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 delete_book1(request):one_data = Book.objects.get(id=21)one_data.delete()return HttpResponse("id为18的数据删除成功!")
3,添加路由地址
Test/app11/urls.py
from django.urls import path
from . import viewsurlpatterns = [path('delete_book1/', views.delete_book1, name='delete_book1'),
]
4,访问页面
