Hi Joel. I'm not quite sure why you want to render partials or templates from within your model(s). I'm sure you have some good reasons, but sometimes there're ways of accomplishing what you want without violating the "rules" of the MVC design pattern. Would you mind explaining in more detail why your model(s) need to render partials and/or templates?
