Comment (by [EMAIL PROTECTED]):
I'd like to propose adding a few methods that we use a lot at KI. We have
a similar setup (generic filesystem that can be local or remote) and I've
found that they are very helpful. I can add a patch once Gulopine updates
his patches for the newest svn if people are interested. Here are some of
the functions we use for this kind of thing (in production) that we've
found helpful:
{{{
def modtime(self, key):
return os.path.getmtime(os.path.join(self.root, key))
def delete_by_prefix(self, prefix):
for root, dirs, files in os.walk(self.root, topdown=False):
for name in files:
if name.startswith(prefix):
os.unlink(os.path.join(root, name))
def list_dir(self, prefix=None):
files = os.listdir(self.root)
if prefix is not None:
return [x for x in files if x.startswith(prefix)]
return files
def copy(self, old_key, new_key):
import shutil
shutil.copy(
os.path.join(self.root, old_key),
os.path.join(self.root, new_key)
)
}}}
I'll comment the s3 implementations in that ticket. delete_by_prefix is
especially useful since we generate out thumbnails of images (our naming
is model_id_field.ext so thumbnails might be model_id_field_399x233.ext).
We generally use the local FS for testing and deployments use the S3
backend.
