Why not implement your own create and update form with SQLFORM and once the
record get create you can just copy the file form googlestore to your
google could?
You can retrieve the original file name with
db.table.field_upload.retrieve(db.table(id).field_upload)
And you should be able to get your file db.table(id).field_upload_blob
Not sure all the particularities of googlestore thought...
You can have a look at the code of the gluon/dal.py .store(), .retrieve(),
.retrieve_file_properties method.
Hope it helps
