title: Display attached pdf in browser within iframe - rails
body: <p>I have module which had a attachments functionality which uploads pdf files.
  I need to display stored pdf in the app within the browser/iframe and without downloading it. Is there a gem or chance which will show/read pdfs in rails.</p>
  
  <p>Note : The pdfs will contain images,text content etc.</p>
  
  <p>Thanks in advance</p>
