ActionView::TemplateError (undefined method `name' for nil:NilClass)

Question

I'm receiving the following error on my log:

ActionView::TemplateError (undefined method `name' for nil:NilClass) on line #18 of app/views/notices/_nsv_data.html.erb:

The code:

<table border="0" cellspacing="0" cellpadding="0">
<% System.get_systems_in_display_order.each do |sys| -%>
    <tr>
        <td>
          <%= check_box_tag "systems[][id]", sys.id, nsv_data.has_system?(sys.id) %>
          <%= sys.name %>
          <% if sys.can_has_version? -%>
              <br/>
            <% options = options_for_select( sys.get_system_version_select_options, nsv_data.system_version_ids( sys.id ) ) -%>
            <%= select_tag "system_versions[#{sys.id}]", options, { :multiple => true, :size => 5, :id => "system__versions", :class => "system__box" } %>
          <% end -%>
      </td>
  </tr>
<% end -%>
<tr>
    <td>
        <%= check_box_tag "has_other", 1, nsv_data.has_other_system? %>
        Other <%= text_field_tag "other_system[name]", nsv_data.other_system.name %>
    </td>
</tr>

The data which I'm trying to process is:

How is nsv_data populated? Because obviously nsv_data.other_system is null. — Marc Talbot
When you are submitting your form you are passing two different hashes one notice and another one is other_system. Are you assigning other_system to nsv_date in your controller? — Ajay Kumar Guthikonda

Just add sys.try(:name). You might want to check this out too.
