Serialize attributes which is used serialize in active model definition

[danielmalaton]

Context:
Suppose I have User model like this:

class Rot13JSON
  def self.rot13(string)
    string.tr("a-zA-Z", "n-za-mN-ZA-M")
  end

  # Serializes an attribute value to a string that will be stored in the database.
  def self.dump(value)
    rot13(ActiveSupport::JSON.dump(value))
  end

  # Deserializes a string from the database to an attribute value.
  def self.load(string)
    ActiveSupport::JSON.load(rot13(string))
  end
end

class User < ActiveRecord::Base
  serialize :preferences, Rot13JSON
end

and UserSerializer class definition:

class UserSerializer < Panko::Serializer
  attributes :preferences
end

When serializing user instances:

# create user with non-nil preferences
user = User.create!(preferences: {...})

# serialize
UserSerializer.new.serialize(user) # { preferences: nil }

Expected

{ "preferences": {...} }

Got

{ "preferences": null }

Question:
Will you have the plan to fix it soon? I'm migrating from AMS to Panko and getting in trouble with it
