ちなみにimageを設定しないで`submit`を押すと`create`がよばれimage以外のデータの保存は問題なくできますが、Params（下記）にimageのハッシュが存在していないのも気になるなと個人的に思っています。（別のモデルのフォームでは`null`を許容してるカラムのフォームに値を入れなくても `”カラム名”=>nil`のハッシュはParamsに含まれていた。）

`Dish`（料理）は親モデルのあたり、子モデル`Procedure`（作業手順）を`has＿many`の関係性となります。`dish＿id`を元にした`Procedure`のnew画面のフォームにてorder(作業順序 ：int),introduction(作業の具体的な工程 ：text),image(作業の画像 ：text)をparamsとして`create`で保存したいです。その際に`f.file_field`に画像（`image`）を指定してSubmitを行うと

- Createアクション内に`byebug`を仕込んでもそれが呼ばれる前にこの画面が出ているのでそもそも`create`アクションがよばれてない。

- file_fieldでimageを設定しないで`submit`を押すと`create`アクションがきちんとよばれimage以外のデータの保存は問題なくできますが、Params（下記）にimageのハッシュが存在していませんでした。

（別のモデルのCreateアクションの場合、`null`を許容してるカラムのフォームに値を入れないで送信した場合でも `”カラム名”=>nil`のハッシュはParamsに含まれていた。）
