Question

我一直在他们的网站上关注官方的Django 1.3教程。当我将自定义应用（民意调查）添加到INSTALLED_APPS中的settings.py列表时，我的问题就出现了：

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    # Uncomment the next line to enable the admin:
    'django.contrib.admin',
    'polls',
    # Uncomment the next line to enable admin documentation:
    # 'django.contrib.admindocs',
)

然而，当我回去查看堆栈跟踪时，我得到了这个：

mod_fcgid: stderr: TemplateSyntaxError: Caught ImportError while rendering: No module named polls

我做错了什么？这是整个堆栈跟踪：

编辑...这是我的sys.path：

我的urls.py：

from django.conf.urls.defaults import patterns, include, url

# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()

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

    # Uncomment the admin/doc line below to enable admin documentation:
    # url(r'^admin/doc/', include('django.contrib.admindocs.urls')),

    # Uncomment the next line to enable the admin:
    url(r'^admin/', include(admin.site.urls)),
)

Answer 1

您的应用是PYTHONPATH吗？您可以通过

在shell中查看它

$ python manage.py shell

并在shell中，使用

进行检查

> import sys
> print sys.path

如果应用未在PYTHONPATH上，您可以使用项目的settings.py添加该应用。

在settings.py：

import os
import sys
PROJECT_ROOT = os.path.dirname(__file__)
sys.path.insert(0, os.path.join(PROJECT_ROOT, "polls"))

如果这不是问题，您是否还可以显示调用模板的urls.py和views.py部分？

Answer 2

遇到同样的问题，解决了，请在settings.py中尝试：

import sys
sys.path.insert(0, "/home/user/django_projects/myproject/")
