Django DetailView视图

Django的DetailView是一个用于显示单个对象详情的视图。下面是一个使用DetailView来显示单个书籍详情的例子。

1，添加视图

Test/app3/views.py

from django.shortcuts import render

# Create your views here.
from django.views.generic import ListView
from .models import Book

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'

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

urlpatterns = [
    path('books/', BookListView.as_view(), name='book_list'),
    path('books/<int:pk>/', BookDetailView.as_view(), name='book_detail'),
]

3，添加html代码

Test/templates/books/book_detail.html

<!-- 在templates/books/book_detail.html中 -->
<!DOCTYPE html>
<html>
<head>
    <title>{{ book.title }}</title>
</head>
<body>
    <h1>{{ book.title }}</h1>
    <p>Author: {{ book.author }}</p>
    <p>Publication date: {{ book.publication_date }}</p>
</body>
</html>
