Hi, I’m going through the Depot tutorial in the book “Agile Web  
Development with Rails” and I can’t even get past the very first step.  
I’m getting the following error:

“Before updating scaffolding from new DB schema, try creating a table  
for your model (Product)”

when I try to run "ruby script/generate scaffold Product Admin.

I have a table called “products” created in MySQL database  
depot\_development and so it’s not a name mismatch problem. I google’d a  
around and found that people who ran into this problem eventually  
“fixed” it by not using a MySQL password. So I removed my MySQL user  
password and the scaffold command worked. Is there a correct way to fix  
this problem? I don’t want to have an empty password for my sql  
account. Thanks.

I’m running ubuntu 6.06, ruby 1.8.4, rails 1.1.4, gems 0.9.0 if that  
matters.
