django 中的 TemplateDoesNotExist

Question

你好，我是学习 django 的新手，我遇到了这个 TemplateDoesNotExist 错误

我正在运行 Windows 8

当我检查错误页面时，值 TEMPLATE_DIRS 是 ['C:/ENVS/boardgames/boardgames/templates'] 并且这条路径是完全正确的。从那里我需要加载“helloworld.html”作为模板

我在 Views.py 中这样做

from django.views.generic.base import TemplateView
from django.http import HttpResponse


class HelloWorldView(TemplateView):
    template_name='helloworld.html'

Settings.py

"""
Django settings for boardgames project.

Generated by 'django-admin startproject' using Django 1.8.

"""

# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
import os

BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

USE_TZ = True


# Static files (CSS, JavaScript, Images)


STATIC_URL = '/static/'
TEMPLATE_DIRS = [os.path.join(BASE_DIR, 'templates').replace('\\','/')]

和Url.py

from django.conf.urls import include, url
from django.contrib import admin

from .views import HelloWorldView
urlpatterns = [
    # Examples:
     url(r'^$', HelloWorldView.as_view(), name='home'),
    # url(r'^blog/', include('blog.urls')),

    url(r'^admin/', include(admin.site.urls)),
]

当我查看教程时，似乎很容易。当我将模板文件夹复制到 django\contrib 目录时，它实际上可以工作。我真的很痛苦。但我希望它正确完成并从我希望它们所在的目录加载模板

我做错了什么？请帮忙

TEMPLATE_DIRS 在 django 1.8 中已弃用。您应该改用TEMPLATES 设置。您的 settings.py 文件中已经有了这个变量，所以像这样修改它：

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, 'templates').replace('\\','/')],
        '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',
            ],
        },
    },
]
