在Django中導入模塊（新手）

我對Python和Django都很陌生，我正在努力解決這個問題，這是一件非常簡單的事情。我使用PyCharm作爲我的IDE，並試圖遵循快速入門指南[這裏] [1]。按照教程設置虛擬env。在Django中導入模塊（新手）

該項目是「DjangoProjectApp」和應用程序是「午餐」

隨着文件如下圖所示，在瀏覽器指着http://localhost:8000/admin/我得到的錯誤：

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

但是，如果我註釋掉urls.py中的第二個url路徑，然後它可以工作。什麼是我導入這個模塊的正確方法？謝謝。

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

嘗試用'Lunch.views.index'替換'DjangoProjects.Lunch.views.index'。 – alecxe

謝謝。這確實修復了模塊未發現的錯誤。我認爲我最初添加完全限定名的原因是，沒有它，它會拋出另一個錯誤，指出TemplateDoesNotExist。「索引」絕對是在views.py中定義的，所以你知道它爲什麼找不到它？ – Gadzooks34

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

將該行替換爲：

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

無需指定項目名稱。您應該從應用程序名稱開始。

此外，請確保Lunch位於設置文件中的INSTALLED_APPS。
