索尔缩略图不好的网址 [英] Sorl-thumbnail bad url's
问题描述
我按照说明设置了sorl-thumbnail，但是当我尝试在我的应用程序中使用模板标签时，没有任何图像出现。
I setup sorl-thumbnail according to instructions, but none of the images are appearing when I try to use the templatetags in my app.
看起来，不正确，但不清楚需要什么额外的配置。
It appears that the url's are not valid, but it's not clear what additional configuration is needed.
生成像这样的图像：
<img src="cache/e5/25/e5253a328b9130ecd7d820893f44b0e6.jpg" width="100" height="100">
缓存/ ...如何解决图像请求？这些请求是相对于我的应用程序，而不是sorl-thumbnail：
How does "cache/..." get resolved to a request for an image? These requests are relative to my application, not to sorl-thumbnail:
[31/May/2011 07:13:05] "GET /myapp/cache/e5/25/cache/e5/25/cache/00/73/0073095ee4b968b45386ef3fec4f389c.jpg HTTP/1.1" 200 1004
以下是settings.py中的相关行：
Here are the relevant lines in settings.py:
INSTALLED_APPS = (
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'django.contrib.messages',
# Uncomment the next line to enable the admin:
'django.contrib.admin',
'mysite.myapp',
'sorl.thumbnail',
)
CACHES = {
# 'default': {
# 'BACKEND': 'django.core.cache.backends.db.DatabaseCache',
# 'LOCATION': 'cache',
# }
'default': {
'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
'LOCATION': '127.0.0.1:11211',
}
}
# URL that handles the media served from MEDIA_ROOT. Make sure to use a
# trailing slash if there is a path component (optional in other cases).
# Examples: "http://media.lawrence.com", "http://example.com/media/"
MEDIA_URL = ''
# URL prefix for admin media -- CSS, JavaScript and images. Make sure to use a
# trailing slash.
# Examples: "http://foo.com/media/", "/media/".
ADMIN_MEDIA_PREFIX = '/media/'
这是我的模板中的代码： p>
This is the code in my template:
{% thumbnail auction.item.image "100x100" crop="center" as im %}
<img src="{{ im.url }}" width="{{ im.width }}" height="{{ im.height }}">
{% endthumbnail %}
图像肯定会上传（我查看了指定的目录在upload_to中），当我使用文件系统缓存时，它们被存储在相对于我的应用程序的目录缓存中。我更改了使用memcache来查看是否有帮助。
The image is definitely getting uploaded (I checked the directory specified in upload_to), and when I was using the filesystem cache they were getting stored in the directory cache/ relative to my app. I changed it to use memcache to see if that would help.
推荐答案
您需要正确配置MEDIA_URL。 ImageFile的url属性基本上只是一个来自底层存储后端对于开箱即用的Django，以生成FileField的URL。
You need to configure MEDIA_URL correctly. The "url" attribute of an ImageFile is basically just a pass-through from the underlying storage backend. For out-of-the-box Django, the upload_to path is appended to MEDIA_URL to generate the URL for a FileField.
你有什么：''+'cache / e5 / 25 / e5253a328b9130ecd7d820893f44b0e6.jpg'
你想要的：'/ media /'+'cache / e5 / 25 / e5253a328b9130ecd7d820893f44b0e6.jpg'
What you have: '' + 'cache/e5/25/e5253a328b9130ecd7d820893f44b0e6.jpg'
What you want: '/media/' + 'cache/e5/25/e5253a328b9130ecd7d820893f44b0e6.jpg'
注意：你需要确保MEDIA_URL被别名/映射到Django将您的文件上传到（MEDIA_ROOT）的任何目录。
Note: you would need to make sure that MEDIA_URL is aliased/mapped to whatever directory Django is uploading your files to (MEDIA_ROOT).
