imagemagick - How to resize already uploaded Paperclip images to s3 using reprocess? (Rails) -

i have model:

class propertyimage < activerecord::base has_attached_file :picture, storage: :s3, s3_credentials: config['s3'], s3_protocol: (rails.env.development? ? "http": "https"), styles: { thumb: '100x100>', large: '633x460>', medium: '301x240>' } end

i'm using rails (4.0.1), cocaine (0.5.4) , paperclip (3.5.4).

i want migrate old images (with no thumb, big , medium) , resize each, created rake script:

namespace :migrate_images desc "resize images in propertyimage" task start_migration: :environment propertyimage.not_migrated.find_each |pi| imageconverter.perform(pi) end end end

and imageconverter class:

class imageconverter def self.perform(pi) begin pi.picture.reprocess! pi.update_attributes!({migrated: true}) puts "propertyimage [#{pi.id}] has been migrated." rescue exception => e puts "propertyimage [#{pi.id}] has error. #{e}" end end end

now when run script maintain getting next error:

⇒ bundle exec rake migrate_images:start_migration [deprecated] i18n.enforce_available_locales default true in future. if want skip validation of locale can set i18n.enforce_available_locales = false avoid message. propertyimage [11] has error. validation failed: image paperclip::errors::notidentifiedbyimagemagickerror, image paperclip::errors::notidentifiedbyimagemagickerror, image paperclip::errors::notidentifiedbyimagemagickerror propertyimage [12] has error. validation failed: image paperclip::errors::notidentifiedbyimagemagickerror, image paperclip::errors::notidentifiedbyimagemagickerror, image paperclip::errors::notidentifiedbyimagemagickerror

please note read similar articles , added next end of application.rb:

paperclip.options[:command_path] = "/usr/local/bin/identify"

and made sure have imagemagick installed:

⇒ brew install imagemagick warning: have outdated version of /usr/bin/install_name_tool installed. cause binary bundle installations fail. can happen if install osx-gcc-installer or railsinstaller. restore it, must reinstall os x or restore binary os packages. warning: imagemagick-6.8.9-7 installed

any help highly appreciated.

please note if seek reproduce problem using rails console:
