Rack, Paperclip, grape file upload example

[Loren Harrell]

Can someone please reply with working example processing a file upload request? I can't seem to get my api to properly upload with grape.

Here is what I have so far:

  namespace...

    post ':person_id/avatar' do

    person = Person.find_by_id(params[:person_id])

    file = params['image_file'] ? params['image_file']['tempfile'] : nil

    unless file.blank?

      person.avatar = file

      person.save!

      end

    end

Then when I use:

curl -F "image_file=@/home/me/myfile.jpg" http://mysite.com/upload

I get exception thrown that my file type is not valid because original_filename has been set to the 'RackMultipart20130602-79blahblah', not myfile.jpg.

What Am I missing?

I added a demo to https://github.com/dblock/grape-on-rack/, https://github.com/dblock/grape-on-rack/blob/master/api/upload_file.rb. It worked with curl as well, without any changes.

Post the entire exception, please.
