add simple_format to an Active Model Serializer attribute

Question

I'd like to simple_format the body of my CommentSerializer. I have:

class CommentSerializer < ActiveModel::Serializer
  attributes :id, :body 

  def body
    simple_format(body)
  end

but this goes into a recursive call. Ideally, I'd like to keep the body attribute as there is already front-end code using it. What would be an easy way to add this?

It goes in a loop because you call body from body. If you want to format the original model body, you need to use object.body.

def body
  simple_format(object.body)
end

Note that object is the reference to the object you pass when you initialize the serializer instance.

@StarWars `simple_format` is not available by default in a serializer, it's a helper. You need to include or redefine it. – Simone Carletti Dec 28 '15 at 10:17
@SimoneCarletti I included TextHelper in my serializer `class MySerializer < ActiveModel::Serializer include ActionView::Helpers::TextHelper` is this the correct way to do it. – lightsaber Dec 28 '15 at 10:37
