proxy_method_missing

🔮 Building Dynamic Proxies with method_missing and respond_to_missing?

Implement method_missing alongside respond_to_missing? to craft transparent proxies or delegators. This pattern underpins ORMs or RPC clients that map arbitrary method names to remote calls.

class RemoteProxy
  def initialize(client)
    @client = client
  end

  def method_missing(name, *args)
    if name.to_s.start_with?('get_')
      @client.call_api(name.to_s.sub('get_', ''), *args)
    else
      super
    end
  end

  def respond_to_missing?(name, _)
    name.to_s.start_with?('get_') || super
  end
end

Always implement respond_to_missing? to keep introspection libraries happy.
