django 错误 TemplateDoesNotExist

Question

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：

templates/hello.html

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

mysite/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),
]

main/views.py

from django.shortcuts import render_to_response

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

并单击运行并访问 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")

运行正确。

我觉得可能是模板路径问题，这里是settings.py，没有修改自动生成：

Answer 1

尝试将模板放入子目录中：

 <project>/<app>/templates/<app>/hello.html

和

return render_to_response('<app>/hello.html', locals())

如果要访问 <project>/templates 中的模板，则必须在 TEMPLATES

中指定 DIRS

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',
            ],
        },
    },
]

Answer 2

您的问题出在您的设置上。您目前拥有：

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

这就是您在 Django 1.7.x 及更低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！

Answer 3

您可能忘记在 INSTALLED_APPS 下的 settings.py 中包含应用程序的名称。这可能会帮助我相信的人。

Answer 4

settings.py

TEMPLATES = [     
    {   
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [
            os.path.join(BASE_DIR, ''),
        ],

views.py
return 渲染（请求，“”，{}）
示例：
return 渲染（请求，"pages/template/home.html"，{}）

Answer 5

在模板文件夹中更简单的解决方案创建另一个文件夹并将其命名为您的应用程序名称，这样您的文件树应该如下所示：

 - 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
   -mysite
       hello.html
 db.sqlite3
 manage.py

Answer 6

我有同样的错误，但不知道是什么原因造成的。我意识到我没有将我的应用程序添加到 Django 安装的应用程序列表中。以前它是：

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
]

现在我已经添加了我的应用程序，它看起来像

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'main',
]

Answer 7

试试这个方法，改变你的 settings.py

    TEMPLATES = [
{
    'BACKEND': 'django.template.backends.django.DjangoTemplates',
    'DIRS': [
        os.path.join( BASE_DIR ,'projectname/templates/')
        ],`enter code here`
    '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',
        ],
    },
},

]

Answer 8

mysite/urls.py

from django.conf.urls import include, url
from django.contrib import admin
from main.views import hello # this is the error

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

您必须导入 urls.py 您的应用程序主你正在导入视图

像这样更改您的代码

urls.py #in 文件夹 mysite/

from django.conf.urls import path, include, url
from django.contrib import admin
from . import views ##add this line

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url('main/', include(main.urls), name='main'), ## add this line
]

您必须在您的应用程序主目录中创建一个新文件命名的 urls.py #in 文件夹 main/

from django.urls.conf import path
from . import views

app_name = 'main'

urlpatterns = [
    path('', views.hello, name="hello"),
]

您在主文件夹中创建的最后一个文件告诉你的项目在主应用程序上有 urls

django 错误 TemplateDoesNotExist

django error TemplateDoesNotExist

python

django

django-templates
