我目前正在关注一个有点问题的 Django 教程，名为A complete blog engine using Django in 60 minutes 并停留在第 6 页。所以我有一个名为blog的 Django 项目和一个名为blogengine的应用程序。目前我在TemplateDoesNotExist尝试加载时遇到异常

127.0.0.1:8000/blog/

这是完整的追溯：

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)

File "/usr/local/lib/python2.7/site-packages/django/template/loader.py" in find_template
  138.     raise TemplateDoesNotExist(name)

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

在Template Loader Error您可以看到 Django 尝试post_list.html在/home/sez/blog/templates/blogengine/' directory. To get this working I have to make Django look in the/home/sez/blog/templates/blog/' 目录中查找模板，但我仍然不完全了解其URLconf工作原理。

以下是我的2个url.py文件。首先是我的项目级别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'),
        )

据我了解，该行(r'^blog/', include('blog.blogengine.urls')),告诉将控制权重定向到url.py我blogengine目录中的文件。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'
            ),
    )

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

假设文件/home/sez/blog/templates/blog/post_list.html存在，你只需要告诉 Django 在哪里寻找它。显然，它会在/home/sez/blog/templates/blogengine/. TEMPLATE_DIRS您可以通过调整settings.py：

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，将模板子目录命名为它们对应的应用程序是一种常见的做法，因此您可能需要考虑将模板移动到blogengineDjango 假设它们目前所在的位置。

您可以做两件事，要么通过传入参数明确告诉它哪个模板template_name，要么移动post_list.html到/blog/blog/templates/目录，这是 django 将查找它的位置（即使您没有在 中指定位置TEMPLATE_DIRS）

从有关通用视图的文档中：

模板名称：

如果未指定 template_name，此视图将默认使用模板 <app_label>/<model_name>_list.html。
