Module: Roda::RodaPlugins::Delegate

Defined in:

lib/roda/plugins/delegate.rb

Overview

The delegate plugin allows you to easily setup instance methods in the scope of the route block that call methods on the related request, response, or class which may offer a simpler API in some cases. Roda doesn't automatically setup such delegate methods because it pollutes the application's method namespace, but this plugin allows the user to do so.

Here's an example based on the README's initial example, using the request_delegate method to simplify the DSL:

plugin :delegate
request_delegate :root, :on, :is, :get, :post, :redirect

route do |r|
# GET / request
root do
  redirect "/hello"
end

# /hello branch
on "hello" do
  # Set variable for all routes in /hello branch
  @greeting = 'Hello'

  # GET /hello/world request
  get "world" do
    "#{@greeting} world!"
  end

  # /hello request
  is do
    # GET /hello request
    get do
      "#{@greeting}!"
    end

    # POST /hello request
    post do
      puts "Someone said #{@greeting}!"
      redirect
    end
  end
end
end
