hello,  
I created a table in MySQL and generated a scaffold against the  
database with a product named “article” and the controller named  
“admin”, but when i try to load up the /admin view i get the  
following stack trace. I am new to rails so I am not sure about the  
nature of this error. Stack trace as follows.
