Action Presenter

Inspired by : http://www.caboo.se/articles/2007/8/23/simple-presenters

Warning

Works only with Edge Rails.

Install

        ruby script/plugin install git://github.com/nmerouze/action_presenter.git

Usage

Here’s a presenter :

        class ArticlePresenter < ActionPresenter::Base
                def title
                        h @source.title
                end
        end

And to call it in the views, there are 2 helpers :

        <%= present(@article).title %> or <%= p(@article).title %>

Render files

You can also render files for a presenter method :

        class ArticlePresenter < ActionPresenter::Base
                def title
                        render :title
                end

                def body
                        render :body, :msg => 'Hello World!'
                end
        end

The partial for title will be located in app/presenters/article/_title.html.erb :

        <%=h article.title %>

The partial for body will be located in app/presenters/article/_body.html.erb :

        <%= article.body + msg %>

Presenters in your plugins

You can have presenters in plugins. Just create a directory app/presenters and you’re ready to go. It’s great if you have Engines too.
