我想使用modelformset创建模型的多个实例。
但是当查询集为空且参数extra大于0时，它会引发此错误：

Exception Type: KeyError at /alta_socies/proces_alta_projecte_autoocupat/adreces/

我调试的违规行是：
AdrecesFormSet = modelformset_factory(AdrecaProjecteAutoocupat,
form=FormulariAdrecaProjecteAutoocupat,
can_delete=True)
任何提示？
答案 0 :(得分：0)
向导表单期待一个dits的dicts列表！问题出在views.py
中的其他地方
