我是Django的新手,只是关注Django官方文档,但这是一个问题。
我使用
创建一个新的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
其中大部分是自动创建的,我修改的内容如下:
模板/ hello.html的
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<title>Django test</title>
</head>
<body>
hello world!
</body>
</html>
的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),
]
主/ 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")
它正确运行。
我认为它可能是由模板路径引起的,这里是settings.py,自动生成而不做修改:

您的问题与您的设置有关。你现在有:
TEMPLATE_DIRS = (
os.path.join(BASE_DIR, 'templates'),
)
这是在Django 1.7.x及更低版本中设置模板目录的方法。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',
],
},
},
]
感谢你对你的问题如此彻底。祝你好运!

尝试将模板放在子目录中:
<project>/<app>/templates/<app>/hello.html
和
return render_to_response('<app>/hello.html', locals())
如果您想访问<project>/templates
内的模板,则必须在DIRS
内指定TEMPLATES
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',
],
},
},
]

可能您忘记在INSTALLED_APPS下的settings.py中包含应用程序的名称。这可能对我相信的人有所帮助。

settings.py
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [
os.path.join(BASE_DIR, ''),
],
views.py
返回render(request,“”,{})
例子:
返回render(request,“ pages / template / home.html”,{})

在模板文件夹中更容易的解决方案是创建另一个文件夹,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

我遇到了同样的错误,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 已安装应用程序列表中。以前是这样的:
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
]
现在我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',
]

试试这个方法,在你的 settings.py 中进行更改
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',
],
},
},
]

try {
javax.xml.parsers.DocumentBuilderFactory dbf =
javax.xml.parsers.DocumentBuilderFactory.newInstance();
javax.xml.parsers.DocumentBuilder db = dbf.newDocumentBuilder();
org.w3c.dom.Document document = db.parse(new java.io.File("Students.xml"));
org.w3c.dom.NodeList nodeList = document.getElementsByTagName("student");
for(int x = 0,size = nodeList.getLength(); x < size; x++) {
System.out.println(nodeList.item(x).getAttributes()
.getNamedItem("id").getNodeValue()); // HERE :)
}
}
catch (org.xml.sax.SAXException | java.io.IOException | javax.xml.parsers.ParserConfigurationException ex) {
ex.printStackTrace();
}
你必须导入你的应用主目录的 urls.py 你正在导入视图
像这样改变你的代码
urls.py #in 文件夹 mysite/
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
]
你必须在你的应用主目录中创建一个新文件 命名 urls.py #in 文件夹 main/
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上有网址
