“ Section4”对象没有属性“ user”

Question

我正在尝试自定义默认的django管理员，并在页脚中添加总字段。我不知道这是否是正确的方法。在删除模板中的{{block.super}}时，错误已删除，但我没有获得管理员的所有列表视图，仅得到了该模板的字段。

但是我也希望这些字段： image

@admin.register(Section4, site=admin_site)
class Section4Admin(ReadOnlyParamsMixin, admin.ModelAdmin):
   change_list_template = 'admin/section4/section4/total_review_count.html'

    def get_total(self, user):
      total_n = CarePlanNeed.objects.all().count()
      td = datetime.timedelta(29)
      last_review = timezone.now() - td

      total_review_upto_date = len(Counter([p['latest'] for p in
                     self.get_careplan(user).values('resident', 'aspect_of_life').annotate(
                         latest=Max('history_date')).filter(latest__gt=last_review).order_by() if p['latest']+td>timezone.now()]))
      total_review_tobe_updated = len(Counter([p['latest'] for p in
                     self.get_careplan(user).values('resident', 'aspect_of_life').annotate(
                         latest=Max('history_date')).filter(latest__gt=last_review).order_by() if p['latest']+td<timezone.now()]))
      total_review_added = self.get_careplan(user).values('resident', 'aspect_of_life')
      total_review_tobe_added = total_n * 17 - len(total_review_added)
      return total_review_upto_date, total_review_tobe_updated, total_review_tobe_added

  def  changelist_view(self, request, extra_context=None):
      total_review_upto_date, total_review_tobe_updated, total_review_tobe_added = self.get_total(request.user)
      my_context = {
        'total_review_upto_date': total_review_upto_date,
        'total_review_tobe_updated': total_review_tobe_updated,
        'total_review_tobe_added': total_review_tobe_added
      }
      return super(Section4Admin, self).changelist_view(request,
                                                     extra_context=my_context)

total_review_count.html：

{% extends "admin/section4/section4/change_list.html" %}
{% load i18n admin_urls %}
{% block result_list %}
{{ block.super }}
<footer style="color:blue;"> <p >The total review upto date: {{ total_review_upto_date}}<br> 
  </p>
  <p>The total review to be updated: {{ total_review_tobe_updated}}<br></p>
  <p>Total review to be added : {{ total_review_tobe_added }}</p>
</footer>
<p> {{ user }}</p>
{% endblock %}

错误：AttributeError at /section4/section4/ 'Section4' object has no attribute 'user' home/bishwa/PycharmProjects/johnson/section4/admin.py in changelist_view, line 430

我实际上想在django管理员的list_view的页脚中添加total_review_tobe_updated, total_review_tobe_updated, total_review_tobe_added。
