UpYun Storage engine for paperclip
This gem allows you to use UpYun Storage as storage engine for paperclip
Installation
gem install upyun-paperclip
Rails 3
gem "paperclip"
gem "upyun-paperclip", :git => 'git://github.com/frankel/upyun-paperclip.git'
Usage
If you have a model named User, then you can set options like this.
One model
class User < ActiveRecord::Base  
  has_attached_file :avatar,
  { 
    :storage => :upyun, 
    # Please set these four options found in your upyun account.
    :upyun_bucketname => 'bucketname',
    :upyun_username => 'username',
    :upyun_password => 'password',
    :upyun_domain => 'domain',
    
    # Set any other options according to paperclip
    :styles => { :medium => "300x300>", :thumb => "100x100>" }
  }
endMultiple models
If you have more than one model to use paperclip, and feel bored to set the same options for each one, you can create a file named paperclip.rb under config\initializers folder, and write code like this:
Paperclip::Storage::Upyun::Config = { 
  :upyun_bucketname => 'bucketname',
  :upyun_username => 'username',
  :upyun_password => 'password',
  :upyun_domain => 'domain'
}and only set :storage => :upyun in each models.
