title: How to return value unquoted in Ruby?
body: <p>I am trying to implement Watson callback function in Ruby on Rails and they say I should omit the quote in the return.</p>
  
  <p>I created get method to return what was received. The url is "<a href="http://someurl/api/v1/resoucename/results?somevalue=123123" rel="nofollow noreferrer">http://someurl/api/v1/resoucename/results?somevalue=123123</a>", I return 123123 as "123123"</p>
  
  <pre><code>resource :resoucename do 
     get :results do 
       return params[:somevalue]
     end
  end
  </code></pre>
  
  <p>How can I return a unquoted value?</p>
  
  <p>Watson says:
  <em>The request includes an Accept header that specifies text/plain as the required response type.</em></p>
  
  <p>If anyone has an idea how to return as it is, please share with me!
  Best</p>
