我是Django新手，按照Django官方文档就可以了，但是这里有个问题。

我用

创建了一个新的 Django 项目

Django 1.8.2 + PyCharm 4.5.1 + Python 3.4.3 + Windows 8.1

  - mysite
     - main
        - migrations
            __init__.py
        __init__.py
        admin.py
        models.py
        tests.py
        views.py
     - mysite
        __init__.py
        settings.py
        urls.py
        wsgi.py
     - templates
        hello.html
     db.sqlite3
     manage.py

大部分都是自动创建的，我修改如下:

模板/hello.html

<!DOCTYPE html>
<html>
<head lang="en">
  <meta charset="UTF-8">
  <title>Django test</title>
</head>
<body>
hello world!
</body>
</html>

我的网站/urls.py

from django.conf.urls import include, url
from django.contrib import admin
from main.views import hello

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^hello/$', hello),
]

主/views.py

from django.shortcuts import render_to_response

def hello(request):
    return render_to_response('hello.html', locals())

然后点击运行并访问localhost:8080，结果如下:

TemplateDoesNotExist at /hello/
hello.html
Request Method: GET
Request URL:    http://127.0.0.1:8000/hello/
Django Version: 1.8.2
Exception Type: TemplateDoesNotExist
Exception Value:    
hello.html
Exception Location: C:\Python34\lib\site-packages\django\template\loader.py in get_template, line 46
Python Executable:  C:\Python34\python.exe
Python Version: 3.4.3
Python Path:    
['C:\\Users\\kant\\Desktop\\code\\PycharmProjects\\mysite',
 'C:\\Users\\kant\\Desktop\\code\\PycharmProjects\\mysite',
 'C:\\Windows\\SYSTEM32\\python34.zip',
 'C:\\Python34\\DLLs',
 'C:\\Python34\\lib',
 'C:\\Python34',
 'C:\\Python34\\lib\\site-packages']

如果我将 views.py 更改为

from django.http import HttpResponse

def hello(request):
    return HttpResponse("hello world")

它运行正常。

我觉得可能是模板路径的问题，这里是settings.py，没有修改自动生成:

"""

最佳答案

您的问题出在您的设置上。您目前拥有:

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

这是在 Django 1.7.x 及以下版本中设置模板目录的方式。在 Django 1.8.x 中，将您的 TEMPLATES [] 更改为如下所示:

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [
            os.path.join(BASE_DIR, 'templates'),
        ],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

感谢您如此详尽地回答您的问题。祝你好运!
