=0)
    quantity = models.PositiveIntegerField(default=1)

    def __str__(self):
        return '{}'.format(self.id)

    def get_cost(self):
        return self.price * self.quantity

3.修改payment/views.py，只需要將django.core.urlresolvers套件由django.urls套件取代。

from decimal import Decimal

from django.conf import settings
from django.urls import reverse
from django.shortcuts import render, get_object_or_404
from django.views.decorators.csrf import csrf_exempt
from paypal.standard.forms import PayPalPaymentsForm

from orders.models import Order


def payment_process(request):
    order_id = request.session.get('order_id')
    order = get_object_or_404(Order, id=order_id)
    host = request.get_host()
    paypal_dict = {
        'business': settings.PAYPAL_RECEIVER_EMAIL,
        'amount': '%.2f' % order.get_total_cost().quantize(
            Decimal('.01')),
        'item_name': 'Order {}'.format(order.id),
        'invoice': str(order.id),
        'currency_code': 'TWD',
        'notify_url': 'http://{}{}'.format(host,
                                           reverse('paypal-ipn')),
        'return_url': 'http://{}{}'.format(host,
                                           reverse('payment:done')),
        'cancel_return': 'http://{}{}'.format(host,
                                              reverse('payment:canceled')),
    }
    form = PayPalPaymentsForm(initial=paypal_dict)
    return render(request,
                  'payment/process.html',
                  {'order': order, 'form': form})


@csrf_exempt
def payment_done(request):
    return render(request, 'payment/done.html')


@csrf_exempt
def payment_canceled(request):
    return render(request, 'payment/canceled.html')

4.修改templates，只需要修staticfiles成為static即可。

(1)shop/templates/shop/base.html

{% load static %}
{% load bootstrap3 %}

    <meta charset="UTF-8">

                        {# If total_items is 2, the output will be 2 items. #}
                        {{ total_items }} item{{ total_items|pluralize }},
                        ${{ cart.get_total_price }}
                    </a>
                {% else %}
                    Your shopping cart is empty.
                {% endif %}
            {% endwith %}
