Custom serialization of scalar values

[sandstrom]

It would be nice if we could wire up the serializer to always transform certain scalar values a certain way. For example, all instances of Time may be transformed/serialized in a special way. Same with instances of Money or Duration.

For example, something like this:

# application_serializer.rb
class ApplicationSerializer
  include FastJsonapi::ObjectSerializer

  value_transformer Time do |value|
    value.utc.strftime('%Y-%m-%dT%H:%M:%SZ')
  end

  value_transformer Money do |value|
    "#{value.currency}-#{value.amount}"
  end

end

(obviously this can also be solved by repeating attribute blocks over and over again in every serializer where the value object occur, but the whole idea with serializers is to standardise behaviour, also when it comes to scalar serialization)

Let me know what you think! 😄

This would be really useful!

Similarly I need all datetime fields to be formated in Timestamp. Any suggestion?

It seems Netflix has abandoned this project. The community created a new fork to continue supporting this project. Please refer
