Rails 4，check_box_tag 在ajax 渲染后没有将ids 传递到params hash

Question

在过滤表格中的结果之前，我的表单按照我的预期工作。

预期的功能是，允许用户选择多个对象，当用户单击“提交”按钮时（我已经重新将“提交”按钮标记为“交换”以阐明用户的功能”）

当我通过 ajax 过滤结果时，复选框和提交按钮在视图中仍然可见，但是当我单击“交换”时，所选对象不会与表单一起提交。 IE params[:event_ids] 不存在于 params 哈希中。我被难住了。

代码如下：

show.html.erb

<div class="jumbotron">
  <div class="container">
        <h1><%=@carpool.name%> Carpool!</h1>
        <p>View carpool specific events; Send Invites and Add Events if you are the carpool manager; View a list of all members in the carpool</p>
        <% if current_user == @carpool.manager %>
            <p>
                <a class="btn btn-primary btn-lg" href="<%=@carpool.id%>/events/new" role="button">Add Events</a>
                <a class="btn btn-primary btn-lg" href="<%=@carpool.id%>/invites/new" role="button">Send Invites</a>
            </p>
        <% end %>
  </div>
</div>

<div class="container">
    <div class="row">
        <div class="col-md-3">
            <%= render 'show_members_list' %>

        <div class="col-md-9">

尝试这样的事情

<%= check_box_tag "carpool[event_ids][]", event.id %>

您的控制台日志记录验证将出现的参数
