[RoR] Rake Migrate problem

ok, so I am moderately ok at rails yet I cant spot my problem, anyone good at rails/ruby,

I am trying to create table from rails, and here is my proccess:

First went to base of project and in terminal did:

ruby script/generate migration news_db

Then in the 001_news_db.rb I used.


class ContactDb < ActiveRecord::Migration
 def self.up
  create_table "news" do |t|
   t.column "id", :integer
   t.column "Content", :string
   t.column "Date Posted", :string
  end
 end

 def self.down
  drop_table :news
 end
end

Then in the base of project in terminal again I used:

rake migrate

and the out put I get is:

(in /home/5900/containers/rails/wopmod)
rake aborted!
uninitialized constant NewsDb

(See full trace by running task with --trace)

I know nokrev you can do rails so your my main hope.
