Delayed Paperclip does not generate all styles in latest version of Paperclip (v 3.0.4)

[timols]

Currently, due to API changes in Paperclip from v3.0 onwards, the reprocess! method that is called from process_delayed! does not reprocess all of the styles since the post_processing instance attribute on the attachment is set to false after being created. When reassigned/saved this is not updated to true again.

This is easily overcome by updating the relevant method as follows:

  def process_delayed!
    self.job_is_processing = true
    self.post_processing = true
    reprocess!
    self.job_is_processing = false
  end

Happy to provide a pull request if appropriate.

Thanks mate, wrapped it in my recent commits to get S3 working:

aguilarsoto#2

So that now works for 2.7 -> 3.1.2 of paperclip and S3 uploads.

Nice. Thanks for issuing the pull request.

I am experiencing this same issue even with the following gems:

From Gemfile:
gem 'delayed_paperclip', '2.4.5.2', :git => 'git://github.com/tommeier/delayed_paperclip', :branch => 'fix_312'
gem 'paperclip', '~> 2.7.0'

From bundle show:

• delayed_paperclip (2.4.5.2 c23a537)
• paperclip (2.7.0)

My environment is

Rails 3.1.6
Ruby version:
ruby 1.8.7 (2011-02-18 patchlevel 334) [i686-linux], MBARI 0x8770, Ruby Enterprise Edition 2011.03

Is it my Ruby verison? Too old perhaps?

My photo model contains:
has_attached_file :file,
:styles => STYLES,
:default_style => DEFAULT_STYLE,
:convert_options => {
:new_square => '-auto-orient -thumbnail "x80" -resize "80x<" -resize 50% -gravity north -crop 40x40+0+0 +repage',
:new_thumbnail => '-auto-orient -thumbnail "x120" -resize "120x<" -resize 50% -gravity north -crop 60x60+0+0 +repage',
:new_small => '-auto-orient -thumbnail "x320" -resize "320x<" -resize 50% -gravity north -crop 160x160+0+0 +repage'
},
:storage => USE_S3 ? :s3 : :filesystem,
:s3_credentials => "#{::Rails.root.to_s}/config/amazon_s3.yml",
:path => USE_S3 ? PATH_FORMAT : ":rails_root/public/paperclip/#{PATH_FORMAT}",
:url => USE_S3 ? ":s3_alias_url" : "/paperclip/#{PATH_FORMAT}",
:s3_host_alias => ::Rails.env =~ /^prod/ ? 'files.mobicious.com' : "files-#{::Rails.env}.mobicious.com",
:s3_headers => {'Cache-Control' => 'max-age=315576000', 'Expires' => 10.years.from_now.httpdate}

Paperclip.interpolates :updated_at_timestamp do |attachment, style|
Time.at(attachment.updated_at).strftime("%Y/%m/%d/%H%M%S")
end

#process_in_background :file

Note that process_in_background is commented out to disable delayed_paperclip. (It works without it but the delays are unacceptable now)

Please advise.

Thanks,
Dan
