title: How do you add a field to a model AFTER gii code generation in Yii?
body: <p><strong>Situation:</strong><br />
  Yesterday I used gii to generate the code for my database table (mysql). I realized that my table needs a new field. </p>
  
  <p><strong>Question:</strong><br />
  What's the convention for adding a new field in the database table? Is there a checklist of things I need to do after manually adding the new table in mysql? Or is there a one push solution via gii?</p>
