title: Ruby On Rails Design Question: What if I make a mistake?
body: <p>I still learning Ruby on Rails, but have been wondering what happens if I make a mistake.  For example, if I scaffold and make a typo, what do I do?  If I don't do scaffolding, generate a model, rake db:migrate it and find out I need to ad a column or delete one, what do I do?  Is it better sometimes to use a third party manager on the database instead of letting RoR do it all?  I'm not sure how to feel about designing with RoR.  I can't be perfect with it every time!</p>
  
  <p>Thanks</p>
