require 'mime/types' module CarrierWave ## # This module simplifies the use of the mime-types gem to intelligently # guess and set the content-type of a file. If you want to use this, you'll # need to require this file: # # require 'carrierwave/processing/mime_types' # # And then include it in your uploader: # # class MyUploader < CarrierWave::Uploader::Base # include CarrierWave::MimeTypes # end # # You can now use the provided helper: # # class MyUploader < CarrierWave::Uploader::Base # include CarrierWave::MimeTypes # # process :set_content_type # end # module MimeTypes extend ActiveSupport::Concern module ClassMethods def set_content_type(override=false) process :set_content_type => override end end ## # Changes the file content_type using the mime-types gem # # === Parameters # # [override (Boolean)] whether or not to override the file's content_type # if it is already set and not a generic content-type, # false by default # def set_content_type(override=false) if override || file.content_type.blank? || file.content_type == 'application/octet-stream' new_content_type = ::MIME::Types.type_for(file.original_filename).first.to_s if file.respond_to?(:content_type=) file.content_type = new_content_type else file.set_instance_variable(:@content_type, new_content_type) end end rescue ::MIME::InvalidContentType => e raise CarrierWave::ProcessingError.new("Failed to process file with MIME::Types, maybe not valid content-type?
