You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: decimal_range_field.rb
    path of file: ./repos/form_core/test/dummy/app/models/fields/options
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module Fields::Options
  class DecimalRangeField < FieldOptions
    attribute :begin_from, :string, default: "unrestricted"
    enum begin_from: {
      unrestricted: "unrestricted",
      value: "value",
      offsets_before_end: "offsets_before_end"
    }, _prefix: :begin_from

    attribute :begin_value, :decimal
    attribute :fixed_begin, :boolean, default: false
    attribute :offsets_b
    
    def interpret_to(model, field_name, accessibility, _options = {})
      return unless accessibility == :read_and_write

      klass = model.nested_models[field_name]

      if begin_from_value?
        klass.validates :begin,
                        numericality: {
                          greater_than_or_equal_to: begin_value
                        },
                        allow_blank: true
        if fixed_begin
          klass.default_value_for :begin,
                                  begin_value,
                                  allow_nil: false
          klass.attr_readonly :begin
        end
