Rake task for migrating to panda/s3

migrator.rake

namespace :panda do
  desc "Migrate to panda/s3"
  task :migrate do
    
    FileAttachment.all.select(&:video?).each{ |fa|
      VideoAttachmentWorker.perform_async({
        title: fa.title,
        description: fa.description,
        recordable_id: fa.attachable_id,
        recordable_type: fa.attachable_type,
        source_url: fa.data.url
      })
    }
    
  end
end

I usually prefer find_each to batch operations like this rather than all.
Looks fairly simple in the end:)

So I guess this is going to complete relatively quickly on our end, but create a LOT of work for panda, which is how we want it. The logic on the recordable model to determine whether we can serve the new video is going to be important.
