Question

我使用Comments表作为多态关联。当我保存评论并重定向到相应的关联模型。我希望它传递一个锚标记自动向下滚动以显示注释。我尝试以下但锚标签没有传递到网址

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

Answer 1

删除锚点字符串中的anchor:符号，并在网址助手方法中调用redirect_to comments_path(anchor: 'anchor_tag')：{{1}}

Answer 2

好吧，来自rails DOC url_for()方法应该返回给定对象的URL。

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

如果它嵌套了url_for([@product, @comment])

Rails从Controller重定向到Anchor标记
