Files from file_field coming through as Array, not File objects

[radar]

Hello again,

I have a project at https://github.com/rails3book/edge-ticketee/tree/chapter_8 which has the features/creating_tickets.feature feature failing because files are not being passed correctly. You can duplicate this by running:

bundle install
bundle exec cucumber features/creating_tickets.feature:38

It will give this error:

Then I should see "speed.txt" within "#ticket .asset"
    Unable to find '#ticket .asset' (Capybara::ElementNotFound)
    ./features/step_definitions/web_steps.rb:29:in `with_scope'
    ./features/step_definitions/web_steps.rb:36:in `/^(. within ([^:]+)$/'
    features/creating_tickets.feature:45:in `Then I should see "speed.txt" within "#ticket .asset"'

If you inspect the parameters in the controller for ticket, namely the asset parameter, you'll see this:

"asset"=>["The blink tag can blink faster if you use the speed=\"hyper\" attribute."]

In previous versions of Rails, this always came through as a Tempfile object, and I think Paperclip is still expecting it to be that because it's not saving that file anywhere.

Hey @radar, we are close to Rails 3.1 release and there are a lot of issues. If you can help us pinpoint exactly were is the error, it would be great! I know it should be working automatically, but can you confirm if the form is being set to multipart?

[radar]

The form is automatically being set to multipart. If I set :html => { :multipart => true } in the form it does the same thing, but :html => { :multipart => false } (as expected) sends through the file names, not the content.

I will attempt to track down this issue today.

fffffffffuuuuuuuuuuuuuu

This seems to be another Rack::Test bug, as it works fine when running the application in development mode.
