python - 模板不存在 at/polls/index.html

Question

我正在做一个关于 django 项目的教程。 实际上现在是凌晨 4.51，我想让它正常工作。

我的 urls.py 文件:

from django.conf.urls import patterns, include, url

from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    (r'^polls/$', 'polls.views.index'),
)

我的views.py文件:

from django.shortcuts import render

# Create your views here.
from django.shortcuts import render_to_response


def index(request):
    return render_to_response('index.html')

在文件夹模板中，我有index.html 文件。 它向我展示了相同的 TemplateDoesNotExist 错误，所以我做了一些研究并 I found this question 所以我在我的settings.py中添加了这段代码:

import os.path
SITE_ROOT = os.path.dirname(os.path.realpath(__file__))
TEMPLATE_DIRS = (
    os.path.join(SITE_ROOT, 'templates/'),
)

那么如何让它发挥作用呢？

这是回溯:

    Environment:

Template Loader Error:
Django tried loading these templates, in this order:
Using loader django.template.loaders.filesystem.Loader:

Exception Type: TemplateDoesNotExist at /polls/

Answer 1

改变

import os.path
SITE_ROOT = os.path.dirname(os.path.realpath(__file__))

至

import os
SITE_ROOT = os.path.dirname(os.path.dirname(__file__))

如果您查看回溯，Python 正在您的应用程序文件夹中查找模板文件夹，我认为它将与 settings.py 位于同一文件夹中。

另一种方法是将模板文件夹复制到 MyDjangoAPP 文件夹中。
