#initialize(path:, method: 'GET', action: nil, static: nil) ⇒ Route

A new instance of Route.

Parameters:

  • path (String, Regexp) —

    Path matcher, can be an String or Regexp with positional or named capture groups, @action will receive these as positional or named arguments. Always begins with /.

  • method (String, nil) (defaults to: 'GET') —

    Must be an HTTP verb such as GET or POST.

  • action (Proc, Hash, String, nil) (defaults to: nil) —

    References a Method/Proc to be triggered. It can be:

    • Nothing, defaults to :"#path_basename_#method" (such as :index_get) on :MainController.
    • A full hash { controller: 'val', action: 'val' }.
    • A hash with { Controller: :action } only.
    • A simple string for an action on :MainController.
    • It can also be a Proc. Will be executed in a :MainController instance context.
  • static (Boolean|Array) (defaults to: nil) —

    Defines a route as static. Defaults true for GET method, false otherwise. Set to false to say it can only work dynamically. You can also supply an array of arrays or hashes to generate static files based on that positional or keyword params.
