I think this is what you're looking for:

example copied from page

// Note: function passed to `database.write()` MUST be asynchronous
const newPost = await database.write(async => {
  const post = await database.get('posts').create(post => {
    post.title = 'New post'
    post.body = 'Lorem ipsum...'
  })
  const comment = await database.get('comments').create(comment => {
    comment.post.set(post)
    comment.author.id = someUserId
    comment.body = 'Great post!'
  })

  // Note: Value returned from the wrapped function will be returned to `database.write` caller
  return post
})
