Why doesn't rails_admin want to upload an image?

Question

Ruby on Rails

In general, I made a download from paperclip. Everything loads fine locally. When uploaded to the server and launched in production, when loading the image, the following error appears:
Image failed to be created
- Image has contents that are not what they are reported to be
after a long googling, it became known that it was swearing at the validator.
I have this:
validates_attachment_content_type :image, :content_type => ['image/jpeg', 'image/png']
tried to disable validation, but it didn't work(((

Answer 1

In general, I dug up such a solution at some American forum.
Make file: /config/initializes/paperclip.rb
require 'paperclip/media_type_spoof_detector'
module Paperclip
class MediaTypeSpoofDetector
def spoofed?
false
end
end
end
Who understands what this is and can explain why this solves the problem?
