Posting an array of uploaded files

[louismrose]

Hi,

Thanks so much for Rack::Test; it's an incredibly useful library for me.

I think I might have uncovered a bug. I'd like to be able to specify an array of file uploads as params to a post request:

foo = Rack::Test::UploadedFile.new('foo.txt', 'text/plain')
bar = Rack::Test::UploadedFile.new('bar.txt', 'text/plain')

post "photos", :photo => { :file => [foo, bar]}

But in the controller, I receive the following params:

{"photo"=>{"file"=>[{"foo"=>"", "bar"=>""}]}, "action"=>"create", "controller"=>"photos"}

When posting a single file, the file is available in the params, as expected:

{"photo"=>{"file"=>#<File:/var/folders/QR/QR1Z8LNdGlaaW1vRT-ls2E+++TI/-Tmp-/RackMultipart20100322-9449-1o9a6i1-0>}, "action"=>"create", "controller"=>"photos"}

I'm happy to try a patch, but thought I'd ask whether I'm doing something stupid first!

Thanks very much.

I've looked at this some more, and think it's a problem with Rack::Test::Utils#build_multipart.

I've added some specs for this case and they're passing here:

I'll also send a pull request :)

Any news about this? louismrose's diff also fixes a problem with rails' foo_ids[] parameters for me.

Thanks!
