Just some experimental rake tasks. The goal here is to simplify the process of pushing or pulling assets stored in the public/system directory of a Rails project.

git_sync.rake

namespace :git_sync do

  namespace :push do
    desc 'Push public/system files to staging'
    task :staging => :environment do
      do_rsync_push('staging')
    end
    desc 'Push public/system files to production'
    task :production => :environment do
      do_rsync_push('production')
    end
  end

  namespace :pull do
    desc 'Pull public/system files from staging'
    task :staging => :environment do
      do_rsync_pull('staging')
    end
    desc 'Pull public/system files from production'
    task :production => :environment do
      do_rsync_pull('production')
    end
  end
