title: SQLalchemy: iterate through raw SQL query in template
body: <p>Have a code in function, which renders ResultProxy (as I understand), to template,  like this:</p>
  
  <pre><code>query = db_session.execute(serious_business_query) #raw sql
  return render_template('result.html', query=query)
  </code></pre>
  
  <p>I want to iterate through it in my template, but see nothing. How can I iterate through ResultProxy object? Or what should I pass to template to simply iterate through it?</p>
