Difficulty Rendering Partial from another View

I am having trouble rendering a partial on Rails 4.2.1 There are no errors in the Rails Server logs and no output in the view. I have removed the as: option and the result is the same. Even if I hardcode the partial, the view does not display the information and the server log shows no errors.

app/views/registry_requests/_index.html.erb

<p><%= request.vehicle.make %></p>

app/views/users/_admin.html.erb

<!-- Columns -->
<div class="row">
  <!-- Dashboard -->
  <%= render 'admin_panel' %>

  <!-- Body Content -->
  ...

    <!-- Widgets -->
    ...
          <%= render partial: "registry_requests/index", collection: @registry_requests, as: :request %>

        ...
      <!-- Blog Feed -->
      <div class="col-sm-6">
        <div class="admin-widget">
          <h1 class="widget">Recent Blog Posts</h1>
          ...
        </div>
        <a class="admin-widget-link" href="blog_create.html">Create Post</a>
      </div>
      <!-- Current Moderators -->
      <div class="col-sm-6">
        <div class="admin-widget">
          <h1 class="widget">Current Moderators</h1>
          ....
        </div>
        <a class="admin-widget-link" href="#">Manage Moderators</a>
      </div>
    </div>
  </div>
</div>
