列出fields_中的属性为导轨形式

Question

我有一个form_for，它将fields_ in Chands_ for for party and Guest模型（聚会有很多客人，接受宾客的嵌套属性），并且客人属于聚会。我有一个form_ for我的聚会模型，它列出了聚会中每个客人的某些领域。我的表格工作正常，但我想简单地列出表格中每个客人的名称，因此看起来：

"Bob"
   attending: yes || no
   meal choice: chicken || veggie || pasta
"Susie"
  attending: yes || no
  meal choice: chicken || veggie || pasta

现在，我所拥有的只是：

attending: yes || no
meal choice: chicken || veggie || pasta
attending: yes || no
meal choice: chicken || veggie || pasta

我如何仅列出guest.first_name for fields_for的每个迭代？？？显然，我的Guests_form.first_name不起作用。

我表格的代码是：

您的聚会中的人：

<%= form_for @party do |f| %>
  <%= f.hidden_field :party_id, value: current_party.id %>
  <%= f.fields_for @guests do |guests_form| %>
  <%= guests_form.first_name %>
        <%= guests_form.label :attending, "attending?" %>
        <%= guests_form.radio_button :attending, true, :checked => true %>
        <%= guests_form.label :attending, "yes!", :value => true %>
        <%= guests_form.radio_button :attending, false, :checked => false %>
        <%= guests_form.label :attending, "no", :value => false %>
        <%=guests_form.label :meal_id, "meal choice" %>
        <%=guests_form.radio_button :meal_id, :checked => 1 %>
        <%= guests_form.label :meal_id, "chicken", :value => 1 %>
        <%=guests_form.radio_button :meal_id, :checked => 2 %>
        <%= guests_form.label :meal_id, "veggie", :value => 2 %>
        <%=guests_form.radio_button  :meal_id, :checked => 3 %>
        <%= guests_form.label :meal_id, "pasta", :value => 3 %>
    <%end%>
 <%= f.submit "submit", class: 'btn btn-primary btn-lg' %>
<%end%>

我以前从未使用过fields_for，因此任何帮助都将不胜感激！

您正在设计吗？如果是，则：

<% if user_signed_in? %>
  <p>Hello <%= current_user.first_name %>, let us know your preferences:      </p>
<%form_for @party do...
...
...
  <% end %>
<% end %>

您需要在隐藏的字段中捕获User_id，以便将其与选择一起保存。我会考虑使用Challocy的复选框或收音机按钮。
