Angular无法访问返回的数据

在我的Angular/Rails应用中，我使用angular-file-upload gem上传电子表格。 https://github.com/danialfarid/angular-file-upload Angular无法访问返回的数据

我将电子表格传递给Rails后端，它处理数据并返回一个JSON数组。

该传递文件的向上角码是这样的：

$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; 
    }); 
};

导轨接受文件并处理它。我试图用返回它渲染JSON：{数据：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浏览器中的网络选项卡显示我的数据已经从Rails服务器返回，但角度似乎并不知道是什么与它做。在网络选项卡

返回数据

{"data":[{"chrom":4.0,"chrom_start":55593607.0,"chrom_end":55593607.0}, {"chrom":"4","chrom_start":55593609.0,"chrom_end":55593617.0},{"chrom":"6","chrom_start":133105152.0,"chrom_end":133105152.0}]}

我也试图改变的响应，但是这也没有工作。

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

不知道，但在我所见过的success的结构看起来像

.success(function(data, status, headers, config) { $scope.selector.tabledata = data; $scope.uploaded = true; });
