title: Removing column is not working
body: <p>I am trying to remove a column from my database.  I'm running this</p>
  
  <pre><code>rails generate RemoveOccupancyFromSpaces occupancy:string
  </code></pre>
  
  <p>But then am getting this error message</p>
  
  <pre><code>Could not find generator 'RemoveOccupancyFromSpaces'. Maybe you meant 'resource_route' or 'devise:controllers' or 'active_admin:page'
  Run `rails generate --help` for more options.
  </code></pre>
  
  <p>Where am I going wrong here?</p>
