Dispatches a PartController. Use like:

<%= part TodoPart => :list %>

will instantiate a new TodoPart controller and call the :list action invoking the Part’s before and after filters as part of the call.

returns a string containing the results of the Part controllers dispatch

You can compose parts easily as well, these two parts will stil be wrapped in the layout of the Foo controller:

class Foo < Application

def some_action
  wrap_layout(part(TodoPart => :new) + part(TodoPart => :list))
end

end

def part(opts={})
  res = opts.inject([]) do |memo,(klass,action)|
    memo << klass.new(self).dispatch(action)
  end
  res.size == 1 ? res[0] : res
end
