1，添加模型
Test/app11/models.py
from django.db import models
class 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 views
urlpatterns = [
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
