title: Renaming table in rails
body: <p>I want to rename a table... (any table.)</p>
  
  <p>I tried this line of code:</p>
  
  <pre><code>ActiveRecord::ConnectionAdapters::SchemaStatements.rename_table(old_name, new_name)
  </code></pre>
  
  <p>Here's the weird thing.  I know I got it working the first time, but now I get this error: undefined method `rename_table' for ActiveRecord::ConnectionAdapters::SchemaStatements:Module</p>
  
  <p>Was there something I need to set?</p>
