Make non ActiveRecord classes renderable

In order to render a new partial without being a “Rails” object we can rewrite the method to_partial_path to do so:

class Timeline
  def to_partial_path
    "timeline/timeline"
  end
end

Now we just need to create the view in app/views/timeline/_timeline.htm.erb and it’s going to work like a charm!

or, we can extend the ActiveModel::Naming to make it works as well:

class Timeline
  extend ActiveModel::Naming
end

Happy coding!
