[kforge-user] Error: unicode() argument 2 must be string, not None.

Wed Jan 20 11:55:49 UTC 2010

Hi Nick,

Thanks for your message.

Firstly, I should admit, I haven't been testing KForge with MySQL. I 
will start doing that, because there are clearly MySQL-specific issues 
that can't be ignored.

I just tried to setup KForge against MySQL. It fails, but with a 
different error ("BLOB/TEXT column 'name' used in key specification 
without a key length") from the error you reported.

The error you reported "unicode() argument 2 must be string, not None" 
was generated from within SQLObject's createTable() method. That error 
would pop up whenever the optional 'encoding' argument of the unicode() 
class exists, but is a null value. Looking though the SQLObject code, it 
appears that this should always be set. So I'm wondering, which version 
of SQLObject do you have?

I will fix KForge for MySQL, but not today. So if you have a deadline, 
using KForge at first with SQLite or PostgreSQL might be the way to go. 
It's possible later to switch database systems (dump KForge domain data, 
adjust db config, reload domain data) so you could start with SQLite, 
and then move to MySQL when we've fixed the issues you have highlighted.

At any rate, please let me know how you get on.

Best wishes,

John.
