title: Can I add comments to a table or column using ActiveRecord Migrations?
body: <p>In MySQL (and other SQL databases), it can be helpful to add comments to a table or column whose purpose may be unclear. (Search MySQL's <a href="http://dev.mysql.com/doc/refman/5.1/en/create-table.html" rel="noreferrer">create table syntax</a> for "comment" for examples.)</p>
  
  <p>Is there a way to do this in an ActiveRecord Migration? I have tried this with no results.</p>
  
  <pre><code>create_table :stuff do |t|
    t.integer :obscure_column, :comment =&gt; "Explanatory comment"
  end
  </code></pre>
  
  <p>I'm using Rails 3.1.</p>
