Loading dynamic field names during serialization

[rishijain]

Assume I have a model User, and it has a field custom1 and has other fields like id, name. Now I have something like this:

class UserSerializer < Panko::Serializer
  attributes [:id, :name, :custom1]

end

And after serialization, the response looks like this:

[
   {
       id: 1,
       name: 'rishi'
       custom1: 'c1'
  },

   {
       id: 2,
       name: 'jain'
       custom1: 'c2'
  }
]

Now ideally I want to change the field name custom1 to something based on some logic. So it for first object, it can be "lookup-v1" and for second object in that response, it could be "lookup-v2".

Is there a way I can achieve this?
