Question

I have the following code to display any comments that a user has made in a table on the users show page. The code works fine and a table is diplayed with all of the users comments and the permits they belong to. Currently the table displayed shows the permits in the order they were created by the user. I would like to arrange the table so that the permit column is displayed in alphabettical order instead of when they were created. Im not sure if I need to adjust this code or something in the controller.

  <% if @user.comments.exists? then %>

  <b>Comments:</b><br />
  <table>

  <tr>
<th>Permit</th>
<th>Comment</th>
  </tr>

  <% @user.comments.each do |comment| %>

  <tr>
      <td><%= link_to comment.permit.name, comment.permit %></td>
      <td><%= comment.body %></td>
  </tr>
  <% end %>
  </table>
  <% end %>

Use the ActiveRecord order method.

Check the official documentation here: http://guides.rubyonrails.org/active_record_querying.html#ordering

In your case, that would be something like:

<% @user.comments.order('name').each do |comment| %>
