AshJsonApi: Create relationship when creating resource

Questions & Help Questions
3

I did try that with #1.

{
  data: {
   attributes: {...attributes},
   relationships: {
     authors: [{type: "author", name: "Eliel", email: "q232"}]
   }
  }
}

This got somewhere but seems to need an id attribute in the relationship. When I add that none of the other attributes in the relationship make it to the changeset attributes under authors.

The other way was to put the relationship in the attributes

{
  data: {
   attributes: {
    ...attributes,
    authors: [{name: "Eliel", email: "q232"}]
   },
  }
}

This did not work either, gave a invalid attribute error
