Ruby on rails rails通用字段\u用于强制子索引

模型

很明显，这将为每个人名=people\u form[person][name]生成相同的html。有没有办法让它插入索引，使person for中的每个for都是唯一的？没有Javascript黑客

例如，如果我能让它生成如下内容，那就太好了：

=form_tag :people_form do
 -@people.each_with_index do |person, i|
   =fields_for :person, person do |person_fields|
    =person_fields.text_field :name

比你想象的要简单

<input name='people_form[0][name]' />
<input name='people_form[1][name]' />

它起作用了吗？让我们知道不，不是。这将使用人员表单[人员表单[0]][名称]而不是人员表单[人员表单][0][名称]创建输入。

=form_tag :people_form do
 -@people.each_with_index do |person, i|
   =fields_for :person, person do |person_fields|
    =person_fields.text_field :name

<input name='people_form[0][name]' />
<input name='people_form[1][name]' />

=form_tag :people_form do
 -@people.each_with_index do |person, i|
   =fields_for "people_form[#{i}]", person do |person_fields|
    =person_fields.text_field :name
