在Django中导入模块（新手）

我对Python和Django都很陌生，我正在努力解决这个问题，这是一件非常简单的事情。我使用PyCharm作为我的IDE，并试图遵循快速入门指南[这里] [1]。按照教程设置虚拟env。在Django中导入模块（新手）

该项目是“DjangoProjectApp”和应用程序是“午餐”

随着文件如下图所示，在浏览器指着http://localhost:8000/admin/我得到的错误：

ImportError at /admin/ 
No module named 'DjangoProjects.Lunch'

但是，如果我注释掉urls.py中的第二个url路径，然后它可以工作。什么是我导入这个模块的正确方法？谢谢。

urls.py：

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

urlpatterns = patterns('', 
    # Examples: 
    # url(r'^$', 'DjangoProjects.views.home', name='home'), 
    # url(r'^blog/', include('blog.urls')), 

    url(r'^admin/', include(admin.site.urls)), 
    url(r'^lunch/$', 'DjangoProjects.Lunch.views.index') 
)

views.py

from django.shortcuts import render 

# Create your views here. 
from django.shortcuts import render_to_response 


def index(request): 
    return render_to_response('index.html')

的index.html

尝试用'Lunch.views.index'替换'DjangoProjects.Lunch.views.index'。 – alecxe

谢谢。这确实修复了模块未发现的错误。我认为我最初添加完全限定名的原因是，没有它，它会抛出另一个错误，指出TemplateDoesNotExist。 “索引”绝对是在views.py中定义的，所以你知道它为什么找不到它？ – Gadzooks34

检查您的[TEMPLATE_DIRS]（https://docs.djangoproject.com/en/dev/ref/settings/#template-dirs）设置。 – alecxe

将该行替换为：

url(r'^lunch/$', 'Lunch.views.index')

无需指定项目名称。您应该从应用程序名称开始。

此外，请确保Lunch位于设置文件中的INSTALLED_APPS。
