ReferencesMany relation type

[bajtos]

A ReferencesMany relation embeds an array of foreign keys to reference other objects.

An example model instance:

{
  id: 1,
  name: 'John Smith',
  accounts: [
    "saving-01", "checking-01",
  ]
}

@bajtos Please assign the task to me.

In most frameworks, hasMany do this behaviour by default (return only ids), but when you pass { include: 'entity' }, it behave like embedded. What you think about it?

Is this relation not implemented in LB 4 yet?

[njtnestor]

I need this relation, when will be implemented? It is highly necessary to work with mongo

[DavidKrpt]

We are also using mongodb, and we have to either use hasManyThrough in those cases where referencesMany would be the obvious best choice according to mongodb data modelling best practices, or imitate referencesMany with custom repository methods. Either way it is inconvenient and has overhead costs.

If there are any details about the implementation of this feature, can you please share them ?

Also, can you recommend other workarounds besides the two I mentioned above?
