Module: Tap::Controller::RestRoutes

Defined in:
lib/tap/controller/rest_routes.rb

Overview

Adds REST routing to a Tap::Controller.

class Projects < Tap::Controller
  include RestRoutes

  # GET /projects
  def index...

  # GET /projects/*args
  def show(*args)...

  # POST /projects/*args
  def create(*args)...

  # PUT /projects/*args
  # POST /projects/*args?_method=put
  def update(*args)...

  # DELETE /projects/*args
  # POST /projects/*args?_method=delete
  def destroy(*args)...

  # extension...

  # POST /projects/*args?_method=another
  def another(*args)...
end

Relation to RESTful Rails

Unlike the REST syntax in Rails, ‘/projects/new’ is treated like a show where the id is ‘new’. Also missing is the routing for urls like ‘/projects/arg;edit/’. See these resources:
