Rendering a partial from Draper Decorator

I have a decorator that returns either a string, or a collection.

In my view, I want to display the return of this decorator method.

class MyDecorator < Draper::Decorator
  def stuff
    if condition
      'some string'
    else
      render model.some_collection
    end
  end
end

Now in my view I want to render the string if it's a string, or render the collection.

= my_object.stuff

Unfortunately I cannot access the render method inside Draper::Decorator. Thoughts?

Solution

  • From https://github.com/drapergem/draper#accessing-helpers:

    Normal Rails helpers are still useful for lots of tasks. Both Rails' provided helper and those defined in your app can be accessed via the h method

    So, replace render with h.render and it should work fine.
