1，添加模型

Test/app11/models.py?

from django.db import modelsclass Post(models.Model):title = models.CharField(max_length=200)content = models.TextField()pub_date = models.DateTimeField('date published')class Book(models.Model):title = models.CharField(max_length=100)author = models.CharField(max_length=100)publication_date = models.DateField()price = models.DecimalField(max_digits=5, decimal_places=2)def __str__(self):return self.title

?

2，添加視圖函數?

Test/app11/views.py

from django.http import HttpResponse
from app11.models import Book  # 導入你的模型
def updata_book(request):# 假設我們要更新標題為 "My Book Title" 的書籍的作者和價格book = Book.objects.get(title="測試Django 編程")  # 獲取該書籍實例# 更新書籍的作者和價格book.author = "小紅"book.price = 88.88# 保存更改book.save()return HttpResponse("Book updata successfully!")

3，路由地址

Test/app11/urls.py

from django.urls import path
from . import viewsurlpatterns = [path('updata_book/', views.updata_book, name='updata_book'),
]
