Atualmente, estou usando este código em um s3utils
módulo separado :
from django.core.exceptions import SuspiciousOperation
from django.utils.encoding import force_unicode
from storages.backends.s3boto import S3BotoStorage
def safe_join(base, *paths):
"""
A version of django.utils._os.safe_join for S3 paths.
Joins one or more path components to the base path component intelligently.
Returns a normalized version of the final path.
The final path must be located inside of the base path component (otherwise
a ValueError is raised).
Paths outside the base path indicate a possible security sensitive operation.
"""
from urlparse import urljoin
base_path = force_unicode(base)
paths = map(lambda p: force_unicode(p), paths)
final_path = urljoin(base_path + ("/" if not base_path.endswith("/") else ""), *paths)
# Ensure final_path starts with base_path and that the next character after
# the final path is '/' (or nothing, in which case final_path must be
# equal to base_path).
base_path_len = len(base_path) - 1
if not final_path.startswith(base_path) \
or final_path[base_path_len:base_path_len + 1] not in ('', '/'):
raise ValueError('the joined path is located outside of the base path'
' component')
return final_path
class StaticRootS3BotoStorage(S3BotoStorage):
def __init__(self, *args, **kwargs):
super(StaticRootS3BotoStorage, self).__init__(*args, **kwargs)
self.location = kwargs.get('location', '')
self.location = 'static/' + self.location.lstrip('/')
def _normalize_name(self, name):
try:
return safe_join(self.location, name).lstrip('/')
except ValueError:
raise SuspiciousOperation("Attempted access to '%s' denied." % name)
class MediaRootS3BotoStorage(S3BotoStorage):
def __init__(self, *args, **kwargs):
super(MediaRootS3BotoStorage, self).__init__(*args, **kwargs)
self.location = kwargs.get('location', '')
self.location = 'media/' + self.location.lstrip('/')
def _normalize_name(self, name):
try:
return safe_join(self.location, name).lstrip('/')
except ValueError:
raise SuspiciousOperation("Attempted access to '%s' denied." % name)
Então, no meu módulo de configurações:
DEFAULT_FILE_STORAGE = 'myproyect.s3utils.MediaRootS3BotoStorage'
STATICFILES_STORAGE = 'myproyect.s3utils.StaticRootS3BotoStorage'
Eu tive que redefinir o _normalize_name()
método privado para usar uma versão "fixa" da safe_join()
função, já que o código original está me dandoSuspiciousOperation
exceções para caminhos legais.
Estou postando isso para consideração, se alguém puder dar uma resposta melhor ou melhorar esta, será muito bem-vindo.
