【问题描述】：

我对 Django 很陌生。我在 / 处遇到异常 TemplateDoesNotExist。 我猜我的模板 DIR 有问题。

这是网址：

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

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

这是视图：

from django.shortcuts import render
from django.http import HttpResponse


def index(request):
    my_dict='insert_me':"Hello I have created my first dynamic Template"
    return 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 = []

请帮我解决它。

【参考方案1】：

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

不过，我建议您正确命名模板目录。简单地将index.html 放在应用程序的模板目录中可能会导致模板覆盖。您应该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

更多信息，请阅读this doc。

【参考方案2】：

您可以在主项目的文件夹下创建模板文件夹，并将此更改更改为您的 settings.py

TEMPLATES = [

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