ruby on rails-两次嵌套的属性form_for

Question

我正在寻找一个两次嵌套属性表单的解决方案。团队有几个玩家，每个玩家有几个回合。我在模型中添加了accept_nested_attributes。这种方式对我不起作用。

 <% form_for(@team) do |team_fields| %>
     ...SOME FIELDS...
   <% team_fields.fields_for :players do |player_fields| %>...SOME FIELDS...
      <% player_fields.fields_for :rounds do |round_fields| %>
         <%= round_fields.text_field :message%>
      <%end%>
   <%end%>
 <%end%> 

Answer 1

尝试打印对.fields_for的调用。

<%= player_fields.fields_for :rounds do |round_fields| %>
