title: scaffolding and updating attributes manually in ruby on rails howto?
body: <p>I was wondering if anyone knew how to update the files (adding/removing/updating an attribute) produced by using the scaffold generator in ruby on rails.</p>
  
  <p>For example:</p>
  
  <p>scaffold student name:string lastname:string</p>
  
  <p>so this will create a the associate files (controller,view,etc) with name and lastname as string attributes.  When you db:migrate the project, it'll create the table in the database.  However, say I want to update whether it be update it with an addition attribue (ex. studenId:integer) or if its removing or updating an attribute, how do you do that?</p>
  
  <p>I tired just updating the generated files, but when I do that db:migrate it still sets the schema that is generated to what is in the table.  Is there a built in script in rails that will update the table?</p>
  
  <p>Any advise appreciated?
  Thanks,
  D</p>
