Ao exibir os comentários em ordem DESC, os mesmos são duplicados na View. comment.rb scope :most_recent, order("created_at DESC")
jobs_controller.rb def show @job = Job.find(params[:id]) @comments = @job.comments.most_recent ...
_comment.html.erb
<% @job.comments.each do |comment| %>
<%= comment.name %> said: <%= simple_format comment.body %> Sent <%= time_ago_in_words comment.created_at %> ago <%= link_to "Destroy", comment_path(comment), method: :delete, confirm: "Are you sure?" %> <% end %>
