ActionControllerMetal
ActionControllerMetal is a foundational component within the Ruby on Rails web framework. It serves as the base class for all controllers in a Rails application. Its primary purpose is to provide the core functionality for handling HTTP requests and generating HTTP responses. ActionControllerMetal is a stripped-down version of ActionController, omitting features that are often considered "higher-level" or optional in a typical Rails application. This minimal design makes it lightweight and allows developers to build custom controllers with only the necessary features.
The class is responsible for routing incoming requests to the appropriate controller actions. It parses request
Understanding ActionControllerMetal is crucial for developers who wish to deeply customize their Rails application's request handling
