Django DeleteView视图

Django 的 DeleteView 是一个基于类的视图，用于处理对象的删除操作。

1，添加视图函数

Test/app3/views.py

from django.shortcuts import render# Create your views here.
from .models import Bookfrom django.views.generic import ListView
class BookListView(ListView):model = Bookcontext_object_name = 'books'template_name = 'books/book_list.html'paginate_by = 10 # 设置展示页数数据from django.views.generic import DetailView
class BookDetailView(DetailView):model = Bookcontext_object_name = 'book'template_name = 'books/book_detail.html'from django.views.generic.edit import CreateView
class BookCreateView(CreateView):model = Booktemplate_name = 'books/book_form.html'fields = ['title', 'author', 'publication_date']success_url = '/app3/books/' # 重定向至书本列表路由地址from django.urls import reverse_lazy
from django.views.generic.edit import UpdateView
class BookUpdateView(UpdateView):model = Bookfields = ['title', 'author', 'publication_date']template_name = 'books/book_edit.html'success_url = reverse_lazy('book_list')from django.shortcuts import get_object_or_404
from django.urls import reverse
from django.views.generic.edit import DeleteView
class BookDeleteView(DeleteView):model = Booktemplate_name = 'books/book_delete.html'def get_object(self):id_ = self.kwargs.get("id")return get_object_or_404(Book, id=id_)def get_success_url(self):return reverse('book_list')

2，添加路由地址

Test/app3/urls.py

from django.urls import path
from . import viewsfrom .views import BookListView
from .views import BookDetailView
from .views import BookCreateView
from .views import BookUpdateView
from .views import BookDeleteViewurlpatterns = [path('books/', BookListView.as_view(), name='book_list'),path('books/<int:pk>/', BookDetailView.as_view(), name='book_detail'),path('books/new/', BookCreateView.as_view(), name='book_new'),path('books/<int:pk>/edit/', BookUpdateView.as_view(), name='BookUpdateView'),path('books/delete/<int:id>/', BookDeleteView.as_view(), name='book_delete'),
]

3，添加html代码

Test/templates/books/book_delete.html

<!DOCTYPE html>
<html lang="en">
<head><meta charset="UTF-8"><title>Title</title>
</head>
<body><form method="POST">{% csrf_token %}<p>你确定要删除这本书吗？</p><button type="submit">确认删除</button>
</form></body>
</html>
