使用Roo gem/XLS，XLSX，CSV無法將Symbol隱式轉換爲Integer文件導入

我在rails 5中使用Roo Gem來處理數據導入。使用Roo gem/XLS，XLSX，CSV無法將Symbol隱式轉換爲Integer文件導入

我的CSV導入工作正常，但我認爲它更有效地使用XLS和XLSLX作爲最終用戶會更好地使用這些設備，我可以提供一個樣式化的導入模板供他們使用。

，當我嘗試導入表我收到錯誤如下：

Parameters: {"utf8"=>"✓", "authenticity_token"=>"X1k7+P2+YQtxJiKzuHZeErDCybH5jjCC1k/Q4OQwVL3hZ+ZEBdkxy8b9vXzGeHXhiMAKbukxvKsVbrQHh4FDFA==", "file"=>#<ActionDispatch::Http::UploadedFile:0x007fadab626f00 @tempfile=#<Tempfile:/var/folders/5z/7q_phgfd14d1cpgcpgwrgrj80000gp/T/RackMultipart20160905-12928-1hbqlew.xlsx>, @original_filename="User_import_excel.xlsx", @content_type="application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", @headers="Content-Disposition: form-data; name=\"file\"; filename=\"User_import_excel.xlsx\"\r\nContent-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet\r\n">, "commit"=>"Import"}

，我面對的另一個問題是，當我嘗試導入具有以前用戶在它來更新他們一個CSV文件大量，它只是給我一個錯誤，說電子郵件已被採取。如果我能得到這個錯誤的幫助，那太棒了！

我的用戶控制器導入操作：

def import 
    User.import(params[:file]) 
    redirect_to users_path, notice: "Users successfully imported" 
    end

我的用戶模型

# Accessible Attributes 
    def accessible_attributes 
    [:email, :f_name, :l_name, :telephone] 
    end 

    # XLSL Importer 
    def self.import(file) 
    spreadsheet = open_spreadsheet(file) 
    header = spreadsheet.row(1) 
    (2..spreadsheet.last_row).each do |i| 
     row = Hash[[header, spreadsheet.row(i)].transpose] 
     product = find_by_id(row["id"]) || new 
     product.attributes = row.to_hash.slice(*row.to_hash.keys) 
     product.save! 
    end 
    end 

    def self.open_spreadsheet(file) 
    case File.extname(file.original_filename) 
    when ".csv" then Roo::CSV.new(file.path, csv_options: {encoding: "iso-8859-1:utf-8"}) 
    when ".xls" then Roo::Excel.new(file.path, nil, :ignore) 
    when ".xlsx" then Roo::Excelx.new(file.path, :ignore) 
    else raise "Unknown file type: #{file.original_filename}" 
    end 
    end

請讓我知道，如果你需要的任何其他信息。任何援助與此將不勝感激！

所以，事實證明，我需要改變

when ".xls" then Roo::Excel.new(file.path, nil, :ignore)

到

when ".xlsx" then Roo::Excelx.new(file.path, file_warning: :ignore)

然後我不得不添加

gem 'roo-xls'

爲了導入xls文件。
