Django 更新数据 save()方法

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，添加视图函数 

Test/app11/views.py

from django.http import HttpResponse
from app11.models import Book  # 导入你的模型
def updata_book(request):# 假设我们要更新标题为 "My Book Title" 的书籍的作者和价格book = Book.objects.get(title="测试Django 编程")  # 获取该书籍实例# 更新书籍的作者和价格book.author = "小红"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'),
]
