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 delete_book3(request):Book.objects.all().delete()return HttpResponse("删除所有数据")
3，添加路由应用
Test/app11/urls.py
from django.urls import path
from . import viewsurlpatterns = [path('delete_book3/', views.delete_book3, name='delete_book3'),
]
4，访问页面
http://127.0.0.1:8000/app11/delete_book3/
可以看到所有的数据都被删除了
