Question

我对Django非常陌生。我在/处遇到例外TemplateDoesNotExist。我想我的模板DIR有问题。

以下是网址：

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

urlpatterns= [
    url(r'', views.index, name='index'),

]

以下是视图：

从django.shortcuts导入

从django.http导入HttpResponse

def索引（请求）： my_dict = {'insert_me'：“您好，我已经创建了我的第一个动态模板”} 返回render（request，'Twenty3rdMarch / first_app / templates / index.html'，context = my_dict）

这是我的设置：

import os
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
TEMPLATES_DIR=os.path.join(BASE_DIR,'templates')
print(TEMPLATES_DIR)
ALLOWED_HOSTS = []

Please help me out to resolve it.

Answer 1

将Twenty3rdMarch/first_app/templates/index.html更改为index.html。从APP_DIRS引用模板时，您不需要完整路径。

但是我建议您为模板目录正确命名。只需将index.html放在应用程序的模板目录中，可能会导致模板覆盖。您应在应用程序的模板目录中创建具有相同名称的目录。

myapp
  templates
    myapp
      index.html

然后像myapp/index.html

一样引用它

Answer 2

您可以在主项目的文件夹下创建模板文件夹，然后将其更改为settings.py

TEMPLATES = [
{
    'BACKEND': 'django.template.backends.django.DjangoTemplates',
    'DIRS': [os.path.join(BASE_DIR, 'templates')]
    ,
    -----rest of settings ------
}]

模板不会退出异常
