残りのシステムで条件付き GETting のサポートを実装しようとしているときに、 fresh_when と stale? に遭遇しました。メソッド。
次のコードは 304 で正常に動作し、それ以上のレンダリングは行いません: format.html # show.html.erb } end end
ただし、1.xml にアクセスすると、リソースを 2 回レンダリングしようとします。
if stale?(:etag => resource, :last_modified => resource.updated_at.utc)
respond_to do |format|
format.html # show.html.erb
format.xml {
render :xml => @order.to_xml(:controller => self, :except => [:paid_at])
}
end
end
エラーメッセージ:
ActionController::OrdersController#show の DoubleRenderError
アクションごとに 1 回だけレンダリングまたはリダイレクトできます
