Schienen 4.2, Büroklammer gem. Fehler beim Anhängen des DOCX-Typs, liest content_type als 'application/zip', obwohl der MIME-Typ registriert ist

Question

Ich habe einen MIME-Typ registriert, damit Paperclip den Inhaltstyp .docx der Datei application/vnd.openxmlformats-officedocument.wordprocessingml.document lesen kann.

In Tests wird der content_type jedoch immer noch als application/zip gelesen.

Irgendeine Idee warum? Um die Dinge frustrierender zu machen, wurden die .pptx und .xlsx MIME-Typen registriert, diese Tests bestanden (urgh).

config/initializers/mime_types.rb

Mime::Type.register 'application/vnd.openxmlformats-officedocument.wordprocessingml.document', :docx 
Mime::Type.register 'application/vnd.openxmlformats-officedocument.presentationml.presentation', :pptx 
Mime::Type.register 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet', :xlsx

    VALID_IMAGE_TYPES.include?(attachment_content_type) 
    end 
end 

Danke für die Hilfe.

Edit:

Gemäß dem von bkunzi01 angegebenen Link habe ich versucht, den folgenden Code ein. Es hat keine Wirkung, .docx Dateien noch Validierung fehlgeschlagen, während .pptx und .xlsx übergeben.

config/application.rb

Paperclip.options[:content_type_mappings] = { 
     docx: 'application/vnd.openxmlformats-officedocument.wordprocessingml.document', 
     pptx: 'application/vnd.openxmlformats-officedocument.presentationml.presentation', 
     xlsx: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet' 
    }

Es scheint, dass die neue Version von Büroklammer dieses Problem verursacht wurde. Downgrade auf Version 4.3.1 sollte Ihr Problem lösen
