Rails comparison not working

In Rails, have a workorders table. Each workorder can have children workorders. I'm trying to create dropdown links to sibling workorders. I'm testing by looking at workorder.id = 30. It has a sibling workorder.id = 20. I don't want to display a link to the same workorder the user is looking at (30).

So I put in a test <% if child.id != @workorder %>. But, the 30 link still displays. I added some logger code to see what's going on.

This is my code:

<li class="dropdown-header">Siblings Links</li>
    <% Workorder.find(@workorder).parent.children.each do |child| %>
        <%= logger.info 'LOOK HERE ' %>
        <%= logger.info child.id %>
        <%= logger.info @workorder %>
        <% if child.id != @workorder %>
            <li><%= link_to child.id_desc, tasks_index4_path(:workorder_id => child) %></li>
        <% end %>
    <% end %>

The log shows:

LOOK HERE
30
30
LOOK HERE
30
20

Yet the link_to for 30 shows up.

Thanks for the help!

use @workorder.to_i in the comparison

@workorder presumably is a Workorder object. As such, in order to compare the @workorder to the child.id, you'll need to access the id attribute on @workorder in order to make the correct comparison:

<% if child.id != @workorder.id %>
