TemplateDoesNotExist 处的错误 /

【中文标题】TemplateDoesNotExist 处的错误 /

【英文标题】：Error at TemplateDoesNotExist at /

【发布时间】：2017-03-03 17:16:56

【问题描述】：

我正在使用 django 1.10.2 版本，我收到一个错误，显示 TemplateDoesNotExist at /

我不知道为什么会这样，我尝试修复它：

“目录”： ['C:\Users\rahul\django-tuts\cms\blog\templates\blog\post'],

或

'DIRS': [os.path.join(os.path.dirname(file), '..//', '模板').replace('\', '/')],

仍然遇到同样的错误。

以下是我的文件内容：

"""cms URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/1.10/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  url(r'^$', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  url(r'^$', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.conf.urls import url, include
    2. Add a URL to urlpatterns:  url(r'^blog/', include('blog.urls'))

from django.conf.urls import url, include

    url(r'^admin/', admin.site.urls),
    url(r'^$', include('blog.urls', namespace='blog', app_name='blog')),

views.py

from django.shortcuts import render
from .models import Post
# Create your views here.

def list_of_post(request):
    post = Post.objects.all()
    template = 'blog/post/list_of_post.html'
    context = 'post': post
    return render(request, template, context)

【问题讨论】：

请展示您的项目布局，包括blog/post/list_of_post.html模板的位置。

顺便说一句，您应该从包含您的博客网址的正则表达式中删除美元：url(r'^', include('blog.urls', namespace='blog', app_name='blog')),

【参考方案1】：

我认为你应该考虑你的项目根：

考虑到您的templates/blog 文件夹，应该是这样的：

TEMPLATES = [
    
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': ['templates/blog'],
        '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',
            ],
        ,
    ,
]

然后要使用模板，您只需指定templates/blog 文件夹中的相对路径：

from django.shortcuts import render
from .models import Post
# Create your views here.

def list_of_post(request):
    post = Post.objects.all()
    template = 'post/list_of_post.html'
    context = 'post': post
    return render(request, template, context)

它应该可以工作。
