Not elegant, but finally works :
rows = db().select(db.mytable.id, db.mytable.upload_field,
db.mytable.upload_field_blob)
for i, row in enumerate(rows):
if row.upload_field != '' and row.upload_field is not None:
file = cStringIO.StringIO()
file.write(row.upload_field_blob)
db(db.mytable.id == row.id).update(
upload_field_upload=db.mytable.upload_field_upload.store(
file=file,
filename=db.mytable.upload_field.retrieve(row.upload_field)[0],
path=None))
db.commit()
filename =
db.mytable.upload_field_upload.retrieve(db.mytable(row.id).upload_field_upload,
nameonly=True)[1].split('/')[-1]
separate_folder_name =
db.mytable.upload_field_upload.retrieve(db.mytable(row.id
).upload_field_upload,
nameonly=True)[1].split('/')[-1].split('.')[2][:2]
path_tuple = (request.folder, 'uploads',
str(db.mytable.upload_field_upload), separate_folder_name)
path = os.path.join(*path_tuple)
if not os.path.exists(path):
os.makedirs(path)
f = open(os.path.join(path, filename), 'w')
f.write(row.upload_field_blob)
f.close()
Can't figure it out why file don't get wrote by .store() method... I mean
files get create with 0K, and I have to overwrite them with the code below
the db.commit()
:(
At least it works, if I can find why file don't get wrote in the first
place I may consider making a slice, but now it is to hacky... I get the
work done at least...
:)
