Custom methods and separate model 2

[andrew2net]

Custom methods for map_content are called on a separate model

class TestModel
  attr_accessor :value
end

class Test < Lutaml::Model::Serializable
  model TestModel
  attribute :value, :string
  xml do
    root 'test'
    map_content to: :value, with: { to: :value_to_xml, from: :value_from_xml }
  end

  def value_to_xml(model, parent, doc)
    el = doc.create_element('cont')
    doc.add_text(el, model.value)
    doc.add_element(parent, el)
  end

  def value_from_xml(model, value)
    model.value = value
  end
end

> test = TestModel.new
> test.value='Val'
> Test.to_xml(test)
.../gems/ruby-3.3.3/gems/lutaml-model-0.3.30/lib/lutaml/model/xml_adapter/xml_document.rb:244:in `process_content_mapping': undefined method `value_to_xml' for an instance of TestModel (NoMethodError)

We had a similar problem with the map_element method #83
