Question

我正在做一个练习以显示“你好世界！”，但是当我打开网站时，django发出异常。我该怎么做才能解决问题？

例外是：

DemoGuitarProject
  __init__.py
  settings.py
  urls.py
  wsgi.py
apps
  release_news
    __init__.py
    admin.py
    models.py
    tests.py
    urls.py
    views.py
  __init__.py
templates
...

我的项目结构是：

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

from apps import release_news

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^release_news/', include(release_news.urls)), 
]

我在目录DemoGuitarProject中的urls.py是：

from django.conf.urls import include, url

from apps.release_news import views

__author__ = 'Kami Wan'

urlpatterns = [

    url(r'^$', views.index, name='index'),                      
    url(r'^summernote/', include('django_summernote.urls')),  
]

我在应用程序目录release_news中的urls.py是：

# Create your views here.
from django.http import HttpResponse


def index(request):
    return HttpResponse("Hello world ! ")

我的views.py文件是：

import os

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

我的settings.py文件：

<?php

<?php
    $query = $mysqli->query("SELECT * FROM products");
    echo '<select>';
        while($obj = $query->fetch_object()){
            echo '
                <option value"'.$obj->product_name.'">'.$obj->product_name.'</option>
        ';
    }
echo '</select>';
// if product1 is selected, the price is 100 and show in the textbox
//
?>

来自DemoGuitarProject/urls.py的代码

from apps import release_news

读取文件apps/release_news/__init__.py

我猜这个文件是空的。添加到此文件：

from apps.release_news import urls

或更改DemoGuitarProject/urls.py

from apps.release_news import urls as release_news_urls

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^release_news/', include(release_news_urls)), 
]

Django 1.8 AttributeError：模块没有属性'urls'
