記事1を参考にRailsでお仕事辞退機能(辞退理由を送信する)を実装中に以下のエラーに遭遇しました。
NoMethodError in Cancels#new
Showing /Users/me/environment/アプリ名/app/views/cancels/new.html.erb where line #1 raised:
undefined method `cancels_path' for #<ActionView::Base:0x0000000001d308>
recipient.public_send(method, *args, options)
^^^^^^^^^^^^
以下がコードになります。

<% end %>
記事2によると、
調べると、以上の「= form_with model: @review, local: true do |f|」のコードにおいては、form_with model: @review の箇所が内部的にpolymorphic_path(@review)というメソッドを実行しているそうで、 その実行結果がreviews_pathとなるのでそこでエラーが起きているらしい。
ということで、パスが意図せず作られてしまう(？)ことで発生するエラーのようです。
記事3では、アソシエーションの設定が上手くできていない可能性があると書かれており、チェックしてみましたが特におかしい点は見当たりませんでした。
記事2ではform_forで解決していますが、form_forは現在では非推奨なので、以下のようにしたところ一応エラーは出なくなりました。
app/views/cancels/new.html.erb
<%= form_with(url: job_cancels_path) do |f| %>
<%= f.text_area(:reason, placeholder: "辞退理由を入力") %>
<%= f.submit("辞退理由を送信") %>
<% end %>
