Rails Redirect zu einem Anchor-Tag vom Controller

Question

Ich verwende Comments-Tabelle als polymorphe Assoziationen. Wenn ich den Kommentar speichere, wird er auf das jeweils zugehörige Modell umgeleitet. Ich möchte, dass ein Anker-Tag übergeben wird, um automatisch nach unten zu blättern und die Kommentare anzuzeigen. Ich versuche die folgenden aber die Anker-Tag vergeht nicht auf die URL

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

Answer 1

Entfernen Sie die # Symbol in Ihrem Anker-String und anchor: innerhalb der URL-Helfer-Methode aufrufen: redirect_to comments_path(anchor: 'anchor_tag')

Answer 2

In Ordnung, von Schienen DOCurl_for() Methode sollte URL des angegebenen Objekts zurückgeben.

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

wenn seine verschachtelten dann url_for([@product, @comment])
