Some attributes mistakenly treated as unknown when working with lockbox and one_of

[dweinand]

Here's roughly the code I have:

class PlatformConfiguration < ActiveRecord::Base
  has_encrypted :properties, type: Properties.to_type
end

class PlatformConfiguration
  PROPERTIES_MODELS = {
    'platform' => 'PlatformProperties'
  }

  Properties = StoreModel.one_of do |json|
    const_get(PROPERTIES_MODELS.fetch(json[:platform_service], 'EmptyProperties'))
  end
end

class PlatformConfiguration
  class EmptyProperties
    include StoreModel::Model

    attribute :platform_service, :string
  end
end

class PlatformConfiguration
  class PlatformProperties
    include StoreModel::Model

    attribute :platform_service, :string
    attribute :api_key, :string
  end
end

I've verified that the types work correctly when manually casting values, however when I set values like platform_configuration.properties = {platform_service: 'platform', api_key: '12345'} && platform_configuration.save, properties.platform_service shows up correctly, but properties.api_key ends up showing up as an unknown attribute even though it's reporting the correct PlatformProperties type.

We're on:

• rails 8.1
• ruby 3.3.10
• store_model 4.3.0
• lockbox 1.4.1
