来自模型的Django选择表

好吧，我已经被困在这个标签系统上好几个星期了

我创建了一个django网站，让客户能够为我们翻译标签。我正在创建一个表单，其中客户选择他们希望创建相应翻译的项目代码。这意味着表单从模型中获取它的选择数据。当选择一个项目代码时，我希望能够获取所选的项目代码，并将用户反转到与该项目代码匹配的url中

目前，我正在使用

modelmultipechoicefield

从模型中获取数据。这是可行的，我能够以HTML格式显示数据。但是，我无法使用

cleaned_data

获取数据，因为它只返回整个queryset请求

这意味着我得到了错误

NoReverseMatch at /labelcreator/
Reverse for 'create_label' with keyword arguments '{'pk': <QuerySet [<Label: 13272432 Collar>]>}' not found. 1 pattern(s) tried: 
['labelcreator\\/(?P<pk>[0-9]+)\\/create_label\\/$']

非常感谢您提供的任何帮助

我不明白您为什么在这里使用多回声冰场。您希望选择单个标签，然后重定向到其“创建标签”页面；您应该使用ModelChoiceField。

是的，我现在很清楚这一点。我已经纠正了这一点。虽然我仍然无法从数据中获得所需的信息
