CreateView是Django提供的一个基于类的视图，用于处理创建新对象的操作。它可以帮助你轻松地创建一个表单页面，用户可以通过这个页面创建新的对象。
1，添加视图
Test/app3/views.py
from django.shortcuts import render
# Create your views here.
from .models import Book
from django.views.generic import ListView
class BookListView(ListView):
model = Book
context_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 = Book
context_object_name = 'book'
template_name = 'books/book_detail.html'
from django.views.generic.edit import CreateView
class BookCreateView(CreateView):
model = Book
template_name = 'books/book_form.html'
fields = ['title', 'author', 'publication_date']
2，添加路由地址
Test/app3/urls.py
from django.urls import path
from . import views
from .views import BookListView
from .views import BookDetailView
from .views import BookCreateView
urlpatterns = [
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'),
]
3，添加html代码
Test/templates/books/book_form.html
<!-- 在templates/books/book_form.html中 -->
<!DOCTYPE html>
<html>
<head>
<title>New book</title>
</head>
<body>
<h1>New book</h1>
<form method="post">
{% csrf_token %}
{{ form.as_p }}
<button type="submit">Save</button>
</form>
</body>
</html>
4，访问页面
http://127.0.0.1:8000/app3/books/new/
这个错误表明Django在尝试重定向到新创建的对象的详情页面时找不到要去的URL。
实际上我们的数据已经成功保存下来了
解决保存后页面访问页面问题可参考：
