title: Render partial to String in view helper
body: <p>How can I render a partial to a String in Ruby on Rails 4.2, since <code>render_to_string</code> is deprecated?</p>
  
  <p>Something like:</p>
  
  <pre><code> rendered_string = render_to_string partial: 'forgotten_orders/soonest_manufacturing_date', locals: { forgotten_order: forgotten_order, soonest_manufacturing_date: soonest_manufacturing_date }
  </code></pre>
