Some thoughts on real ViewModels for Draper 2.0

some_controller.rb

class SomeController < AC::Base
  def show
    foo = Foo.first
    bar = Bar.first
    
    show_model = ShowViewModel.new(foo, bar)

    render show_model
  end
end

# the view would have exactly one ivar defined, @model. it'd contain the same thing as show_model. No other ivars would be exported.
# by defualt, this would still render app/views/somes/show.html.erb, but you could override it:

class ShowViewModel < Draper::ViewModel
  def template_location
    "foo/bar"
  end
end

# this would then render app/views/foo/bar.html.erb

On a related, but exactly the same, note, I've been "presenter-izing" Draper models lately. Seems to work okay, but I'd image we could come up with a clean API to make it more simple. https://gist.github.com/3887381

Why not just use Cells or Apotomo widgets for this!? I plan to use Focused Controller, Draper and Cells/Apotomo in combintion myself. Perhaps even with decent exposure. A beautiful, encapsulated fully OO approach as I see it. We just need a few full examples of this stack in action... no need to reinvent the whole thing again and again IMO.

Cells is about multiple controllers and views per page. This is just one.
