Which version of Paperclip do you use? There was a security issue with file types hence they changed the behaviour in version 4.0 of paperclip, but of course there was an error in 4.0 concerning content type mapping. In 4.1 they introduced a possibility to add options like so:
Paperclip.options[:content_type_mappings] = { :pem => "text/plain" } or not writing it with the rocket hash notation but with symbols you want to write Paperclip.options[:content_type_mappings] = { php: 'text/x-php' } I found the quoted solution there => https://github.com/thoughtbot/paperclip/issues/1462 On Friday, August 22, 2014 5:18:44 PM UTC+2, Ruby-Forum.com User wrote: > > Hello, > > I am learning rails and trying to use ckeditor and paperclip. > When I try and upload an image file, I get: > > [paperclip] Content Type Spoof: Filename 1.jpg (["image/jpeg"]), content > type discovered from file command: .
