If it's a layout object, we call its render method, otherwise we instantiate a BoundField and render it using default template 'CRISPY_TEMPLATE_PACK/field.html' The field is added to a list that the form holds called `rendered_fields` to avoid double rendering fields. :param form: The form/formset to which that field belongs to. :template: Template used for rendering the field. :layout_object: If passed, it points to the Layout object that is being rendered.
