Render an array with JSONAPI and Rails

Question

I am using jsonapi to render an object:

product = Product.find(1)
render json: ProductSerializer.new(product)

My question is, how should I serialize a list of products?

If I do this:

products = Product.all
render json: ProductSerializer.new(products)

It doesn't work, I get this error (which makes sense because I am trying to serialize an array and it doesn't have an id):

id is a mandatory field in the jsonapi spec

And If I serialize each product and return it in an array, like this:

response = []
products = Product.all
products.each do |product| 
  response << ProductSerializer.new(product)
end

Each object will have an included object, instead of having just one included appended to the response with all relationships...

And this is the ProductSerializer:

class ProjectSerializer
  include JSONAPI::Serializer
  
  set_type :product
  
  attributes :name
end

Answer 1

render json: serialize(products)

def serialize(data, serializer = ProductSerializer) serializer.new(data).serializable_hash[:data].map { |hash| >hash[:attributes]} end
