Ruby on rails 无法读取属性'；分类'；未定义数据表的定义

for（j=0，jLen=oColumn.sorking.length；j如果您希望将列数据绑定到json，那么您应该将代码更改为：

$('#companyBoxList').dataTable
    sPaginationType: "full_numbers",
    bJQueryUI: true,
    bProcessing: true,
    bServerSide: true,
    sAjaxSource: $('#companyBoxList').data('source'),
    aoColumns: [{"mDataProp": "uId"},
                 .....the other data that you want to add such as length and width
               ]

语法错误…在我的初始表调用中缺少一个结束>。请检查我代码的第一行。
我不知道Rail，但datatables还可以，您能简单解释一下问题吗？不要放入
aoColumns:[null，null，null，null，null，null]
在我的javascript中，它出错了，声称它找不到oColumn对象。好吧，我知道原因是什么。参考我的答案，如果有其他问题，请发表评论，让我们一起前进，顺便说一句，因为我知道Rail非常棒。天哪，我很笨。在
调用开始时错过了
。哇，我不这么认为原因是这样的，但可能是这样。我发布了一些更改后的代码，希望能给您一些想法。另外请注意服务器返回的json格式
class BoxesDatatable
  delegate :params, :h, :link_to, :number_to_currency, to: :@view

  def initialize(view)
    @view = view
  end

  def as_json(options = {})
    {
      sEcho: params[:sEcho].to_i,
      iTotalRecords: Box.count,
      iTotalDisplayRecords: boxes.count,
      aaData: data
    }
  end

private

  def data
    boxes.map do |box|
      [
        box.uid,
        box.length,
        box.width,
        box.height,
        box.weight,
        box.trips
      ]
    end
  end

  def boxes
    @boxes ||= fetch_boxes
  end

  def fetch_boxes
    boxes = Box.order("#{sort_column} #{sort_direction}")
    boxes = boxes.page(page).per(per_page)
    if params[:sSearch].present?
      boxes = boxes.where("uid like :search or trips like :search", search: "%#{params[:sSearch]}%")
    end
    boxes
  end

  def page
    params[:iDisplayStart].to_i/per_page + 1
  end

  def per_page
    params[:iDisplayLength].to_i > 0 ? params[:iDisplayLength].to_i : 10
  end

  def sort_column
    columns = %w[uid length width height weight trips]
    columns[params[:iSortCol_0].to_i]
  end

  def sort_direction
    params[:sSortDir_0] == "desc" ? "desc" : "asc"
  end
end

jQuery ->
  $('#companyBoxList').dataTable
    sPaginationType: "full_numbers"
    bJQueryUI: true
    bProcessing: true
    bServerSide: true
    sAjaxSource: $('#companyBoxList').data('source')

$('#companyBoxList').dataTable
    sPaginationType: "full_numbers",
    bJQueryUI: true,
    bProcessing: true,
    bServerSide: true,
    sAjaxSource: $('#companyBoxList').data('source'),
    aoColumns: [{"mDataProp": "uId"},
                 .....the other data that you want to add such as length and width
               ]
