Question

我目前正在关注一个名为A complete blog engine using Django in 60 minutes and am stuck on page 6的有点可疑的Django教程。所以我有一个名为博客的Django项目，而我内部有一个名为 blogengine 的应用程序。目前，当我尝试加载

时，我收到TemplateDoesNotExist个异常

127.0.0.1:8000/blog/

这是完整的回溯：

Environment:


Request Method: GET
Request URL: http://127.0.0.1:8000/blog/

Django Version: 1.3.1
Python Version: 2.7.2
Installed Applications:
['blogengine',
 'django.contrib.admin',
 'django.contrib.auth',
 'django.contrib.contenttypes',
 'django.contrib.sessions']
Installed Middleware:
('django.middleware.common.CommonMiddleware',
 'django.contrib.sessions.middleware.SessionMiddleware',
 'django.middleware.csrf.CsrfViewMiddleware',
 'django.contrib.auth.middleware.AuthenticationMiddleware',
 'django.contrib.messages.middleware.MessageMiddleware')

Template Loader Error:
Django tried loading these templates, in this order:
Using loader django.template.loaders.filesystem.Loader:
/home/sez/blog/templates/blogengine/post_list.html (File does not exist)
Using loader django.template.loaders.app_directories.Loader:
/usr/local/lib/python2.7/site-packages/django/contrib/admin/templates/blogengine/post_list.html (File does not exist)



Traceback:
File "/usr/local/lib/python2.7/site-packages/django/core/handlers/base.py" in get_response
  111.                         response = callback(request, *callback_args, **callback_kwargs)

Exception Type: TemplateDoesNotExist at /blog/
Exception Value: blogengine/post_list.html

在Template Loader Error中你可以看到Django试图在post_list.html / home / sez / blog / templates / blog /'目录中查找/home/sez/blog/templates/blogengine/' directory. To get this working I have to make Django look in the模板，但我仍然没有完全理解URLconf的工作原理。

以下是我的2 url.py个文件。第一个是我的项目级别url.py

from django.conf.urls.defaults import patterns, include, url
from django.views.generic.simple import direct_to_template
from blog.views import *

from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
        (r'^admin/', include(admin.site.urls)),
        (r'^static/(.*)$',
            'django.views.static.serve',
            {'document_root': '/home/siddhion/blog/static/'}),
        (r'^(?P<template>\w+)$', direct_to_template),
        (r'^$', static_page, {'template':'base'}),
        (r'^blog/', include('blog.blogengine.urls')),
        url(r'^(?P<template>\w+)/$', static_page, name='static_page'),
        )

根据我的理解，行(r'^blog/', include('blog.blogengine.urls')),告诉我将控件重定向到url.py目录中的blogengine文件。这是该文件的代码

from django.conf.urls.defaults import *
from django.views.generic import list_detail
from blog.blogengine.views import Post

urlpatterns = patterns('',
        url(r'^$',
            list_detail.object_list,
            {
                'queryset': Post.objects.all(),
                'template_object_name':'post',
            },
            name='blog_home'
            ),
    )

那么为了让Django找到并呈现urls.py模板，我必须对我的post_list.html文件进行哪些编辑？

Answer 1

假设文件/home/sez/blog/templates/blog/post_list.html存在，您只需要告诉Django在哪里查找它。显然，它会在/home/sez/blog/templates/blogengine/中查找您的模板。您可以通过调整TEMPLATE_DIRS中的settings.py来改变这种情况：

TEMPLATE_DIRS = (
    # Put strings here, like "/home/html/django_templates" or "C:/www/django/templates".
    # Always use forward slashes, even on Windows.
    # Don't forget to use absolute paths, not relative paths.
    '/home/sez/blog/templates/blog',
)

但是，通常的做法是将模板子目录命名为相应的应用程序，因此您可能需要考虑将模板移动到blogengine，Django假定它们现在在这里。

Answer 2

你可以做两件事，要么通过传入template_name参数明确告诉它哪个模板，要么将post_list.html移动到/blog/blog/templates/目录，这是django将寻找的目录（即使您未在TEMPLATE_DIRS）

中指定位置

来自documentation on generic views：

模板名称：

如果未指定template_name，则此视图将使用该模板   ＆lt; app_label＆gt; /＆lt; model_name＆gt; _list.html默认情况下。

如何修复我的Django应用程序的urls.py，以便我停止获取TemplateDoesNotExist异常？
