I'm render posts/index from a page called page.html.erb in the world
controller and that in turn renders index action in posts controller and
_index partial which in turn renders _post.html.erb The javascript anchor
tag is in the top level view, page.html.erb The javascript has no effect on
the html rendered No comment links displayed Thanks in advance
_post.html.erb
<%= div_for(post, class: 'post') do %>
<%= simple_format post.content %>
<% unless post.attachment.blank? %>
<%= image_tag(post.attachment, height: 250) %><br>
<% end %>
<%- end -%>
$(document).on('turbolinks:load', function(){
$('#posts div').each(function(){
var elm = $(this);
elm.append('<a href="/comments/new?post_id=' +
elm.attr('id').split('_')[1] + '">Comment</a>');
});
});
