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_book2(request):     one_data = Book.objects.filter(author='小强1').delete()      return HttpResponse("author=小强1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 views  urlpatterns = [     path('delete_book2/', views.delete_book2, name='delete_book2'), ]

4，访问页面

http://127.0.0.1:8000/app11/delete_book2/

 可以看到author为小强1的数据都被删除了
