Question

我正在尝试向我的数据表添加2个更多隐藏列，但我继续收到URI太大错误以及“错误类型错误：无法将nil转换为确切数字”

Started GET "/assets/datatables/emails_datatable.self-cd9ac92f42d16be45f44ff8a616bd1ed9ff6e16588934ecabaadfff5000e4db2.js?body=1" for ::1 at 2017-07-21 14:46:15 -0400

这是整个错误消息

这些是我的email_broadcasts_datatable.rb中指定的列（注释列是触发错误的列）

def data
  email_broadcasts.map do |broadcast|
    [
      broadcast.id,
      broadcast.email_clickthroughs_count,
      broadcast.email_abuse_reports_count,
      # broadcast.email_unsubscribes_count,
      # broadcast.email_opens_count,
      broadcast.status.titleize,
      broadcast.scheduled,
      broadcast.subject,
      broadcast.user.email,
      broadcast.updated_at.in_time_zone("Eastern Time (US & Canada)").strftime('%B %-d, %Y %l:%M%P'),
      link_to('', edit_email_broadcast_path(broadcast), class: "btn btn-primary fa fa-cog"),
      link_to('', email_broadcast_path(broadcast), method: :delete, data: {confirm: "Are you sure you want to delete this email broadcast?"}, :remote => true, class: "btn btn-danger fa fa-trash delete_email_broadcast")
    ]
  end
end

这也是我的数据表的javascript代码。

//Code for emails datatable

$(function() {

  $('#emails').DataTable({
    pageLength: 10,
    responsive: true,
    processing: true,
    serverSide: true,
    autoWidth: false,
    ajax: $('#emails').data('source'),
    dom: '<"html5buttons"B>lTfgitp',
    buttons: [
    { extend: 'copy'},
    {extend: 'csv'},
    {extend: 'excel', title: 'Emails'},

    customize: function (win){
      $(win.document.body).addClass('white-bg');
      $(win.document.body).css('font-size', '10px');

      $(win.document.body).find('table')
      .addClass('compact')
      .css('font-size', 'inherit');
    }
  }
  ],
  columnDefs: [

    render: function ( data, type, row ) {
      return data + ' ' + row[10] + ' ' + '<button type="button" class="btn btn-success" data-toggle="modal" data-target="#stats"><i class="fa fa-line-chart"></i></button>';
    },
    targets: 9
  },
    {
    targets: [ 0 ], //,9,10,11 
    visible: false,
    searchable: false
  },

  {
    render: function ( data, type, row ) {

      switch(data) {
        case "Draft":
        return "<span class='label label-primary'>" + data + "</span>"
        case "In Queue":
        return "<span class='label label-warning'>" + data + "</span>"
        case "Completed":
        return "<span class='label label-success'>" + data + "</span>"
        case "Processing":
        return "<span class='label label-info'>" + data + "</span>"
        default:
        break;
      }
    },
    targets: 4
  },
  {
    render: function ( data, type, row ) {

      if (data) {
                            //True
                            return "<span class='label label-success'>Yes</span>"
                          } else {
                            return "<span class='label label-danger'>No</span>"
                          }
                        },
                        targets: 5
                      },
                      {
                        orderable: false,
                        targets: [5,8,9]
                      }   
                      ],
                      order: [[0, 'desc' ]],
                      columns: [
                      { width: "0%" },
                      { width: "2%" },
                      { width: "2%" },
                      { width: "8%" },
                      { width: "8%" },
                      { width: "30%" },
                      { width: "18%" },
                      { width: "18%" },
                      { width: "12%" }
                      ]
                    });
});

这是我的HTML表格

<table id="emails" class="table table-striped table-bordered table-hover" data-source="<%= email_broadcasts_path(format: :json) %>">
  <thead>
    <tr>
      <th>Id</th>
      <th>Click Throughs</th>
      <th>Abuse</th>
    <!--  <th>Unsuscribes</th>
     <th>Opens</th> -->
      <th>Status</th>
      <th>Scheduled</th>
      <th>Subject</th>
      <th>Created By</th>
      <th>Updated</th>
      <th>Actions</th>
    </tr>
  </thead>
  <tbody>
  </tbody>
</table>

Answer 1

这是WEBrick本身的问题。它对URL长度有内部限制。

您应该运行另一个Web服务器，如Puma，Thin或Unicorn。

将以下内容添加到Gemfile以运行其中一个本地

group :development do 
  gem 'puma'
end

ERROR WEBrick :: HTTPStatus :: RequestURITooLarge在向数据表添加10列以上时
