我正在浏览 Django Book。我在第 4 章的中间。我无法呈现我的 current_datetime.html 模板视图。我究竟做错了什么？看起来模板加载器没有找到正确的目录。http://www.djangobook.com/en/2.0/chapter04/

我在我的项目文件夹中创建了我的模板目录，并在目录中创建了 current_datetime.html。

Setting.py
import os.path

TEMPLATE_DIRS = (
    os.path.join(os.path.dirname(__file__), 'templates').replace('\\','/'),
    # I've also tried: # '/Users/macuser/Python_Projects/django_test1/templates',
)

views.py
from django.shortcuts import render_to_response
import datetime

def current_datetime(request):
    now = datetime.datetime.now()
    return render_to_response('current_datetime.html', {'current_date': now})

urls.py
from django.conf.urls import patterns, include, url
from django_test1.views import hello, my_homepage_view, current_datetime, hours_ahead


urlpatterns = patterns('',
    (r'^$', my_homepage_view),
    (r'^hello/$', hello),
    (r'^time/$', current_datetime),
    (r'^time/plus/(\d{1,2})/$', hours_ahead),)

错误：

Template-loader postmortem

Django tried loading these templates, in this order:
Using loader django.template.loaders.filesystem.Loader:
Using loader django.template.loaders.app_directories.Loader:
/Library/Python/2.7/site-packages/django/contrib/auth/templates/current_datetime.html (File does not exist)

你还没有检查 render_to_Response 格式 https://docs.djangoproject.com/en/dev/topics/http/shortcuts/#render-to-response

通过它，您需要将 context_instance=RequestContext(request) 添加到响应中

这是一个愚蠢的错误。我没有创建一个实际的应用程序：python manage.py startapp "appName"。我将“assert False”放在设置文件中，并意识到 django 甚至没有使用我的 settings.py 文件。
