重定向不一致

Question

我希望收到一条消息，该消息基于我单击的按钮的类型。取而代之的是，当我单击一个按钮并向我发送另一本不应显示的页面时，django的反应很奇怪。 Urls.py

当我在模板“ modifier_ue.html”中并单击一个按钮时，URL告诉我我在模板“ modifer_ue.html”中，但页面的呈现方式是“ ajouter_ue.html” 。因此，URL是正确的，但不是正确的呈现。该如何解决？

在avair做了几次测试之后，我意识到了ue_form（）。 is_valid将永远是错误的。造成这部分代码

>>>ue   = UE.objects.get(code_ue='INF401')
>>>ue_form = UEForms(instance=ue)
>>>ue_form.is_valid()
False

如何使实例作为参数传递，使表格始终有效？
