Resolving array of IDs into objects, based on indentifiers and references

[esbenvb]

I have a store where I load in a list of authors, which is the type EgInteressent

The BulletinBoard contains a list of authors which are of the type EgInteressent.

The BulletinBoardPost contains an author field with the ID of an author and successfully resolves that ID into an element from the authors list of the BulletinBoard.

Now I want to add another field, likedBy which contains an array of IDs that should all be resolved into EgInteressent objects.

But the code I've tried to implement, does not resolve the IDs of the likedBy, as you can see in the comments.

What am I doing wrong?

// Props that both `BulletinBoardPost` and `BulletinBoardPostComment` share
export const BulletinBoardPostSharedProps = {
  postId: types.identifier,
  author: types.safeReference(EgInteressent), // this resolves to {"egInteressentNummer": "434343", "name": "Bobby Olsen"}
  body: types.string,
  likedBy: types.array(types.safeReference(EgInteressent)), // This remains like  ["454545", "434343"]
  files: types.maybe(types.array(File)),
  createDate: types.string,
}

export const EgInteressent = types.model('EgInteressent').props({
  egInteressentNummer: types.identifier,
  name: types.string,
})

export const BulletinBoard = types.model('BulletinBoard').props({
  boardId: types.identifier,
  name: types.string,
  authors: types.optional(types.map(EgInteressent), {}),
  posts: types.optional(types.array(BulletinBoardPost), []),
  isExhausted: types.optional(types.boolean, false),
  isLoading: types.optional(types.boolean, false),
})

I made it work. So apparently, I cannot console.log the values of a property of the store, I have to iterate through the array before I get the resolved values.

You made an example with really old MobX/MST versions.
I made a fork with updated versions: https://codesandbox.io/s/mobx-state-tree-todolist-forked-5ge7i?file=/index.js

And everything looks fine, including console.log.
