You have to pass a hash of attribute names to values to create - you
can't just pass a value.
Files are just like any other attribute - you can't for example do
Person.create(params[:name]), you have to do Person.create(:name =>
params[:name]). In the same way you would do foo.uploads.create :file
=> params[:file]
