Damn Newbie! Multiple arguments to model method

Hi Mike,

Take a look at the stack trace if you have one. There's a lot of very
useful info in there normally. "1 for 2" means you're giving
something 1 argument when it takes 2. Since you haven't posted the
error message, I can't tell what that method is, but I'll take a wild
stab that you're calling #complete_task with 1 argument, when it
appears to take 2.

Regards,
George.
