few drafts this whole section was about Presenters. Then I started researching the history of the Presenter concept in Ruby and Rails. And the more I read, the less certain I became about my terminology. The idea of a Presenter was first introduced to the Rails community by Jay Fields in a series of blog articles in 2006 and 2007. Fields summarizes the Presenter pattern as follows: The Presenter pattern addresses bloated controllers and views containing logic in concert by creating a class
and modules. # # - :except is a list of classes, modules, and method names which # will be excluded from treatment. def hide(*stuff) hide_methods(self, [Object], *stuff) end # Like #hide, only hides methods at the class/module level. def hide_singletons(*stuff) hide_methods(singleton_class, [Class], *stuff) end # The shared bits of #hide and #hide_singletons def hide_methods(mod, except_defaults, *stuff) options = stuff.last.is_a?(Hash) ? stuff.pop : {} include_ancestors =
the model may be presented. The first dispatch, the call to #render_body, enables the post body partial to be determined polymorphically. The second dispatch, the call to template.render, farms the specific details of finding and rendering the chosen partial back out to the template object. Exhibiting the blog object It was easy enough to exhibit a single Post object at the controller level. It gets more complicated when we look at rendering multiple blog posts in the context of the front page.
Fowler summarizes GUI patterns. Note: this article is more concerned with rich client-side GUI patterns than web GUIs. • Model View ViewModel. A pattern from the .NET/Silverlight world. Views • Effigy replaces your view templates with honest-to-goodness objects. Among other interesting implications, this means that instead of layouts you simply have a base class which defines boilerplate HTML, and then individual view subclasses override the parts of the base which they wish to customize. •
