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//', 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

    


    
New book
    
        {% csrf_token %}
        {{ form.as_p }}
        Save
    

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：
