modelformset_factory错误
“禁止在未明确定义“字段”或“排除”的情况下调用modelformset_factory。”
我想创建一个动态表单，其中包含多个使用jQuery添加或删除的输入字段。但是当我尝试运行代码时出现错误。我把代码写下来了，请检查并帮助我解决这个问题。 谢谢
我遵循一个教程和Github代码。这是链接

我想在我的项目中添加多formSet。我遵循了https://github.com/shitalluitel/formset这个代码。但是，请在我的终端中显示此错误消息：“配置不正确：禁止在未明确定义“字段”或“排除”的情况下调用modelformset_factory。”
答案 0 :(得分：0)
inside views.py更改此行
journalEntryFormset = modelformset_factory( AccountsJournalVoucherEntery, form=AccountsPymtVoucherForm)
对此
journalEntryFormset = modelformset_factory( AccountsJournalVoucherEntery, form=AccountsPymtVoucherForm, fields={'field_1', 'field_2', 'field_....'})
