Creating 1:1 relationships in Graphback

[craicoverflow]

The only way to make a @oneToOne field truly 1:1 is by also adding @unique.

"""@model"""
type User {
  id: ID
  name: String
  """
  @oneToOne
  @unique
  """
  note: Note
}

Otherwise it is identical to a 1:M/M:1 relationship and is not restricted.

I see this as a bug. It would seem strange to have to add @unique aswell, as you would expect the @oneToOne annotation to handle this.

If it is a docs issue, cc @machi1990 as you are working on migrations docs right now.

No strong opinion but seems like code issue. Let's triage this

With Relational databases, GraphQL Migrations can take care of this.

I wonder how can have something similar for MongoDB without having to track relationships on code.
