I don't think so. Presenters and Presentation Models correspond to a single view from which they extract as much "intelligence" as possible. Whereas your plugin adds very generic presentation functionality to model objects/classes. (Yes, I know that the methods are not technically added to the model, but forwarding amounts to the same.) > I see that people are going to be hung up on the fact that the > forwarding code is on the model instead of on the presenter. Not me. I think it is worthwhile to explore extending model objects with view-specific code, *if* at the same time the different concerns of presentation and business logic can be kept separate. In the meantime I had a closer look at the code included with your original message. There are two layers: A lower layer consisting of Helpable, Helper, and supporting extensions to the functionality of ActionView and ActionController. Basically, this layer allows to add methods to each individual(!) model object assigned in a template. Above that, there is another layer that adds the same set of helper methods to all AR instances indiscriminately and another set of methods to arrays. What sticks out is an imbalance between the flexibility provided by the lower layer and what little of it the higher layer uses. If indeed no more flexibility is needed, then it would be a lot simpler to mix-in the helper methods into ActiveRecord::Base and Array and be done with it. OTOH, if there is a need to potentially have different implementations of helper methods, then the existing flexibility could be put to use.
