NoMethodError: undefined method `each' for 5:Integer

Question

前提・実現したいこと

railsでseedファイルを作成しています。
origin_itemを作成中に以下のエラーメッセージが出ました。

発生している問題・エラーメッセージ

NoMethodError: undefined method `each' for 5:Integer

該当のソースコード

5.times do |n|
 @origin_item = OriginItem.create!(
  item_group_id: @item_group.id,
  title: "サンプルアイテム#{n+1}",
  overview: "アイテム#{n+1}",
  status: rand(0..1) )
end

ちなみに、item_groupは以下になります。

5.times do |n|
 @item_group = ItemGroup.create!(
  category_id: @category.id,
  icon: open("db/images/sample.png"),
  start_date: "2020/5/1",
  end_date: "2020/5/30",
  title: "チュートリアル#{n+1}",
  overview: "アイテムの購入について",
  status: rand(0..1) )
end

試したこと

eachのエラーから５個も繰り返せる配列がないとのエラーだと思い、5.timesの記載を消して試してみましたが、解決できませんでした。何か対処法あれば教えて頂きたいです。

[maisumakun]

エラーはどの行に出ていますか？（書かれているコードにeachがなさそうです）

[panda07]

エラーは seeds.rbの@origin_item = OriginItem.create!の行でています。
他のコントローラー等の設定をみるべきなのでしょうか？

[winterboum]

気持ちが悪いのは インスタンス変数が使われていること。。。
ということはエラーのでているloopの前にもcodeがあるとおもいます。
頭からそこまで載せてください。そこに何かあるのかもしれません

[panda07]

@origin_itemはどこかの関連でidを持って来るときのために一応設定しているだけで現在は使用しなくても良いものになっています。
ですので、@origin_itemはここでしか現在定義していないです。

[winterboum]

@item_groupのことを言ってます

[winterboum]

@origin_item = OriginItem.create! がどこにもみえませんが。。
この直後にあるということ？
@item_groupもないね。。。

それと、プログラムはここに載せられると読みにくいので、質問欄に<code>で書いて欲しい

[panda07]

失礼しました。見にくくなってしまい申し訳ありません。
次回から<code>に記載します。
@origin_itemはこの直後に記載しています。

[winterboum]

@item_groupは？

すみません。再度全部<code>で載せます。

[winterboum]

次回から<code>に記載します。　はどうなったの？

[panda07]

書き直したつもりだったのすが、変わっていなかったので少々お待ちください。
すみません。

[panda07]

質問投稿欄更新しました。
ご確認お願い致します。

[winterboum]

読みやすくなりました。
が、、、
可能性があるかなぁと思っていた「@item_groupにおかしな値が入っている」という線がなくなってしまった。
maisumakunさんの言われるように　eachがないですね。
となると RAILSかgemかのどこかで起きているので、エラーメッセージを全部載せていただかないとわからないです。

[winterboum]

/my-api/db/seeds.rb:185:in `block in <main>'
とあります。でも載っている seeds.rbは１３５行しか無いです。
もっと先に問題があるようです

[panda07]

すみません。いくつかitemと関係のないseedデータを追加したので、行数が増えてしまっています。エラーの箇所は@origin_itemのところであっています。

Answer 1

こちらの質問自己解決できました。モデルを再度確認したところカラム名が間違っておりました。
ご協力頂いたwinterboumさん、maisumakunさんありがとうございました。
