Büroklammer NoHandlerError für benutzerdefinierten Prozessor

Question

Ich versuche, ein hochgeladenes Video in verschiedene Formate zu konvertieren, aber ich erhalte eine Fehlermeldung

Video Modell:

class Video < ActiveRecord::Base 
    has_attached_file :video, { 
           preserve_files: true, 
           styles: { 
            ogg: { :processors => [:ogg_processor] }, 
           }, 
           url: '/tmp/paperclip/:rails_env/video/:style/:filename', 
           path: ':rails_root/public:url', 
          } 

    # paperclip: 
    validates :video, attachment_presence: true 
    validates_with AttachmentContentTypeValidator, attributes: :video, content_type: /\Avideo\/.*\Z/ 
    validates_with AttachmentSizeValidator, attributes: :video, less_than: 150.megabytes 
end 

Diese Variation von Optionen nicht funktionierte entweder:

has_attached_file :video, { 
           preserve_files: true, 
           processors: [:ogg_processor], 
           styles: { 
            original: {}, 
           }, 
           url: '/tmp/paperclip/:rails_env/video/:style/:filename', 
           path: ':rails_root/public:url', 
          } 

Prozessor:

# lib/paperclip_processors/ogg_processor.rb 
module Paperclip 
    class OggProcessor < Processor 
    def make 
     output = Tempfile.new([File.basename(@file.path), '.ogv']) 
     parameters = '--max_size 1280x1280 --output :output :input' 
     Paperclip.run('ffmpeg2theora', parameters, output: File.expand_path(file.path), input: File.expand_path(output.path)) 
     output 
    end 
    end 
end 

Fehler:

Answer 1

Okay, es war ein sehr dummer Fehler.

Ich schickte eine String anstelle einer File Objekt. Ich habe gerade File.new(video_file) getan und es hat funktioniert.
