How to use alias_input with nested attributes

[paulomcnally]

Hi.

I have this code

play ->(result) { result.client_id = result.campaign_booking.client_id },
        ...

How to use alias_input to solve this?

I try with:

alias_input(client_id: :campaign_booking[:client_id]),

alias_input(client_id: :campaign_booking['client_id']),

alias_input(client_id: :campaign_booking.client_id),

But don't work.

Any idea?

Thanks! Sorry for my english.

Hey @paulomcnally!

alias_input won’t help you there, so calling:

play ->(result) { result.client_id = result.campaign_booking.client_id },
        ...

Is the shortest syntax you can have here.

If you’re doing this same assignment over and over again, something you do very often you could always create a small actor that reassigns, e.g.:

play AssignClientIdFromCampaignBooking,
     ...

with:

class AssignClientIdFromCampaignBooking < Actor
  input :campaign_booking
  output :client_id

  def call
    self.client_id = campaign_booking.client_id
  end
end
