How should I write multiple condition in after_create callbacks

Question

I have a method in model that calls after create

after_create :generate_insurer_recovery_invoice, if: :insurance_recovery_batch?

How should I write another condition within this callback?

Answer 1

You can also do this for a shorter readable version

after_save :update_offices_people_count, if: -> {office_id_changed? || trashed_changed?}

P.S: -> is a shorthand version of writing lambda.

not sure if this is a version issue, but i needed to put a comma before the "if" – Onestep

I do agree, right syntax is after_save :update_offices_people_count, if: -> {office_id_changed? || trashed_changed?} – Trail

Answer 2

I think this may be usefull to you

You can achive this something like this, from the following post

Multiple conditions on callbacks

after_save :update_offices_people_count

private

def update_offices_people_count
  if office_id_changed? || trashed_changed?  
    ...
  end
end

Have better solution with lambda after_save close_claim_for_unrecoverable, if: lambda {|di| di.unrecoverable? && di.unrecoverable_changed? } – Cheese

after_save close_claim_for_unrecoverable, if: lambda {|di| di.unrecoverable? && di.unrecoverable_changed? } – Cheese

Answer 3

Pass an Array of conditions.

The lambda or proc methods work well but you can also just pass in an Array to if, like so:

after_create :generate_insurer_recovery_invoice, if: [ :insurance_recovery_batch?, :active_insurer? ]

I'm not sure what version of Rails this was added but take a look at the Rails 7 docs here:
