Thanks Nabil, I am also looking for something that is as simple as Django ORM but a standalone ORM that is not tightly coupled. I also like the ActiveRecord's syntax of Elixir. Kind regards, Joshua -- http://twitter.com/scrum8 On May 14, 7:51 am, Nabil Servais wrote:

Two choices: 1. Use apostrophe instead of a left or right signle quote when filling out the form. ;^) 2. Encode the description as utf-8 before writing it. description is almost certainly a unicode string. It gets coerced to be a bytes string when passed to python's (not django's) csv writer.
