我正在研究官方 django 1.7 教程here https://docs.djangoproject.com/en/1.7/intro/tutorial03/。一切都很顺利，除了 django 找不到应用程序的模板。它找到我放在workspace/mysite/templates下但不在workspace/mysite/polls/templates下的模板。
Workspace 是我的主目录中的一个文件夹，我在其中保存所有的 Web 项目。
我的路径是~workspace/mysite/
项目结构是
`workspace
|
mysite
|
db.sqlite3 - manage.py - mysite - mysite_env - polls - templates`
为了简洁起见，我将列出每个文件夹的内容：
- db.sqlite3 - 是一个文件
- manage.py - 是一个文件
- mysite - 是项目文件夹
- mysite_env - 是 virtualenv 文件夹
- polls - 是应用程序文件夹，包含一个文件目录结构，其中包含未选取的模板。打开目录中的结构是 templates/polls/index.html
- templates - 是项目模板目录。它正在被 django 拾取
在我的 mysite/settings.py 中我已指定
`TEMPLATE_DIRS = [os.path.join(BASE_DIR, 'templates')]`
我尝试添加到 polls/templates 文件夹的路径，但这也不起作用。
polls/views.py 索引的设置是：
`def index(request):
latest_question_list = Question.objects.order_by('-pub_date')[:5]
template = loader.get_template('/polls/index.html')
context = RequestContext(request, {
'latest_question_list': latest_question_list,
})
return HttpResponse(template.render(context))`
实际的 polls/templates/polls/index.html 包含：
`{% if latest_question_list % }
<ul>
{% for question in latest_question_list %}
<li><a href="/polls/{{ question.id }}/">{{ question.question_text }}</a>a></li>
{% endfor %}
</ul>
{% else %}
<p>No Polls are available.</p>
{% endif %}`
最后但并非最不重要的一点是， polls/urls.py 包含用于匹配 /polls/ 索引的正则表达式：
`#ex: /polls/
url(r'^$', views.index, name='index'),`
我收到的具体错误是：
`TemplateDoesNotExist at /polls/
/polls/index.html

有人可以帮我解决这个问题吗？我已经尝试找出问题所在太久了。欢迎任何基于当前公认实践的想法。
谢谢。
