Rails アプリを使用してビデオをアップロードしようとするたびに
次のエラーが表示されます。
ArgumentError (Missing host to link to! Please provide the :host parameter, set default_url_options[:host], or set :only_path to true):
app/uploaders/media_uploader.rb:64:in `zencode'
app/controllers/profile/videos_controller.rb:63:in `create'
ちなみにZencoderとCarrierwaveを使っています
これが私のmedia_uploader.rbです
# encoding: utf-8
class MediaUploader < CarrierWave::Uploader::Base
include Rails.application.routes.url_helpers
Rails.application.routes.default_url_options = ActionMailer::Base.default_url_options
# Include RMagick or MiniMagick support:
# include CarrierWave::RMagick
# include CarrierWave::MiniMagick
# Choose what kind of storage to use for this uploader:
#storage :file
after :store, :zencode
storage :fog
# Override the directory where uploaded files will be stored.
# This is a sensible default for uploaders that are meant to be mounted:
def store_dir
"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
def cache_dir
"#{Rails.root}/tmp/uploads"
end
# Provide a default URL as a default if there hasn't been a file uploaded:
# def default_url
# "/images/fallback/" + [version_name, "default.png"].compact.join('_')
# end
# Process files as they are uploaded:
# process :scale => [200, 300]
#
# def scale(width, height)
# # do something
# end
# Create different versions of your uploaded files:
# version :thumb do
# process :scale => [50, 50]
# end
# Add a white list of extensions which are allowed to be uploaded.
# For images you might use something like this:
def extension_white_list
%w(mp4 flv ogv avi)
end
# Override the filename of the uploaded files:
# Avoid using model.id or version_name here, see uploader/store.rb for details.
def filename
#"video.mp4" if original_filename
"video.mp4"
end

end

ところで、Heroku から AWS Ec2 への移行に関するものかどうかはわかりません。助けてください。
編集:
この行を設定しようとするたびに
:notifications => [zencoder_callback_url(:protocol => "http", :host => ENV['URL'], :port => ENV['PORT'])],
の中へ
:notifications => [zencoder_callback_url(:protocol => "http", :host => 'peekbox.tv', :port => ENV['PORT'])],
それは別のエラーとなりますw / cは
