How can I make a user the only one with permission to edit/delete their posts with CanCanCan?

I'm trying to build in logic that would allow a User to be the only one to be able to delete a post they make. I am using CanCanCan and followed their documentation as found on github.

This is my code

in my ability.rb

    class Ability
      include CanCan::Ability

      def initialize(user)
         can :destroy, Status, :user_id => user.id
      end
    end

in my application controller

    class ApplicationController < ActionController::Base
      protect_from_forgery with: :exception
      include CanCan::ControllerAdditions
    end

where i try and utilize cancancan

      <% if can? :destroy, @status %>
        <%= link_to "Edit", edit_status_path(status) %> |
        <%= link_to "Delete", status, method: :delete, data: {confirm: "Are you sure you want to delete this status?"} %>
      <% end %>

neither the "Edit" or "Delete" link shows up with my current if condition. Can anyone help me solve this?
