Decorator Generator

Padrino provides generator support for quickly creating new decorators within your Padrino application. Note that the decorator tests are generated specifically tailored towards the testing framework chosen during application generation.

Very important to note that decorator generators are intended primarily to work within applications created through the Padrino application generator and that follow Padrino conventions.

Using the decorator generator is as simple as:

$ padrino-gen decorator User

Options	Default	Aliases	Description
root	.	-r	specify the root destination path
app	/app	-a	specify the application
destroy	false	-d	removes all generated files
namespace		-n	specify the name space of your padrino project

Examples

# app/controllers/posts.rb
SampleProject::App.controllers :posts do

  get :index do
    source = Post.all
    @posts = decorate(source)
    render 'posts/index'
  end

  get :show, with: :id do
    source = Post.find(params[:id])
    @post = decorate(source)
    # or
    @post = PostDecorator.new(source, context: self)
    render 'posts/show'
