我已经设置了 django-sorl，我真的认为我忽略了一些简单的东西。我不断收到以下错误（TEMPLATE_DEBUG = True 和 THUMBNAIL_DEBUG = True）
请求方法：GET 请求地址： http://localhost:8000/events/edit/1
Django 版本：1.2.4 异常类型：TemplateSyntaxError 异常值：
渲染时捕获 IOError：（2，'没有这样的文件或目录'）
异常位置：/usr/lib/python2.6/site-packages/django/core/files/storage.py 在 _open，第 137 行
Python 可执行文件：/usr/bin/python Python 版本：2.6.4
我正在运行 redis 服务器设置...我的 sorl 配置是：
settings.py -snip-：
TEMPLATE_DEBUG = DEBUG
THUMBNAIL_DEBUG = DEBUG
THUMBNAIL_KVSTORE = 'sorl.thumbnail.kvstores.redis_kvstore.KVStore'
INSTALLED_APPS = (
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'django.contrib.messages',
'sorl.thumbnail',
)
models.py -snip-：
from sorl.thumbnail import ImageField
...
path = ImageField(
_('Image'),
upload_to='event/%Y/%m/%d/%H',
)
...
模板.html -snip-：
{% load thumbnail %}
...
{% thumbnail image "200x100" as im %}
<img src="{{ im.url }}" alt="{{ im.name }}"/>
{% endthumbnail %}
...
我想我已经接近了，因为文件是在缓存文件夹中按需创建的
sh> find static/cache/ -type f
static/cache/db/ac/dbac605942d9651eb25f16cf05f5e672.jpg
static/cache/82/bc/82bcdd2ab079187c6b6110cb0e0c1505.jpg
static/cache/07/77/077784411739d4f8b1758255783388ec.jpg
当我打开这些文件时；它们是我按需请求的图像。尝试打开图像以显示它时似乎正在轰炸。需要注意的另一件事是，如果我只使用以下语法显示图像，它将可以正常工作（没有 sorl）：
工作template.html（没有sorl - 因此......没有缩略图）-snip-：
<img src="{{ MEDIA_URL}}{{ image.path }}" alt="{{ image.name }}"/>
关键是；我确实需要为要显示的图像添加 {{ MEDIA_URL }} 标签的前缀（我不确定这是否是我在使用 sorl 时遇到的错误的一个因素，或者只是一个红鲱鱼。
现在是原始错误的一些最终花絮（它们来自正在生成的 TemplateSyntaxError 页面 - 最后 5 个）。

我没有成功地用谷歌搜索这个错误；我希望我的问题只是一个快速的问题，因为除了模板显示之外一切正常。
