Question

我正在使用Django 1.5.1，现在我有一个网页显示我的数据库中的多个条目，但现在我希望每个条目都有一个页面。所以基本上当用户点击标题时，它会将它们带到一个单独的页面，只显示他们点击的条目。

我收到以下错误：

NameError at /
name 'Post' is not defined

以下是我认为与解决此问题相关的每个页面的代码。我还创建了一个post.html页面，这不能是我的错误，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 /中模板/博客/

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>

                <td>{% if post.Returned == True %}
                        Yes
                    {% else %}
                        No

Answer 1

urls.py中有错误需要添加导入Post，导致DetailView使用它作为模型

from blog.models import Post

Answer 2

我会这样做：

在你的views.py中

：

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'

在你的PROJECT中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中：

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()),
)

修改添加了导入

为每个特定条目设置一个页面 - Django
