Relationship routes are created without adding them in the routes.rb

I've defined the following Resource:

class CommentResource < BaseResource
      has_one :activity
      has_one :user
end

 class ActivityResource < BaseResource
      has_many :comments
end

jsonapi_resources :activities, only: %w(index show)
jsonapi_resources :comments, only: %w(create destroy index show)

And checking with rake routes I see that it also created all the relationship/related routes for both Activity and Comment even if I haven't added jsonapi_links / jsonapi_related_resources in the routes file

Inizia con le dichiarazioni delle risorse e la configurazione di routes.rb mostrate nell’issue, quindi riproduci l’output con rake routes. Traccia il modo in cui vengono generate le route delle relazioni e le route correlate per ActivityResource e CommentResource. Il lavoro è completato quando l’elenco delle route corrisponde alle dichiarazioni delle relazioni e alle opzioni delle route configurate esplicitamente.
