Rails Redirect to an Anchor Tag from the Controller

I am using Comments table as polymorphic associations. When i save the comment and it redirects to the respective associated model. I want it to pass an anchor tag to auto scroll down to display the comments. Am trying the following but the anchor tag is not passing to the url

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

Remove the # symbol in your anchor string and call anchor: within the url helper method: redirect_to comments_path(anchor: 'anchor_tag')


Alright, from rails DOC url_for() method should return URL of given object.

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

if its nested then url_for([@product, @comment])
