可以上传Django媒体，无法检索 [英] Can upload Django media, can't retrieve
问题描述
更新：我缩小了问题。
如果我更改：
MEDIA_URL ='/ media /'
Django提供文件 http://192.168.xxx.xxx/media/media/file.txt
如果我更改：
MEDIA_URL ='/ kittens /'
Django在 http://192.168.xxx.xxx/kittens/file.txt
runserver输出：
urls.py MEDIA_URL：/ media /
urls.py MEDIA_ROOT：
Settings.py MEDIA_ROOT：/ home / user /小猫/
世界上发生了什么？为什么嵌套媒体的url路径？ django.conf.settings.MEDIA_ROOT 是空白的，而 mysite.settings.MEDIA_ROOT 不是？
urls.py
从django.conf导入设置
from django.conf .urls.static import static
urlpatterns = patterns（''，
）+ static（settings.MEDIA_URL，document_root = settings.MEDIA_ROOT）
print'urls .py MEDIA_URL：％s'％（settings.MEDIA_URL）
print'urls.py MEDIA_ROOT：％s'％（settings.MEDIA_ROOT）
settings.py
MEDIA_URL ='/ media /'
MEDIA_ROOT ='/ home / user / kittens /'
打印'Settings.py MEDIA_ROOT：％s'％（MEDIA_ROOT）
在磁盘上

python manage.py runserver
urls.py MEDIA_URL ：/ media /
urls.py MEDIA_ROOT：

验证模型...
您会注意到 urls.py MEDIA_ROOT 是空白。在检查 settings.py 之后，我注意到在配置了 MEDIA_ROOT 之前，正在调用根目录配置。因此，更改订单可以解决问题。
settings.py
＃必须首先指定MEDIA_ROOT，以便urls.py通过django.conf.settings选择它
MEDIA_ROOT ='/ home / user / kittens'
＃然后调用站点root的urls.py
ROOT_URLCONF ='mysite.urls'
我不知道 嵌套的媒体路径，但是改变确实解决了它。也就是说，我可以导航到 http://192.168.xxx.xxx/media/file.txt 。
As the title states, I am lost here because I can upload files to MEDIA_ROOT via the site, but when I attempt to serve them I get a 404 error. The most annoying part is that this worked for ages, now something changed and it's broken.
UPDATE: I've narrowed the problem down.
If I change:
MEDIA_URL = '/media/'
Django serves the file at http://192.168.xxx.xxx/media/media/file.txt
If I change:
MEDIA_URL = '/kittens/'
Django serves the file at http://192.168.xxx.xxx/kittens/file.txt
runserver output:
urls.py MEDIA_URL: /media/
urls.py MEDIA_ROOT:
Settings.py MEDIA_ROOT: /home/user/kittens/
What in the world is going on? Why the "nested" media url path? django.conf.settings.MEDIA_ROOT is blank while mysite.settings.MEDIA_ROOT is not?
urls.py
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = patterns('',
) + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
print 'urls.py MEDIA_URL: %s' % (settings.MEDIA_URL)
print 'urls.py MEDIA_ROOT: %s' % (settings.MEDIA_ROOT)
settings.py
MEDIA_URL = '/media/'
MEDIA_ROOT = '/home/user/kittens/'
print 'Settings.py MEDIA_ROOT: %s' % (MEDIA_ROOT)
On the disk

Out[8]: 'kittens/file.txt'
In [9]: os.path.exists(os.path.join(settings.MEDIA_ROOT, 'file.txt'))
Out[9]: True
The problem was isolated by printing the configuration parameters, i.e.:
settings.py
MEDIA_URL = '/media/'
MEDIA_ROOT = '/home/user/kittens/'
print 'Settings.py MEDIA_ROOT: %s' % (MEDIA_ROOT)
urls.py
from django.conf import settings
from django.conf.urls.static import static
urlpatterns = patterns('',
) + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
print 'urls.py MEDIA_URL: %s' % (settings.MEDIA_URL)
print 'urls.py MEDIA_ROOT: %s' % (settings.MEDIA_ROOT)
python manage.py runserver
urls.py MEDIA_URL: /media/
urls.py MEDIA_ROOT:
Settings.py MEDIA_ROOT: /home/user/kittens
Validating models...
You'll notice the urls.py MEDIA_ROOT is blank. After inspecting settings.py I noticed that the root url configuration was being called before MEDIA_ROOT was configured. Therefore, changing the order fixed the problem.
settings.py
# Must specify MEDIA_ROOT first so urls.py picks it up via django.conf.settings
MEDIA_ROOT = '/home/user/kittens'
# Then call site root's urls.py
ROOT_URLCONF = 'mysite.urls'
I don't know how this caused the "nested" media path, but the change did fix it regardless. That is, I can navigate to http://192.168.xxx.xxx/media/file.txt.
