How to FTP in Ruby without first saving the text file -

-

since heroku not allow saving dynamic files disk, i've run dilemma hoping can me overcome. have text file can create in ram. problem cannot find gem or function allow me stream file ftp server. net/ftp gem using requires save file disk first. suggestions?

ftp = net::ftp.new(domain) ftp.passive = true ftp.login(username, password) ftp.chdir(path_on_server) ftp.puttextfile(path_to_web_file) ftp.close

the ftp.puttextfile function requiring physical file exist.

stringio.new provides object acts opened file. it's easy create method puttextfile, using stringio object instead of file.

require 'net/ftp' require 'stringio'  class net::ftp   def puttextcontent(content, remotefile, &block)     f = stringio.new(content)     begin       storlines("stor " + remotefile, f, &block)     ensure       f.close     end   end end  file_content = <<filecontent <html>   <head><title>hello!</title></head>   <body>hello.</body> </html> filecontent  ftp = net::ftp.new(domain) ftp.passive = true ftp.login(username, password) ftp.chdir(path_on_server) ftp.puttextcontent(file_content, path_to_web_file) ftp.close

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
