我有一个简单的表单,允许您选择用户并选择医院。表单成功提交。但是当我查看index.html.erb时,它看起来如下:[imgur] [1]。知道为什么“全名”和“医院”没有出现?

    <div class="field">
      <%= f.label :booking_reference %>
      <br/>
      <%= f.text_field :booking_reference %>
    </div>

    <div class="field">
      <%= fields_for :User do |user| %>
          <%= user.collection_select :user_id, User.all, :id, :full_name %>

      <% end %>
    </div>

    <div class="field">
      <%= fields_for :hospital do |hosp| %>
          <%= hosp.collection_select :hospital_id, Hospital.all, :id, :name %>
      <% end %>
    </div>

    <div class="actions">
      <%= f.submit %>
    </div>
<% end %>

不会像

那样
<div class="field">
      <%=  f.collection_select :hospital_id, Hospital.all, :id, :name %>
</div>

<div class="field">
      <%= f.collection_select :user_id, User.all, :id, :full_name %>
</div>

否则你打破了表单助手。

有疑问,请查看api:collection_select
