Re: [Jython-users] Django-jython problem when rendering admin user detail template

[Diego M. <dmu...@gm...>]

I made this question in StackOverflow to get answers and comments:

http://stackoverflow.com/questions/33637913/django-unicode-issue-with-datetime-in-jython-with-sqlite-jdbc

It seems there is a bug when reading the info provided by the JDBC from
django. The format that django gets is not the correct, as you can see in
the screenshot I attached in the question.
