Paperclip multiple spoof media type depending of 'file' version

Question

I have an application managing some files like .blend files.

.blend is not a standard mime type, so I add this options into config/environment.rb:

Paperclip.options[:content_type_mappings][:blend] = "application/octet-stream"

The value "application/octet-stream" is the value returned by the command

$ file -b --mime 'x.blend'
application/octet-stream; charset=binary
$ file -v
file-5.11

The issue I have is that the application is deployed on several servers, and they have not the same file version. For example, in an other server:

$ file -b --mime 'x.blend'
binary; charset=binary
$ file -v
file-5.17

So Paperclip detects a spoof

[paperclip] Content Type Spoof: Filename x.blend ([]), content type discovered from file command: binary. See documentation to allow this combination.

I tried to set content_type_mapping as an array (["application/octet-stream", "binary"]) but it doesn't work.

Have you any idea? Is it possible to disable this spoof check?

Answer 1

For thoses having same issue, my solution to allows multiple mappings was just accepted by Paperclip. You just have to get the last version of it.
