两次嵌套属性form_for

Question

我正在寻找两次嵌套属性表单的解决方案。球队有几个球员，每个球员有几轮。我在模型中添加了accept_nested_attributes。 这种方式对我没用。

 <% 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

尝试将您的来电打印到.fields_for。

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