Param type Rack::Multipart::UploadedFile does not result in object of that type

[alexandergitter]

Declaring a parameter as Rack::Multipart::UploadedFile doesn't seem to actually yield a parameter of the same type. Instead I'm getting instances of Hashie::Mash.

The endpoint i use to test this looks as follows:

params do
  requires :avatar, type: Rack::Multipart::UploadedFile
end
post '/' do
  ...
end

That's correct. This hash is created by Rack::Request when processing multipart file data. Grape wraps it with Hashie for convenience.

post '/' do
  params.avatar.filename # => 'avatar.png'
  params.avatar.type # => 'image/png'
  params.avatar.tempfile # => #<File>
end

Not sure if this is documented anywhere in either library.

I'll leave this open, @alexandergitter feel free to suggest a doc improvement?

[alexandergitter]

Sure, I'll take a look at it later this week.

This is now documented in the readme. Close?

Closing.
