attribute_query_methods

🏗️ Dynamic attribute query generators​

Metaprogram dynamic predicate methods (dirty?, present?, etc.) for model attributes, reducing boilerplate. Use define_method in a loop and handle boolean suffixes automatically.

class Resource
  ATTRS = %i[active archived]

  ATTRS.each do |attr|
    define_method("#{attr}?") { get_attribute(attr) }
    define_method("#{attr}!") { update_attribute(attr, true) }
  end
end
