How to observe relation in combination with findAndObserve

[saaymeen]

I have a screen that receives the post ID as a route parameter and would like to subscribe to all post and comment updates, how can I implement this with findAndObserve?

const enhance = compose(
	withDatabase,
	withObservables(['id'], ({ database, id }) => ({
		post: database.get('posts').findAndObserve(id),
		comments: // how to proceed here?
	})),
);

Following their documentation, you will arrive in something like this

import { of as of$ } from 'rxjs'

const enhance = compose(
  withDatabase,
  withObservables(['id'], ({ database, id }) => ({
    post: database.get('posts').findAndObserve(id),
  })),
  withObservables(['post'], ({ post }) => ({
    comments: post ? post.comments.observe() : of$(null),
  })),
);
