Django找不到应用程序模板 [英] Django Can't Find App Templates

问题描述

我正在通过官方的django 1.7教程发现 here 。一切顺利，除了django找不到应用程序的模板。它找到我放在workspace / mysite / templates下的模板，但不在workspace / mysite / polls / templates下。

工作区是我的主目录中的一个文件夹我的路径是〜workspace / mysite /

和项目结构是

 `workspace 
 | 
 mysite 
 | 
 db.sqlite3  -  manage.py  -  mysite  -  mysite_env  -  polls  -  templates` 
  

I只需列出每个文件夹的内容，以简化：

• 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，其中的模板未被拾取。打开目录中的结构是templates / polls / index.html


• templates - 是项目模板目录。在我指定的mysite / settings.py中，它正在被django

拾取

 `TEMPLATE_DIRS = [os.path.join（BASE_DIR，'templates'）]`
  

我尝试添加一个路径到polls / templates文件夹，但这也不起作用。

polls / views。索引的py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））`
  

polls / templates / polls / index.html包含：

 `{％if latest_question_list％} 
< ul> 
 {％new_question_list％}中的问题
< li>< a href =/ polls / {{question.id}} /> {{question.question_text}}< /一个>一种与GT;< /锂> 
 {％endfor％} 
< / ul> 
 {％else％} 
< p>没有可用的投票。< / p> 
 {％endif％}`
  

最后但并非最不重要的是，polls / urls.py包含用于/ polls /的匹配索引的正则表达式：

 `#ex：/ polls / 
 url（r' ^ $'，views.index，name ='index'），`
  

得到的是：

 `TemplateDoesNotExist at / polls /

有人可以帮我吗？我一直在试图找出错误的方式太久了。欢迎任何基于目前公认的做法的想法。

谢谢。

解决方案

删除第一个 / 从模板名称斜杠。它应该是：

  template = loader.get_template（'polls / index.html'）
  

I'm working through the official django 1.7 tutorial found here. Everything is going smoothly except django can't find the templates for apps. It finds templates that I put under workspace/mysite/templates but not under workspace/mysite/polls/templates.

workspace is a folder I have in my home directory where I'm keeping all my web projects.

My path is ~workspace/mysite/

and the project structure is

`workspace
  |
  mysite
     |
     db.sqlite3 - manage.py - mysite - mysite_env - polls - templates`

I'll just list the contents of each folder for brevity:

• db.sqlite3 - is a file
• manage.py - is a file
• mysite - is the project folder
• mysite_env - is the virtualenv folder
• polls - is the app folder and contains a file directory structure with the templates that aren't being picked up. The structure within the open directory is templates/polls/index.html
• templates - is the project template dir. It is being picked up by django

in my mysite/settings.py I have specified

`TEMPLATE_DIRS = [os.path.join(BASE_DIR, 'templates')]`

I tried adding a path to the polls/templates folder, but that didn't work either.

polls/views.py settings for index is:

`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))`

the actual polls/templates/polls/index.html contains:

`{% 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 %}`

and last but not least, polls/urls.py contains this regex for matching index for /polls/:

`#ex: /polls/
    url(r'^$', views.index, name='index'),`

The specific error I'm getting is:

`TemplateDoesNotExist at /polls/

The traceback it's giving is:

Can someone please help me with this? I've been trying to figure out what's wrong for way too long now. Any ideas based on currently accepted practices are welcome.

Thank you.

解决方案

Remove the first / slash from the template name. It should be:

template = loader.get_template('polls/index.html')
