投稿編集でルーティングエラーが発生

Question

投稿を編集する画面で、submitをクリックするとルーティングエラーになります。
編集後は"/books/id(27)"に移動したいのですが、エラーでは"/book/id(27)"になっています。
"/books/id(27)"になるように修正したいです。

Answer 1

<%= form_for(book, url:"/books/#{book.id}"), method: :patch do |f| %>
　↓
<%= form_for @book, url: book_path(@book), method: :patch do |f| %>

これで解決できました。
URL指定の仕方が良くなかったと思います。
ご回答頂きありがとうございました。

Answer 2

<%= form_for(book, url:"/books/#{book.id}"), method: :patch do |f| %>
を
<%= form_for @book, book_path(@book), method: :patch do |f| %>
にしてください。
もとのままでも　book を @book に変えればOKかも。

<%= link_to "Show", book_path %>　も　<%= link_to "Show", book_path(@book) %> に

Answer 3

redirect_to book_path(book.id)→redirect_to books_path(book.id)ですかね？

  def update
    book = Book.find(params[:id])
    if
      book.update(book_params)
      flash[:notice] = "You have updated book successfully."
      redirect_to books_path(book.id)
    else
      render :edit
    end
  end
