Observers in sequel

[mybooking-es]

We are planning to migrate our application from DataMapper to Sequel. I haven't found a way to implement observers. Is it possible in Sequel?

Thanks

What actions/behavior do you want to observe?

Thank you for your answer.

We need to observe after_update on a concrete model. We are actually doing it in a custom class including DataMapper::Observer and observe a registered Model. We have different observers on the same model depending on the relationships.

Seems like something like the following would work:

class ModelToObserve < Sequel::Model
  def after_update
    # your code
    super
  end
end

Thank you. Could even built on a separate Module and be included? Our models are a little big and we try to separate some logic this way.

Definitely:

module MyObserver
  def after_update
    # your code
    super
  end
end

ModelToObserve.include MyObserver
