I'm in the middle of a migration, including moving from
FileSystemStorage to blobs, and I used the following method to deal
with one FSS field. It is exceedingly simple:
from cStringIO import StringIO
from Products.Archetypes.Storage import AttributeStorage
from iw.fss.FileSystemStorage import FileSystemStorage
attr_storage = AttributeStorage()
fss_storage = FileSystemStorage()
def migratePublication(pub):
field = pub.Schema()['Attachmentfile']
content = StringIO(str(fss_storage.get('Attachmentfile', pub)))
fss_storage.unset('Attachmentfile', pub)
field.set(pub, content)
The method is called for each and every publication item, and it's
really very simple. I didn't have to auto-detect what fields were
affected though, not sure how you'd do that if that was needed. In my
case 'Attachmentfile' is the field name to be migrated. I also
completely ignore any mime-type; it depends on your use-case if you
want to detect / migrate that information.
Hope this is of some use to someone.
