每个特定条目都有一个页面 - Django

Question

我正在使用Django 1.5.1，现在我有一个网页显示了多个来自我的数据库的条目，但现在我想为它自己的每个条目都有一个页面。所以基本上当用户点击标题时，它会将它们带到单独的页面，只显示他们点击的条目。

我收到以下错误：

NameError at/
name 'Post' is not defined 

下面是我的，我认为是有关解决这一问题的每个页面的代码。我还创建了一个post.html页面，这样就不会出现我的错误，views.py和urls.py存储在Django的默认目录中，我的post.html和index.html存储在/ mysite/mysite /模板/博客/

的index.html

{% extends 'base.html' %} 
{% block title %} Roadcase WebApp {% endblock %} 
{% block content %} 
    <h1>Roadcase WebApp</h1> 
    <p>Today's Date: {% now "F j, Y" %}</p> 
    <div class="post"> 
     <table class="main"> 
      <tr class="title_head"> 
       <td><a href="">ID</a></td> 
       <td><a href="">Roadcase</a></td> 
       <td><a href="">User</a></td> 
       <td><a href="">Location</a></td> 
       <td><a href="">Date Taken</a></td> 
       <td><a href="">Return Date</a></td> 
       <td><a href="">Returned</a></td> 
      </tr> 
    {% for post in posts %} 
      <tr> 
       <td><a class="n_link" href="/blog/{{post.id}} ">{{post.id}}</a></td> 
       <td>{{post.Roadcase_Number}}</td>

Answer 1

你有urls.py 错误需要增加进口后，引起的DetailView以此为模型

from blog.models import Post 

Answer 2

我会做的是：在你的看法

。潘岳：

from django.shortcuts import render, get_object_or_404 
from django.views.generic import DetailView, ListView 
from blog.models import Post 

class Index(ListView): 
    model = Post 
    template_name = 'blog/index.html' 
    def get_queryset(self) 
     return super(Index, self).get_queryset().filter(published=True).order_by('-id') 

def PostDetailView(DetailView): 
    model = Post 
    template_name = 'blog/post.html' 

项目中的urls.py

：

from django.conf.urls import patterns, include, url 
from django.contrib import admin 

admin.autodiscover() 

urlpatterns = patterns('', 
    url(r'^admin/', include(admin.site.urls)), 
    url(r'^blog/',include("blog.urls")), 

) 

在您的博客应用urls.py：

from blog.views import PostDetailView, Index 

urlpatterns = patterns('', 
    url(r'^$',Index.as_view()), 
    url(r'^post/(?P<slug>[\w-]+)/$',PostDetailView.as_view()), 

    url(r'^post/(?P<pk>\d+)$', PostDetailView.as_view()), 
) 

编辑 增加进口
