Javascript Angular无法访问返回的数据

在我的Angular/Rails应用程序中，我正在使用Angular file upload gem上传电子表格

我将电子表格传递到Rails后端，它处理数据并返回JSON数组

向上传递文件的角度代码如下：

$scope.submitForm = function () {
  console.log('submit upload2');
  return $scope.upload = $upload.upload({
    url: '/api/batches/spreadsheet_upload.json',
    data: {
      id: 99,
      assembly: "xy"
    },
    file: $scope.file
  }).success(data, status, headers, config)(function () {
      debugger
    $scope.selector.tabledata = data;
    $scope.uploaded = true;
  });
};

Rails接受并处理该文件。我正在尝试使用呈现json:{data:spreadsheet_data}

def spreadsheet_upload
  Rails.logger.debug("here params: #{params}")
  spreadsheet = nil
  case File.extname(params[:file].original_filename)
    when '.csv' then spreadsheet = Roo::CSV.new(params[:file].path)
    when '.xls' then spreadsheet = Roo::Excel.new(params[:file].path, nil, :ignore)
    when '.xlsx' then spreadsheet = Roo::Excelx.new(params[:file].path, nil, :ignore)
    else raise "Unknown file type: #{file.original_filename}"
  end

  spreadsheet_header = spreadsheet.row(1)
  spreadsheet_data = []

  (2..spreadsheet.last_row).each do |i|
    row = Hash[[spreadsheet_header, spreadsheet.row(i)].transpose]
    spreadsheet_data.push(row)
  end
  render json: {data: spreadsheet_data}
end

Chrome中的“网络”选项卡向我显示数据已从Rails服务器返回，但Angular似乎不知道如何处理它

我也试着换一个回应，但这也不起作用

  }).success(resp)(function () {
    $scope.selector.tabledata = resp.data;
    $scope.uploaded = true;
  });

不确定，但我看到的

success

上的结构如下

.success（函数（数据、状态、标题、配置）{
$scope.selector.tabledata=数据；
$scope.upload=true；
});

  }).success(resp)(function () {
    $scope.selector.tabledata = resp.data;
    $scope.uploaded = true;
  });
