title: Django ForeignKey form field: display value
body: <p>I might just be having a brain fart, but I seriously can't figure this out. How do I get display the values of <code>ForeignKey</code> fields from a bound form in a template? <code>{{ field }}</code> renders a widget, <code>{{ field.value }}</code> returns the <code>pk</code>, and I need the model itself.</p>
  
  <p>I am writing a custom template for django-crispy-forms; which is why I only get a form field in my context, but not a model field.</p>
