rails閱讀xls上傳的文件

Question

我已經上傳.xls文件，但我無法通過roo閱讀它。 在控制我有：

def create 
    name = params[:upload][:file].original_filename 
    directory = "public/uploads" 
    path = File.join(directory, name) 
    file = File.open(path, "wb") { |f| f.write(params[:upload][:file].read) } 
    flash[:notice] = "File uploaded" 
    file.inspect 
    Product.import(params[:upload][:file].original_filename)  
    redirect_to upload_path 
    end 

在模型：

def self.import(file) 

    spreadsheet = open_spreadsheet(file) 
end 


    def self.open_spreadsheet(upload) 
    directory = "public/uploads" 
    file = File.join(directory, upload) 
    case File.extname(file.original_filename) 
    when ".csv" then Csv.new(file.path, nil, :ignore) 
    when ".xls" then Excel.new(file.path, nil, :ignore) 
    when ".xlsx" then Excelx.new(file.path, nil, :ignore) 
    else raise "Unknown file type: #{file.original_filename}" 
    end 
    end 

但上傳可變我有串，我不能用文件的方法。我可以如何打開已上傳的文件供roo gem閱讀？

我介紹瞭如何用不上傳這裏使用的寶石工作：

你與像你這樣做的serveside原來的文件名着工作。
