私はこのGeocoder Railscastに従いました & ユーザーが経度と緯度の座標を返さない誤った住所を入力した場合に、Geocoder Gem によって返される経度と緯度の座標に検証を追加できるかどうかを確認するために、それをいじっています。
以下のコードでこれをある程度まで機能させることができましたが、正しい住所を入力すると、経度と緯度の座標が返されたとしても、フォームを初めて送信したときにユーザーに検証エラーが表示されます。ユーザーがフォームを 2 回目に送信すると、機能します。
ユーザーがフォームを送信したときに経度と緯度の座標はありませんが、ジオコーダーの宝石が座標を返したときに2回目のラウンドがあるため、これが起こっていると思われます。
私のコードに何か問題がありますか、それとも別の方法でアプローチする必要がありますか?
