render_to_body

Called by render in AbstractController::Rendering which sets the return value as the response_body.

If no renderer is found, super returns control to ActionView::Rendering.render_to_body, if present.

def render_to_body(options)
  _render_to_body_with_renderer(options) || super
end

def _render_to_body_with_renderer(options)
  _renderers.each do |name|
    if options.key?(name)
      _process_options(options)
      method_name = Renderers._render_with_renderer_method_name(name)
      return send(method_name, options.delete(name), options)
    end
  end
  nil
end
def self._render_with_renderer_method_name(key)
  "_render_with_renderer_#{key}"
