Use ActiveModel::Serializers to include two parent json arrays

Question

I\'m trying to send my front-end application json that looks like this:

{
  facilities: [
     {id: 5, name: \'happy days ranch\', location: { address: \'1424 Pa         


        

Answer 1

This is my solution:

render json: {
  facilities: ActiveModel::ArraySerializer.new(@facilities, each_serializer: FacilitySerializer, root: false),
  instructors: ActiveModel::ArraySerializer.new(@instructors, each_serializer: InstructorSerializer, root: false)
}

It's a little bit dirty. It basically instantiates what would be instantiated except done manually and twice. Both result sets are rendered using ActiveModel::Serializers in the correct format.
