22717	FileField.url returns a wrong URL	david.fischer.ch@…	nobody	"
models.py:
{{{
...
class Media(models.Model):
    ....
    file = models.FileField(upload_to=storages.upload_to, storage=storages.media_storage)
    ...
}}}

storages.py:
{{{
...
def upload_to(instance, filename):
    return '%s/%s' % (instance.pk, filename)

media_storage = FileSystemStorage(location='/test/media', base_url='/test/media')
}}}

Django shell:
{{{
...
>>> m = Media.objects.get(pk=27)
>>> m.file.storage.base_url
'/test/media'
>>> m.file.name
'salut.txt'
>>> m.file.url
'/test/salut.txt'
}}}

Expected -> '/test/media/salut.txt'

Investigating:
{{{
>>> from django.utils.six.moves.urllib.parse import urljoin
>>> urljoin('/test/media', 'salut.txt')
'/test/salut.txt'
}}}"	Bug	closed	File uploads/storage	dev	Normal	fixed	storage,filefield,url		Ready for checkin	1	0	0	0	1	0
