Relationship attribute unexpectedly creating document

Hello there,

I have a Relationship attribute as shown in the picture. I use pre-existing doctor documents to create a relationship and I noticed that every time I create a document with that relationship set with an existing document, the existing document gets created with a unique id. Is that unusual or is the intended behavior? Thanks

Existing document gets created with a unique id? What do you mean?

I might have misunderstood on how Relationships exactly work. So let me get it straight: Relationship attributes creates a link between documents right?

So for example if collection A has relationship with documents in collection B, and if we want to create a document in collection A with a relationship from a document of collection B that already exists, should the first document from collection A (the one we create) cause the creation of a new document (the one we want to build a relationship with) in collection B?

That seems a little confusing

You can create a document in the related collection or link an existing.

Maybe you can share your code

I implemented that in a production project and I had to quickly find another alternative. I will try to replicate that and share the code
