Reconstructing a chunked file in Rails

Question

I'm trying to build an HTML5 file uploader that supports large files via chunks. I've found enough documentation online to work with the frontend side of things but I see zero info about how to reconstruct the chunks once they hit the server (I'm using Rails.) Any help?

Answer 1

So you have multiple files containing a chunk of the large file? Then just do

File.open("file", "w") do |large_file|
  %w(file1.chunk file2.chunk file3.chunk).each do |chunk| # %w() creates an Array
    large_file.write(File.read(chunk))
  end
end
