ruby-on-rails – Rails在Helper中渲染部分

我遇到的第一个问题是帮助器返回每个循环而不是循环的结果.为了解决这个问题,我尝试让它返回一个包含循环结果的字符串.

def display_replies(comment)
    if comment.replies.count > 0
        string = ""
        comment.replies.each do |reply,index|
        string = string + (render partial: "comment",locals: {index: index}).to_s.html_safe
        end
        string
    end

在视图中调用<％= display_replies(reply)％>

当我查看我的视图时,返回并显示的内容是HTML,但它是转义的,因此是纯文本,它看起来像这样：

["<div class='c comment'>n<div class='profile'>n<img src='/assets/profile_image_sample.jpg'>n</div>n<div class='message'>n<div class='username'>Will Leach</div>nLorem ipsum dolor sit amet,consectetur adipiscing elit. Vivamus adipiscing purus et mi aliquet malesuada. Curabitur porttitor varius turpis eget sollicitudin. Lorem ipsum dolor sit amet,consectetur adipiscing elit. Ut dapibus consectetur tortor,nec aliquet lacus tempus vitae. Sed felis massa,dapibus in arcu sit amet,rhoncus condimentum eros. Etiam rutrum lectus in malesuada aliquam. Mauris vitae diam vel felis accumsan vulputate vel nec tortor. Nunc pretium hendrerit est,ut cursus ipsum commodo sit amet.n<div class='reply-link'>n<a href='#'>Reply to Comment</a>n</div>n</div>n</div>n"]

我只是想这是常规的非转义HTML.我在某处读到添加html_safe会解决这个问题,但唉它没有.

然后去哪儿？
