Paperclip::Globalize3

Use locale-specific attachments in your Rails app with paperclip and globalize3.

You can transparently read and write your attachments in context of the current locale. E.g. my_model.my_attachment returns a different attachment when your current locale is 'en' compared to when your current locale is 'de'.

Note that this implementation patches some methods in the Paperclip::Attachment class, so make sure you are okay with that.

Compatibility

Currently, paperclip 3.x (>= 3.3) and globalize3 0.3 are supported.

For paperclip 2.x support please use the 0.x versions of this gem.

Installation

Add this line to your application's Gemfile:

gem 'paperclip-globalize3'

And then execute:

$ bundle

Or install it yourself as:

$ gem install paperclip-globalize3

Usage

For each of your attachments which should have support for different locales, set up the following:

1. Migrate the paperclip columns ('xxx_file_name' etc.) of the attachment to the translation table
2. Declare in the model that it 'translates' the paperclip fields ('xxx_file_name' etc.)
3. Use the :locale interpolation for the paperclip url

NOTE: Make sure your translates are always defined after the has_attached_file! (Otherwise the files will not be deleted from the filesystem when the model is destroyed.)

Example:

class User < ActiveRecord::Base
  has_attached_file :avatar,
                    :url => "/system/:attachment/:id/:locale/:style-:fingerprint.:extension"
  translates :avatar_file_name, :avatar_file_size, :avatar_created_at, :avatar_updated_at, :avatar_fingerprint
end

Todo / Future Plans

• Make it easier to specify translated attachments, e.g. using one of these options:
  • support translates :attachment_name
  • support :translated option for has_attached_file
  • eliminate the need to specify; automatically set translates as soon as the :locale interpolation is used
• Don't depend on order of definition for it to work (translates after has_attached_file)
