Python Django我在获取绝对url方面有很多问题

第一个问题：

当我创建新帖子时，我看到这条消息

（与关键字参数“{pk'：1，'slug'：”}”相反，未找到

。尝试了1种模式：

（['post/（？p\\d+）（：/（？p[\\w\\d-]）？/$）

第二个问题：

当我在readmore botton中调用get_absolute_url时，我看到这条消息

（'PostCreate'对象没有属性'get_absolute_url'）

两天来，我试图解决这个问题，我尝试了所有的解决方案，但我失败了

这是我的密码

从django.conf.url导入url
from.views导入（PostList、PostDetail、PostCreate、PostUpdate、ArticleDetailRedirect）
从django.url反向导入

谢谢

请每个问题只写一个问题。好吧，第一个问题你没有找到第一个问题的slug，第二个错误是正确的，你的

post create

没有get\u absolute\u url函数。请阅读并尝试创建一个可能的副本。对不起，先生，我的英语不好，我在这个网站上是新的在我提问之前，我已经阅读了一些信息……无论如何，使用know@permalink将其从django 1.10 im中删除，但问题仍然是在我创建帖子时（没有要重定向到的URL。请在模型上提供URL或定义get_absolute_URL方法）
