Railsコントローラからアンカータグにリダイレクト

Question

私は、多態性の関連付けとしてコメントテーブルを使用しています。私はコメントを保存し、それぞれの関連するモデルにリダイレクトします。コメントを表示するためにアンカータグを自動的にスクロールダウンする必要があります。しようとしています以下のが、アンカータグは、あなたのアンカー文字列に#記号を削除し、URLヘルパーメソッド内anchor:を呼び出すURLに渡す

@comment = @commentable.comments.new comment_params 
    @comment.user = current_user 
    @comment.save 
    redirect_to @commentable, :anchor => '#comments'

Answer 1

されていません。redirect_to comments_path(anchor: 'anchor_tag')を

Answer 2

大丈夫、レールよりDOCurl_for()メソッドは、指定されたオブジェクトのURLを返す必要があります。

redirect_to "#{url_for(@commentable)}#comments" 

そのネストされた場合は、url_for([@product, @comment])
