There's a few fundamental flaws here. You have the link to create a new comment inside the comment partial, not the post partial. The post needs to be the holder of this link, because there is only supposed to be one link per post that reads "Add a comment". Also, your link_to is missing the first argument -- there's no link text being supplied -- so I'm surprised if this template even compiles and displays.

You're also missing the surrounding HTML that I suggested to you when you asked how to get this into the "Ajax" format. Without those surrounding content_tag_for wrappers, the return from Rails has no idea where to insert the form or the updated comments. What I believe you need to end up with is something that looks like this (in _post.html.erb):

content_tag_for :div, post, 'comments' do

  content_tag_for :div, post, 'comment_form_holder' do
    link_to 'Add a Comment', new_comment_path(commentable_id: post.id, commentable_type: 'Post'), remote: true
  end

  render 'comments/comment', collection: post.comments

end

So what you should get is a structure like this:

<div id="post_comments_123">
  <div id="post_comment_form_holder_123">
    <a href="/comments/new?commentable_id=123&commentable_type=Post" data-remote="true">Add a Comment</a>
  </div>
  <div id="post_comment_345">
    Hello, this is a comment
  </div>
</div>

When someone clicks the Add a Comment link, because it is set to remote: true, the comments/new.js.erb template will render (by default), and as we discussed earlier, that template is set to update the appropriate container (post_comment_form_holder_123) with the new comment form contents. So the action is you click the link, and the link disappears, replaced by the form to add a comment.
