[英]Downloading workbook without saving it to disk rubyxl in Rails
Rails 4.2
RubyXL
我正在使用RubyXL创建工作簿。 我可以使用以下方法将其写入磁盘:
workbook.write("path/to/desired/Excel/file.xlsx")
然后使用以下内容下载它:
send_file(workbook.write(“ path / to / desired / Excel / file.xlsx”),options = {::文件名=>'myworkbook.xlsx',:disposition =>'附件'})
关于如何下载而不需要先将其保存到服务器的任何建议?
您可以将工作簿直接转换为字符串:
def get_worksheet_as_string
workbook = RubyXL::Workbook.new
# Fill workbook here or leave as is to download empty
send_data workbook.stream.string, filename: "myworkbook.xlsx",
disposition: 'attachment'
end
如果您在Sinatra工作:
get '/download-xlsx/?' do
content_type 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'
attachment(filename = "filename.xlsx", disposition = :attachment)
workbook = RubyXL::Workbook.new
# Fill the workbook with data
workbook.stream
end
认为这可能对在Sinatra工作的人有所帮助!
