{% load material_form material_form_internal material_admin i18n %} 

{% admin_related_field_urls bound_field as bound_field_urls %} 

<div class="related-widget-wrapper"> 
{% render bound_field widget=field.widget.widget %} 
    {% part field label %} 
    <label for="{{ bound_field.id_for_label }}" class="related-widget-label"> 
     <span style="margin-right:5px">{{ bound_field.label }}</span> 
     {% if bound_field_urls.can_change_related %} 
     <a class="related-widget-wrapper-link change-related" 
      data-href-template="{{ bound_field_urls.change_related_template_url }}?{{ bound_field_urls.url_params }}"

У Вас есть ошибка в вашем коде, в строке # 138 в smart_selects\widgets.py:

File "C:\project\smart_selects\widgets.py" in render 
    138.     "id": attrs['id'], 

(Локальная переменная attrs не ДИКТ Это None.)
