CopyCarrierwaveFile

Simple gem for copying CarrierWave files between resources. It's solving issues with local and remote storage discussed here

Installation

Add this line to your application's Gemfile:

gem 'copy_carrierwave_file'

And then execute:

$ bundle

Usage

You can use service class directly:

original_resource = User.last
new_resource      = User.new

CopyCarrierwaveFile::CopyFileService.new(original_resource, new_resource, :avatar).set_file
  # :avatar represents mount point (field)

new_resource.save

or you can include CopyCarrierwaveFile module and call copy_carrierwave_file :

class Document
  include CopyCarrierwaveFile  
  mount_uplader :content_file, MyUploader

  def duplicate_file(original)
    copy_carrierwave_file(original, self, :content_file)
    self.save!
  end
end

document = Document.new
document.duplicate_file(Document.last) 

Functionality is the same
