title: Ruby on Rails: models, migrations and getting an overview
body: <p>I've recently started using Ruby on Rails, after previously using Django for web development. I'm finding myself quite liking the emphasis on migrations (which on Django is an afterthought), but am a bit concerned by the following:</p>
  
  <ul>
  <li>in Django, using a library like South, the migrations are automatically generated from the change you make to the models. So examining a single file or directory is enough to see the current definition of all your models</li>
  <li>in Rails, AFAIU, app/models/*.rb only contain those models' methods; the fields are scattered throughout db/migrations.</li>
  </ul>
  
  <p>I suppose one could be disciplined in naming the migration files, and so it is doable to find all migrations pertaining to a given model, but still, once you get to, say, <code>m</code> models with <code>n</code> migrations each, that's a lot to keep track.</p>
  
  <p>There must be a way to inspect the current state of a particular model -- fields and methods both -- without the drudgery; could a more seasoned RoR developer enlighten me?</p>
