Question

我使用宝石Cocoon作为嵌套表格，这个表格没有提交...... 我做错了什么？谢谢你

_form.html.erb

<div class="container">
  <div class="row">
    <%= simple_form_for @event do |f| %>
    <div class="col-xs-12">
      <h3>Your event to share</h3>
      <%= f.input :name, label: "Event's name" %>
      <%= f.input :total_price, label: "What is the total price" %>
      <h3> Add your friends to share the bill</h3>
      <div id="participants">
        <%= f.simple_fields_for :participants do |participant| %>
          <%= render "participants_fields", f: participant %>
        <% end %>
        <div class="links">
          <%= link_to_add_association "add a friend", f, :participants, partial: "participants_fields", class:"btn btn-primary" %>
        </div>
      </div>
        <%= f.button :submit %>
    </div>
  <% end %>
  </div>
</div>

<div class="nested-fields">

Answer 1

我使用本教程几小时前用cocoon gem实现嵌套表单。你可能会发现它很有用。 https://www.youtube.com/watch?v=56xjUOAAZY8

要深入了解如何创建嵌套表单，您还应该看到有关如何在没有gem的情况下执行此操作的视频。 https://www.youtube.com/watch?v=pulzZxPkgmE

Answer 2

我错过了这种关系 has_many :participants, inverse_of: :event

我添加了has_many：参与者，依赖:: destroy

嵌套表单未保存
