Action Pack is a framework for handling and responding to web requests. It
|
|
provides mechanisms for routing (mapping request URLs to actions), defining
|
|
controllers that implement actions, and generating responses. In short, Action
|
|
Pack provides the controller layer in the MVC paradigm.
|
|
|
|
It consists of several modules:
|
|
- Action Dispatch, which parses information about the web request, handles
|
|
routing as defined by the user, and does advanced processing related to HTTP
|
|
such as MIME-type negotiation, decoding parameters in POST, PATCH, or PUT
|
|
bodies, handling HTTP caching logic, cookies and sessions.
|
|
- Action Controller, which provides a base controller class that can be
|
|
subclassed to implement filters and actions to handle requests. The result of
|
|
an action is typically content generated from views.
|
|
|
|
With the Ruby on Rails framework, users only directly interface with the Action
|
|
Controller module. Necessary Action Dispatch functionality is activated by
|
|
default and Action View rendering is implicitly triggered by Action Controller.
|
|
However, these modules are designed to function on their own and can be used
|
|
outside of Rails.
