AcriveRecord (2.2.0) after_update callback and database transaction

rubyonrails-talk

Hi,

Does anyone know how can I execute some bit of code after transaction wrapping up activerecord update/save methods completed?

after_update and after_save filters are both wrapped into the same transaction, and I need to make external service (druby) aware of changes immediately after changes were made. Now - I use separate thread and sleep(1) in druby service to make it see changes, but it's not good enough solution. Any ideas how can do it?

Thanks, Hubert

Like you, I've used the sleep hack, because ActiveRecord doesn't currently have after_commit callbacks.

The only other solution would be to move the remote call to your controller, after the transaction block or save call. You can still leave the details of the remote call in the model, but just call it from the controller.
