with the render
<div class="post"> <p>Doing nothing as usual</p> <a data-remote="true"
href="/comments/new?comment%5Bcommentable_id%5D=14&comment%5Bcommentable_type%5D=Post">Comment</a></div><div
class="post" id="post_14"></div>
$(document).on('turbolinks:load', function(){
$('#post div').click.(function(){
var elm = $(this);
elm.append('<%= form_for @comment do |f| %> <%= f.hidden_field
:commentable_id, value: @comment.commentable_id %><%= f.hidden_field
:commentable_type, value: @comment.commentable_type %> <div class="field
form-group"> <%= f.text_area :body, class: 'form-control' %> </div>
<div class="field form-group"> <%= submit_tag "Post
comment", class: 'btn btn-primary' %> </div> <% end %>');
});
});
