处理来自的文件 <select> Activeadmin表单中的字段

Question

I have a select that goes like this on one of my activeadmin forms:

f.input :sdfile, :as => :select, :collection => Dir.glob("incoming/*")

The user is supposed to upload the file to a "incoming" dir beforehand.

I now want to process this file, moving it to the proper folder, but CarrierWave refuses to "upload" from a pathname.

Any easy way to process the file, moving it to the respective folder?

Thanks.

Try it like this:

Image.new :data=>File.new("/path/to/image.jpg","r")

or

Image.new :data=>File.open('/path/to/image.jpg', 'rb')
