Retries an operation on an ActiveRecord until no StaleObjectError is being raised.
You can use retryable_record in 3 different ways:
require 'retryable_record' RetryableRecord.retry(user) do user.username = "foo" user.save! end
require 'retryable_record/import' RetryableRecord(user) do user.username = "foo" user.save! end
require 'retryable_record' class User < ActiveRecord::Base include RetryableRecord end user = User.first user.retryable do user.username = "foo" user.save! end
Optimistic locking (lock_version column)
ActiveRecord migration needs to support optimistic locking. See api.rubyonrails.org/classes/ActiveRecord/Locking/Optimistic.html
class CreateUsers < ActiveRecord::Migration def change create_table :users do |t| t.string :name t.integer :lock_version t. end end end

Note on Patches/Pull Requests
Fork the project.
Make your feature addition or bug fix.
Add tests for it. This is important so I don't break it in a future version unintentionally.
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
Send me a pull request. Bonus points for topic branches.
