== AutoMigrations
 
Forget migrations, auto-migrate!
 
 
== Usage
 
Write out your schema (or use an existing one)
 
  $ cat db/schema.rb
 
  ActiveRecord::Schema.define do
 
    create_table :posts do |t|
      t.string   :title
      t.text     :body
      t.timestamps
    end
  
  end
 
  $ rake db:auto:migrate
 
  Created posts table
 
...a few days later
 
  $ cat db/schema.rb
 
  ActiveRecord::Schema.define do
 
    create_table :posts do |t|
      t.string   :title
      t.text     :content
      t.timestamps
    end
  
  end
 
  $ rake db:auto:migrate
  -- add_column("posts", :content, :text)
     -> 0.0307s
  -- remove_column("posts", "body")
     -> 0.0311s
