title: Can't make a migration
body: <p>I just reinstalled my Ubuntu, so I installed Ribu and Rails. All was going pretty well, but when I tried to make a model (database table) a couple errors showed up.
  Here's the error without trace:</p>
  
  <pre><code>cdr@ubuntu:~/pro$ rake db:migrate
  ==  CreateMonsters: migrating =================================================
  -- create_table(:monsters)
  rake aborted!
  An error has occurred, this and all later migrations canceled:
  
  undefined method `straing' for #&lt;ActiveRecord::ConnectionAdapters::TableDefinition:0x000000023cae90&gt;
  /home/cdr/pro/db/migrate/20121201195505_create_monsters.rb:4:in `block in change'
  /home/cdr/pro/db/migrate/20121201195505_create_monsters.rb:3:in `change'
  Tasks: TOP =&gt; db:migrate
  (See full trace by running task with --trace)
