title: How to change hash keys from `Symbol`s to `String`s?
body: <p>I am using Ruby on Rails 3.2.2 and I would like to "easily" / "quickly" change hash keys from <code>Symbol</code>s to <code>String</code>s. That is, from <code>{:one =&gt; "Value 1", :two =&gt; "Value 2", ...}</code> to <code>{"one" =&gt; "Value 1", "two" =&gt; "Value 2", ...}</code>.</p>
  
  <p>How can I make that by using less code as possible?</p>
