+= Action Presenter
0
+
0
+Inspired by : http://www.caboo.se/articles/2007/8/23/simple-presenters
0
+
0
+== Warning
0
+
0
+Works only with Edge Rails.
0
+
0
+== Install
0
+
0
+	ruby script/plugin install git://github.com/nmerouze/action_presenter.git
0
+
0
+== Usage
0
+
0
+Here's a presenter :
0
+
0
+	class ArticlePresenter < ActionPresenter::Base
0
+		def title
0
+			h @source.title
0
+		end
0
+	end
0
+
0
+And to call it in the views, there are 2 helpers :
0
+
0
+	<%= present(@article).title %> or <%= p(@article).title %>
0
+
0
+== Render files
0
+
0
+You can also render files for a presenter method :
0
+	
0
+	class ArticlePresenter < ActionPresenter::Base
0
+		def title
0
+			render :title
0
+		end
0
+		
0
+		def body
0
+			render :body, :msg => 'Hello World!'
0
+		end
0
+	end
0
+
0
+The partial for title will be located in app/presenters/article/_title.html.erb :
0
+
0
+	<%=h article.title %>
0
+
0
+The partial for body will be located in app/presenters/article/_body.html.erb :
0
+
0
+	<%= article.body + msg %>
0
+
0
+== Presenters in your plugins
0
+
0
+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.
