Sorl-缩略图错误网址
我根据说明设置了 sorl-thumbnail,但是当我尝试在应用程序中使用模板标签时,没有任何图像出现。
该 URL 似乎无效,但尚不清楚需要哪些额外配置。
生成这样的图像:
<img src="cache/e5/25/e5253a328b9130ecd7d820893f44b0e6.jpg" width="100" height="100">
“cache/...”如何解析为图像请求?这些请求与我的应用程序相关,而不是 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:
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/'
这是我模板中的代码:
{% thumbnail auction.item.image "100x100" crop="center" as im %}
<img src="{{ im.url }}" width="{{ im.width }}" height="{{ im.height }}">
{% endthumbnail %}
图像肯定正在上传(我检查了 upload_to 中指定的目录),并且何时我正在使用文件系统缓存,它们存储在相对于我的应用程序的目录 cache/ 中。我将其更改为使用内存缓存,看看是否有帮助。
I setup sorl-thumbnail according to instructions, but none of the images are appearing when I try to use the templatetags in my app.
It appears that the url's are not valid, but it's not clear what additional configuration is needed.
A image like like this is generated:
<img src="cache/e5/25/e5253a328b9130ecd7d820893f44b0e6.jpg" width="100" height="100">
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
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/'
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 %}
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.

您需要正确配置MEDIA_URL。 ImageFile 的 "url" 属性 基本上只是来自底层存储后端。对于开箱即用的 Django, upload_to 路径附加到 MEDIA_URL 以生成 FileField 的 URL。
你有什么:'' + 'cache/e5/25/e5253a328b9130ecd7d820893f44b0e6.jpg'
你想要什么: '/media/' + 'cache/e5/25/e5253a328b9130ecd7d820893f44b0e6.jpg'
注意:你需要确保 MEDIA_URL 是别名/映射到 Django 将文件上传到的任何目录 (MEDIA_ROOT)。

请参阅以下默认 Django 存储后端源的链接。
https://code.djangoproject .com/browser/django/tags/releases/1.3/django/core/files/storage.py#L154
https://code.djangoproject .com/browser/django/tags/releases/1.3/django/core/files/storage.py#L240
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.
What you have: '' + 'cache/e5/25/e5253a328b9130ecd7d820893f44b0e6.jpg'
What you want: '/media/' + 'cache/e5/25/e5253a328b9130ecd7d820893f44b0e6.jpg'
Note: you would need to make sure that MEDIA_URL is aliased/mapped to whatever directory Django is uploading your files to (MEDIA_ROOT).
