How to implement nested resources using jsonapi-resorces gem in rails?

Question

I have a Posts resource and a User Rating resource.

In mine, routes.rbI put a user rating in posts:

jsonapi_resources :posts do
  jsonapi_resources :user_ratings
end

This correctly showed the end point /posts/{id}/user-ratings.

However, when testing this endpoint with, {id}it returns everything user-ratings, not just those user-ratingsassociated with this message.

In my resource I have tried to add a message: has_many :user_ratingsI tried to add to user ratings has_one :post.

In my models, I added has_manyand belongs_to.

However, I am not trying to do anything to make the api return only user ratings associated with a specific post id.

Any insight would be appreciated, thanks.
