Understanding after_update callback in Rails 4

Question

I have a Rails object with after_update callback that sends a record to a queue. And the problem is that I noticed sometimes the queue is being processed faster

Answer 1

If you consult the Rails documentation you will find a lot of callbacks you can use. The best for this job might be "after_commit":

This is straight from the Rails Docs (link at the bottom)

3.1 Creating an Object

before_validation
after_validation
before_save
around_save
before_create
around_create
after_create
after_save
after_commit/after_rollback

3.2 Updating an Object

before_validation
after_validation
before_save
around_save
before_update
around_update
after_update
after_save
after_commit/after_rollback

3.3 Destroying an Object

before_destroy
around_destroy
after_destroy
