error in mySQL.
The error reads,

"> ruby script/generate scaffold Product Admin

exists test/functional/
dependency model
exists app/models/
exists test/unit/
exists test/fixtures/

identical test/unit/products.ywl
identical test/fixtures/product.yml
#28000Access denied for user 'root'@'localhost' (using password: NO)".

I have done this several time and continue to get the same error. Is

chat to help me with my problem, if possible.

My config/database.yml files shows,

# MySQL (default setup). Versions 4.1 and 5.0 are recommended.
