【问题描述】：

我知道这方面有一些线索，我一直在尝试不同的解决方案。

我有一个使用 DataTables gem 的非常简单的 1 页 rails 4 应用程序，当我加载页面时出现重新初始化错误 " DataTables 警告：table id=pivotal - 无法重新初始化 DataTable。有关此错误的更多信息，请参阅http://datatables.net/tn/3 "

在我的咖啡脚本中，如果我有这一行，它可以正常工作

jQuery ->
  $('#pivotal').dataTable

添加一个选项行，我得到了错误。我添加什么都没关系。该表只加载弹出错误。

jQuery ->
  $('#pivotal').dataTable
    bJQueryUI: true
    pagingType: "simple"

应用程序 JS

// Read Sprockets README (https://github.com/sstephenson/sprockets#sprockets-directives) for details
// about supported directives.
//
//= require jquery
//= require jquery_ujs
//= require dataTables/jquery.dataTables
//= require_tree .

应用程序 CSS

/*
 * This is a manifest file that'll automatically include all the stylesheets available in this directory
 * and any sub-directories. You're free to add application-wide styles to this file and they'll appear at
 * the top of the compiled file, but it's generally better to create a new file per style scope.
 *= require_self
 *= require jquery-ui
 *= require dataTables/src/demo_table_jui
 *= require_tree .

<table id="pivotal">  
  <thead>
    <tr>
      <th>Story Name</th>
      <th>Story Date Created</th>
    </tr>
  </thead>
 <tbody>
            <% @piv.each do |story| %>

            <tr>
            <td><%= story.name %>  </td>
            <td><%= story.created_at.strftime("%F") %>  </td>
            </tr>

            <% end %>
        </tbody>
</table>

【问题讨论】：

您是否尝试添加retrieve: true 选项？

代码中有两个jQuery -> $('#pivotal').dataTable 实例。

我只有 1 个咖啡脚本，其中有 1 行，我在哪里可以找到它的多个副本？

你能解决这个问题吗？ @ducati1212

【参考方案1】：

您需要将bDestroy : true 添加到datatable 选项，如下所示 jQuery ->

$('#pivotal').dataTable
  bJQueryUI: true
  pagingType: "simple"
  bDestroy: true
