【问题描述】：

按照在线教程进行操作时，我完全按照说明进行操作，但出现下面列出的错误。我在访问管理员时可以看到模型已经创建，但是当我访问http://127.0.0.1:8000/friends/ 时出现以下错误。我必须创建一个朋友/urls.py 文件并在那里定义一些东西吗？谢谢你的帮助，我很抱歉我是个菜鸟！

ImportError at /friends/
No module named urls

我的项目结构如下：

atmos_v4/
    atmos_v4/
       init__.py
       settings.py
       urls.py
       wsgi.py
    band/
        __init__.py
        admin.py
        models.py
        urls.py
        views.py
    db.sqlite3
    friend
        __init__.py
        admin.py
        models.py
        views.py
    manage.py
    static/
         css/
             ...
         img/
             ...
         js/
             ...
         media/
             ...
    templates/
             band/
                 band.html

我的 urls.py 文件：

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

urlpatterns = patterns('',
    url(r'^$', TemplateView.as_view(template_name="index.html")),
    url(r'^admin/', include(admin.site.urls)),
    .
    .
    .
    (r'^friends/$', 'friend.views.FriendsAll'),

)

我的朋友/models.py 文件：

from django.db import models
import datetime

class Friend(models.Model):
    name = models.CharField(max_length=100, unique=True)
    date_added = models.DateTimeField(default=datetime.datetime.now())
    date_founded = models.DateTimeField(null=True, blank=True)
    image = models.CharField(max_length=1000, null=True, blank=True)

    def __unicode__(self):
        return self.name

我的朋友/admin.py 文件：

from friend.models import Friend
from django.contrib import admin

class FriendAdmin(admin.ModelAdmin):
    list_display = ('name', )
    search_fields = ['title']

admin.site.register(Friend, FriendAdmin)

我的朋友/views.py 文件：

from django.shortcuts import render_to_response
from django.template import RequestContext

def FriendsAll(request):
    friend = Friend.objects.all().order_by('name')
    context = 'friends':friends
    return render_to_response('index.html', context, context_instance=RequestContext(request))

我的 index.html 文件的一部分：

<div class="friendList">
        <ul>
            <li> friend </li>

        </ul>
    </div><!-- end friend list--> 

settings.py 文件：

【问题讨论】：

索引渲染了吗？

您是否在已安装的应用中添加了好友？

@cdvv7788 不，索引未呈现，我确实在已安装的应用程序中添加了朋友

如果locahost:8000 没有渲染，您的项目设置有问题。你是用 startproject 创建的吗？

ImportError 来自哪个文件？

【参考方案1】：

在 settings.py 中将 Friends 模块添加到 INSTALLED_APPS
