Django图书商城系统实战开发-实现商品管理

# 假设我们已经有了一个Django模型Book
from django.shortcuts import render
from django.http import HttpResponseRedirect
from .models import Book
 
def manage_books(request):
    # 获取所有图书
    books = Book.objects.all()
    return render(request, 'books.html', {'books': books})
 
def add_book(request):
    # 添加新图书的逻辑
    if request.method == 'POST':
        title = request.POST['title']
        author = request.POST['author']
        price = request.POST['price']
        new_book = Book.objects.create(title=title, author=author, price=price)
        # 重定向到图书列表页面
        return HttpResponseRedirect('/books/')
    return render(request, 'add_book.html')
 
def edit_book(request, book_id):
    # 编辑图书的逻辑
    if request.method == 'POST':
        title = request.POST['title']
        author = request.POST['author']
        price = request.POST['price']
        book = Book.objects.get(id=book_id)
        book.title = title
        book.author = author
        book.price = price
        book.save()
        # 重定向到图书列表页面
        return HttpResponseRedirect('/books/')
    book = Book.objects.get(id=book_id)
    return render(request, 'edit_book.html', {'book': book})
 
def delete_book(request, book_id):
    # 删除图书的逻辑
    book = Book.objects.get(id=book_id)
    book.delete()
    # 重定向到图书列表页面
    return HttpResponseRedirect('/books/')

这个代码实例提供了创建、编辑和删除图书的基础视图函数。它使用了Django的ORM来与数据库交互，并通过POST请求处理表单数据。这些函数应该与相应的模板和URL配置一起工作，以构建一个完整的图书商城系统。
