Python NoReverseMatch at/availability/1/edit/Reverse for'；可用性列表'；没有找到任何参数。已尝试：['；可用性\/（？P<；pk>；[0-9]+；）\\\/列表$'；]

当我尝试1）创建一个新对象（CreateView）或2）编辑一个现有对象（UpdateView）时，使用Django 3会出现这个错误。使用CBV和ModelForms

我探讨了有关Stackoverflow的类似问题。很多时候，这是关于模板缺少pk引用，但我三次检查，似乎不是这样

有什么想法吗

问题标题中的错误表示您在某处试图调用

反向

，而没有任何

主键

。

AvailabiltyList

视图在哪里？你能把它和你的其他观点一起发布吗？（另外，我没有看到您使用模型上的

staff_list

视图。）您需要使用

re_path

而不是

path

谢谢您的反馈！是的，我刚刚用AvailabiltyList视图更新了这个问题。我花了一些时间，意识到更新和删除模板都称为AvailabiltyList视图，但没有为其分配pk。出于某种原因，我认为错误与当前模板有关，但与更新和删除模板有关。我的不好。只是为了让其他处于类似情况的人更清楚：更新和删除模板称为AvailabilitList视图（例如：{%url'可用性\列表'%}}），但没有为其分配pk（例如：{%url'可用性\列表'pk=availability.pk%}）。我的困惑来自这样一个事实，即通常“列表”不需要pk分配。但是在这里，我使用视图AvailabiltyList名称中的“list”来指代特定用户的可用性列表（实际上是一个详细视图）。因此，它需要pk分配。
