Rails Render Partial in Helper

Question

I have been trying to render one of my partials in a helper function located within my controller.

The first issue I encountered was that the helper was returning the e

To fix \n and [", we need to have .join after the loop. Like so:

Helper:

def display_replies(comment)
  if comment.replies.count > 0
    raw(
      comment.replies.map do |reply, index|
        render 'comment', index: index
      end.join
    )
  end
end

View:

<%= display_replies(reply) %>

Note that I removed all html_safe and replaced with raw. And instead of each loop, I used map, so we don't have to create variable string and return it after the loop.

Hope this helps!
