ImproperlyConfigured at /exam/selfdo/save_result

错误：

ImproperlyConfigured at /exam/selfdo/save_resultThe included urlconf '5' does not appear to have any patterns in it. If you see valid patterns in the file then the issue is probably caused by a circular import.

错误代码：

return redirect(reverse('exam:show_record',answer_record.pk)) url ： url(r'^selfdo/show_record/(\d+)$',views.show_record,name='show_record'),

原因：reversef反解析是传递参数的格式不正确

解决：

return redirect(reverse('exam:show_record',args=(answer_record.pk,)))以元组的方式传递
