Title Body

Just created a new blog app using rails 3.0 my model is simple: class Post < ActiveRecord::Base has_many :comments end class Comment < ActiveRecord::Base belongs_to :post end I used the commands: rails generate scaffold post title:string body:text etc. to create these files. Now I wanted to generated the db using: rake db:create I got the error: rake aborted! can't convert Fixnum into String Any ideas what the issue can be? I'm following this tutorial: http://sixrevisions.com/web-development/how-to-create-a-blog-from-scratch-using-ruby-on-rails/ Here is the trace: ** Invoke db:create (first_time) ** Invoke db:load_config (first_time) ** Invoke rails_env (first_time) ** Execute rails_env ** Execute db:load_config ** Execute db:create rake aborted! can't convert Fixnum into String /Library/Ruby/Gems/1.8/gems/mysql2-0.2.4/lib/mysql2/client.rb:36:in `connect' /Library/Ruby/Gems/1.8/gems/mysql2-0.2.4/lib/mysql2/client.rb:36:in `initialize' /Library/Ruby/Gems/1.8/gems/mysql2-0.2.4/lib/active_record/connection_adapters/mysql2_adapter.rb:14:in `new' /Library/Ruby/Gems/1.8/gems/mysql2-0.2.4/lib/active_record/connection_adapters/mysql2_adapter.rb:14:in `mysql2_connection' /Library/Ruby/Gems/1.8/gems/activerecord-3.0.0/lib/active_record/connection_adapters/abstract/connection_pool.rb:230:in `send' /Library/Ruby/Gems/1.8/gems/activerecord-3.0.0/lib/active_record/connection_adapters/abstract/connection_pool.rb:230:in `new_connection' /Library/Ruby/Gems/1.8/gems/activerecord-3.0.0/lib/active_record/connection_adapters/abstract/connection_pool.rb:238:in `checkout_new_connection' /Library/Ruby/Gems/1.8/gems/activerecord-3.0.0/lib/active_record/connection_adapters/abstract/connection_pool.r
