Hello,
My first post here. I''m quite new to Ruby.
I''m making a Flash application that loads external files
from other servers onto the user''s hard disk.
That''s why I need a way to connect to the remote locations
over absolute http links; so I can monitor the progress inside
my Flash app. So this code should act as a file serving proxy.
Flash has some security restrictions, that will not allow the
loading of external files from other domains.
What I''ve got is this (not working, throws an error).
I used this file as an example:
"Cannot read file http://www.twin-diamonds.com/pic/rubies.jpg"
class StreamDataController < ApplicationController
def index
send_file(params[:file],:filename => params[:name],
:stream => ''true'', :buffer_size =>
''4096'')
end
end

So ruby tries to open that string as a local filename.

I think that leaves me with the same issue, no ? I will have to download the file first to my own server. And then serve them to my clients. The same thing happens with send_data, but only to the server''s memory, in stead of writing the data to the hard disk. The good thing is that I can cache the files this way. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Maybe some other background process on your server could handle a request like this, but I don''t think it will work from within Rails. Although, it''s disturbing that I think that is the first time I have ever said that. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

If you want to use the same filename as the one being downloaded, try something like this, which will get everything to the right of the last ''/'' in the url. url = ''http://foo.com/index.html'' filename = url.split(''/'').last full_path = "#{RAILS_ROOT}/tmp/#{filename}" File.open(full_path, ''r+'') {|f| ... } -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Alex, is this a typo ?
File.open(filename, ''r+'') do |f|
f.write data.read
end
shouldn''t this be:
File.open(filename, ''w'') do |f|
f.write data.read
end
When I try this it gives me "can''t convert String into
Integer"
