active record wants root password, not sure why ..

When I run a command program (rails 3/ruby 1.9.2) as this:

class MsdsAttr < ActiveRecord::Base
  include MsdsAttrModule
   belongs_to :attribute_record, :polymorphic => true
  has_many :attribute_values, :foreign_key => 'attribute_id'
  has_many :alt_values, :as => :alternative
  has_many :msds_ingredients
end

ActiveRecord::Base.establish_connection(
:adapter => "mysql",
:host => "localhost",
:database => "univ_parse_dev",
:user => "PZZ",
:password => "PZZ"
)

attr = MsdsAttr.find(:first)

I get the error below even though I didn't try to connect using root.
Running rails server/console etc doesn't have this problem ..
