Question

我收到错误，TemplateDoesNotExist在/ app / index.html或index.html。应用程序（子应用程序）在testapp（父应用程序）中，应用程序的index.html·urls.py·views.py .urls.py的应用程序是

    from django.conf.urls import url
    from . import views


    urlpatterns = [
        url(r'^$', views.index, name='index'),
    ]
views.py of app is 
from django.shortcuts import render


def index(request):
    return render(request, 'app/index.html')

testapp的urls.py是

from django.conf.urls import include, url
from django.contrib import admin
from app.views import index

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

渲染的app中的views.py的参数被改为'index.html'，但是同样的错误发生了。出了什么问题？（写目录的方法是什么？）我该怎么解决这个问题？ Traceback说

Exception Type: TemplateDoesNotExist at /
Exception Value: index.html

Answer 1

HI你的模板应该在（yourapp / templates / index.html）

检查 settings.py 是否具有以下配置

INSTALLED_APPS = ['your_app_name']

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [],
        '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',
                'django.template.context_processors.media'
            ],
        },
    },
]

然后是 view.py

def index(request):
    return render(request, 'index.html')

Answer 2

在设置文件

中

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

意味着Django将查看项目下templates /目录中的模板。

<强> OR

默认情况下可能未定义SETTINGS_PATH。在这种情况下，您需要定义它（在settings.py中）：

import os

SETTINGS_PATH = os.path.dirname(os.path.dirname(__file__))

如果你想这样的话

<强> 应用程序/ index.html的

然后你必须在模板目录中创建app文件夹

试试这个

TEMPLATES = [
{
    'BACKEND': 'django.template.backends.django.DjangoTemplates',
    'DIRS': ['/your/dir/here/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',
        ],
    },
},

TemplateDoesNotExist at /有什么问题？
