title: passing variable to a string in a Rails controller
body: <p>I need to pass a variable into a string like this. </p>
  
  <pre><code>HTTParty.get(https://maps.googleapis.com/maps/api/place/search/json?location=-33.8670522,151.1957362&amp;radius=500&amp;types=food&amp;name=harbour&amp;sensor=false)
  </code></pre>
  
  <p>This works fine as a string, but I cant seem to get the syntax correct to make the parameters variables. Can someone please help me with the syntax.</p>
