Django默认情况下，按字母顺序对模型进行排序。因此，Event应用模型的顺序为Epic、EventHero、EventVillain、Event

假设你希望顺序是

EventHero、EventVillain、Epic、Event。

用于呈现后台indxe页面的模板为admin/index.html，对应的视图函数为 ModelAdmin.index。

def index(self, request, extra_context=None):
  """
  Display the main admin index page, which lists all of the installed
  apps that have been registered in this site.
  """
  app_list = self.get_app_list(request)
  context = {
    **self.each_context(request),
    'title': self.index_title,
    'app_list': app_list,
    **(extra_context or {}),
  }
  request.current_app = self.name
  return TemplateResponse(request, self.index_template or
    'admin/index.html', context)

默认的get_app_list方法用于设置模型的顺序。

def get_app_list(self, request):
  """
  Return a sorted list of all the installed apps that have been
  registered in this site.
  """
  app_dict = self._build_app_dict(request)

  # Sort the apps alphabetically.
  app_list = sorted(app_dict.values(), key=lambda x: x['name'].lower())

  # Sort the models alphabetically within each app.
  for app in app_list:
    app['models'].sort(key=lambda x: x['name'])
  return app_list

因此，可以通过覆盖get_app_list方法来修改显示顺序：

class EventAdminSite(AdminSite):
  def get_app_list(self, request):
    """
    Return a sorted list of all the installed apps that have been
    registered in this site.
    """
    ordering = {
      "Event heros": 1,
      "Event villains": 2,
      "Epics": 3,
      "Events": 4
    }
    app_dict = self._build_app_dict(request)
    # a.sort(key=lambda x: b.index(x[0]))
    # Sort the apps alphabetically.
    app_list = sorted(app_dict.values(), key=lambda x: x['name'].lower())
    # Sort the models alphabetically within each app.
    for app in app_list:
      app['models'].sort(key=lambda x: ordering[x['name']])
    return app_list

以上代码app['models'].sort(key=lambda x: ordering[x['name']])用来设置默认顺序。修改后效果如下。
