私はスプリー コマースに取り組んでいます。active_sale_controller でいくつかのアクションを微調整しようとしています。いくつかの条件があります。条件が失敗した場合は、redirecting_to (:back) です。それ以外の場合は、次のステップに進みます。私が今直面している問題は、redirected_to (:back) を同じアクションで 2 回使用したことと、同じアクションで別のコントローラーに別の redirected_to をもう 1 つ使用したことです。ブラウザーに次のエラーが表示されます。
"Render and/or redirect were called multiple times in this action. Please note that you may only call render OR redirect, and at most once per action. Also note that neither redirect nor render terminate execution of the action, so if you want to exit an action after redirecting, you need to do something like "redirect_to(...) and return"."
ここに私のコードがあります

親切に私を助けてください!!!
