title: Rails DB Migration - How To Drop a Table?
body: <p>I added a table that I thought I was going to need, but now no longer plan on using it. How should I remove that table?</p>
  
  <p>I've already run migrations, so the table is in my database. I figure <code>rails generate migration</code> should be able to handle this, but I haven't figured out how yet.</p>
  
  <p>I've tried:  </p>
  
  <pre><code>rails generate migration drop_tablename
  </code></pre>
  
  <p>but that just generated an empty migration.</p>
  
  <p>What is the "official" way to drop a table in Rails?</p>
