Overview

Dynamic accessor object for app-defined custom fields stored in metadata. Backed by the config.custom_fields schema, provides both hash-style and method-style access to field values.

Includes ActiveModel::Validations for type checking, required field enforcement, and unknown field detection.

Constructor Details

#initialize(schema, data = {}) ⇒ CustomFields

    parsed field data from metadata JSON

  @schema = schema || {}
  @data = (data || {}).transform_keys(&:to_sym)
end

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method_name, *args) ⇒ Object

Dynamic reader/writer access to custom field values. Only resolves field names that appear in the schema or already have a value in @data; unknown names fall through to super (raising NoMethodError).

Parameters:

  • method_name (Symbol)
  • args (Array)

Returns:

  • (Object)
