def todo_delete (request, pk):
# template = 'todo / todo_confirm_delete.html'
todo = get_object_or_404 (Todo, pk = pk)
todo.delete ()
Profile.objects.filter (Q (user = request.user.id)). Update (uncompletecount = F ('uncompletecount') - 1)
print ("todo", todo, delete ')
return reverse_lazy ('todo: todo_list')
错误

[30/May/2019 14:28:17] "GET /todo/60/delete/ HTTP/1.1" 500 59
感谢让我知道错误的原因以及解决方法
答案 0 :(得分：2)
您的视图todo_delete需要html响应，而您返回的是url。
我相信
的目的return reverse_lazy ('todo: todo_list')
是用于重定向到某个todo_list页面。
尝试使用redirect：
return redirect(reverse_lazy ('todo: todo_list'))
您明白了。我尚未测试代码，但我相信您会理解的。
