Question

I have this code

    #check if haus table is not blank   
      if !haus.blank?
             temp = Dir.mkdir("C:/thistemporary/")
         puts "tempfolder is created"
                haus.each do |file|
                dataname = file.name
                datavalue = file.data
            end
       end

I need to iterate through the haus table, that has “data column” (longblob) and “name column”(varchar), save each data with its name and value related inside the temp folder. How can I do this?

Thank you for any suggestion

Answer 1

if !haus.blank?
  tempdirname = "C:/thistemporary/"
  temp = Dir.mkdir( tempdirname )
  puts "tempfolder is created"
  haus.each do |file|
    dataname = File.join( tempdirname, file.name )
    datavalue = file.data
    File.open( dataname, 'w' ){ |f| f << datavalue }
    puts "#{dataname} is created"
  end
end
