title: Altering table using the Symfony2 Doctrine2 console/generate feature?
body: <p>What I'm trying to figure out is how to add new fields to a table, using Symfony2 with Doctrine2.</p>
  
  <p>I used this to initially create the Entity:</p>
  
  <pre><code>php app/console doctrine:generate:entity --entity="MyMainBundle:ImagesTable" --fields="title:string(100) file:string(100)"
  </code></pre>
  
  <p>And I used this to create/update the tables on the database:</p>
  
  <pre><code>php app/console doctrine:schema:update --force
  </code></pre>
  
  <p>Now if I wanted to add new fields to the <code>ImagesTable</code> entity, is there an easy way to do it using the <code>console</code>, or do I have to manually edit the entity. I am just using 1 entity as an example right now, but in reality, there are many entities I'd be changing; so, there has to be an easier way to do it.</p>
  
  <p>I've been manually editing them to create relationships, so if there is an easier way to do that as well, that'd be great.</p>
  
  <p>I remember this being a lot easier with Symfony1.4 - all I had to do was create the database/tables using phpMyAdmin, and Symfony was able to generate the models with no issues.</p>
  
  <p>I really hope I'm missing something here, because this won't work if I have to manually edit every entity for every change.</p>
