Treebook app - only the owner of a status should be able to see edit or delete links

Hi,

I recently finished the "Build a Simple Ruby on Rails Application" project tutorial and started the next project section called "Building Social Features in Ruby on Rails" it seems that in the views (specifically the index and show views) all users can see 'edit' and 'delete' links for a status post. Putting a <% if user_signed_in? %> statement around the edit/delete links in the index and show views works for removing the links for non-signed in users but then any 'logged in user' could still see edit or delete links fo any other user's statuses.

This may be covered in future courses so forgive me if I'm jumping ahead. The actual functionality of editing or deleting another user's status posts can be negated by adding the following to the create, edit and update methods "@status = current_user.statuses.find(params[:id])" ... but how can those edit and delete links only be shown to the owner of a given status?

Here is what the relevant part of my status index view currently looks like:

<% if user_signed_in? %>
<span class="admin">
  | <%= link_to "Edit", edit_status_path(status) %> |
  <%= link_to "Delete", status, method: :delete, data: {confirm: "Are you sure you want to delete this status?"} %>
 </span>
 <% end %>
