i absolutely new ruby on rails , i'm following book that's written tutorial, bit outdated.

when run server , browse localhost:3000 not working right, following error: activerecord::connectionnotestablished

mysql installed in computer, databases created , of works in other example applications have been giving to.

this databases.yml file:

development:   adapter: mysql2   database: emporium_development   username: emporium   password: hacked  test:   adapter: mysql2   database: emporium_test   username: emporium   password: hacked

i made sure mysql2 gem installed this: gem install mysql2

shed light on me please.

first setup gems running

bundle install

then database needs created: 

rake db:create

if have pending migrations (and if don't can still run, won't anything):

rake db:migrate

this should setup database works, provided gave correct password.

note if have database want rid of, can run 

rake db:drop

and try create database again.
