表单集validate_min无法正常工作 [英] Formsets validate_min is not working properlly

问题描述

我有一个包含多个表单的表单集:

I have a formset with multiple forms:

PodFormSet = forms.inlineformset_factory(parent_model=PodP, model=Prod, form=PofModelForm, min_num=1, max_num=4,validate_min=True, extra=3)

问题在于validate_min无法正常工作:

The issues is that validate_min is not working properly:

如果用户填写的不是第一张表格，则validate_min无效，例如无效，这是无效的，因为至少填写了一张表格，但第一张表格却没有.

If the user complete another form than the first one, validate_min doesn't work, say is invalid, which is not, because at least a form is completed but not the first one.

如何覆盖/修复此行为?

How can I override/fix this behavior ?

推荐答案

根据我的记忆(如果我错了，请纠正我)，Django中的表单集不够聪明，无法针对乱序表单进行验证.这意味着如果 min_num>验证期望索引( id )为0的形式存在.0 ，您将不得不重新设置表单索引的格式.这通常是在前端完成的.

From what I remember (please correct me if I'm wrong) formsets in Django are not clever enough to validate against out-of-order forms. It means that validation expects form with index (id) 0 to be present if min_num > 0 and you will have to re-format forms' indices. This is usually done on the front-end.
