Django内联表单集-仅保存第一个表单集

我试图动态添加表单集，但在提交表单集后，只保存第一条记录，而忽略其余记录

我是django新手，不知道这个问题是在django代码中还是在js代码中

models.py forms.py views.py 模板

{%extends“base.html”%}
{%load static%}
{%block title%}{%endblock%}
{%block content%}
样板
{%csrf_令牌%}
{{institute.management_form}}
{{form.as_p}}
{institute.forms%}
{{form.non_field_errors}}
{{form.errors}}
{{form}}
{%endfor%}
{{institute.empty_form}}
$（“#添加更多”）。单击（函数（）{
var form_idx=$（'#id_form-TOTAL_FORMS'）.val（）；
$（'#form_set'）。追加（$（'#empty_form'）.html（）。替换（/#u前缀uu/g，form_idx））；
$（'id_form-TOTAL_FORMS'）.val（parseInt（form_idx）+1）；
});
{%endblock%}

我原以为表单会保存所有记录，但它没有。

---

提交后如何使其保存所有记录？

表单集需要正确的前缀 在前缀中添加表单集名称 就这样

---

如果您有任何问题，请让我知道

对于我来说，它与

额外的

一起工作

像这样：

ClassFormSet = inlineformset_factory(ClassA, ClassB,
                                             form=ClassForm, extra=2)

---

试着弄清楚是否所有数据都按预期到达后端。双击签入视图以查看对表单集的处理。（您为表单集定义了两次

instance

？一次是在创建时作为参数，第二次是在\u有效吗？）他们使用

前缀：{{institute.prefix}}'，

而不是

前缀：{{formset.prefix}}

您的表单集名称是

institute

而不是

formset

。前缀设置正是问题所在！我还有一个问题，上面的内联表单集

extra

显示时没有默认值。知道原因是什么吗？
